    = Minu Mohan, in Perovskite Photovoltaics, 2018. c Copyright © 2021 Elsevier B.V. or its licensors or contributors. The fabricated device structure was glass or PET/SWCNTs/PEDOT:PSS/CH3NH3PbI3/PC61BM/Al, in which SWCNT film acted as an electron blocking layer. PSC have emerged from solid state DSSCs. [6] Their high absorption coefficient enables ultrathin films of around 500 nm to absorb the complete visible solar spectrum. Improving stability is a major aspect for commercial application of perovskite solar cells (PSCs). These materials can generate occupational health hazards when handled. A cations with radii between 1.60 Å and 2.50 Å were found to form perovskite structures. In particular, Cation Exchange Resins (CERs) and P,P′-di(2-ethylhexyl)methanediphosphonic acid (DMDP) have been employed experimentally in this effort. The project has the objective to reach module cost below 0.40€/Wp (Watt peak). Perovskite solar cells function efficiently in a number of somewhat different architectures depending either on the role of the perovskite material in the device, or the nature of the top and bottom electrode. [179] improved upon this in 2011, using the same dye-sensitized concept, achieving 6.5% PCE. A common concern is the inclusion of lead as a component of the perovskite materials; solar cells based on tin-based perovskite absorbers such as CH3NH3SnI3 have also been reported with lower power-conversion efficiencies.[13][14][15][16]. However, Sun et al. The electrical energy requirement for MA iodide is high. Interfacial energy alignment and charge-transfer (carrier-collection) processes 1.3. [176] This case is special to perovskite/silicon tandems since the temperature dependence of both the silicon and perovskite bandgaps—which follow opposing trends—shifts the devices away from current matching for two-terminal tandems that are optimized at standard test conditions. Perovskite solar cells (PSCs) are ideal candidates for TSCs due to their tunable band gaps, high PCE up to 25.2%, and easy fabrication. [4] 18.4), which have now reached 22.7% [2]. Protecting the perovskite layer from moisture is key to preventing excess water from forming on the layer itself, as it can damage the crystallinity of the cell structure, which affects overall performance. A perovskite solar cell (PSC[1]) is a type of solar cell which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. Experiments showed a substantial reduction in lead leakage from PSCs using these self-healing polymers under simulated sunny weather conditions and after simulated hail damage had cracked the outer glass encapsulation. demonstrated in June 2018 a fully textured monolithic tandem cell with 25.2% efficiency, independently certified by Fraunhofer ISE CalLab. While metal halide perovskite semiconductors represent a promising component for state-of-the-art solar cell technologies, they are plagued by nonradiative recombination, an undesirable electron-level process that reduces efficiency and exacerbates heat losses. Moreover, global PSC market value is estimated to be USD 214 million by 2025 (Suganthi and Samuel, 2012). [27][28][29][30], The solution-based processing method can be classified into one-step solution deposition and two-step solution deposition. c Heating,[44] gas flow,[45] vacuum,[46] and anti-solvent[34] can all assist solvent removal. In this test, the module was cracked by simulated hail damage, and placed in a solution of acidic water containing aqueous Ca2+ ions, meant to simulate acidic rain with low levels of aqueous Calcium present. Moreover, the perovskite solar cells can be deposited by low-temperature methods such as solution process viz. Then the mixture is spin coated on a substrate maintained at higher temperature. They also combined the bottom cell with a ~1.58 eV bandgap perovskite top cell to create an all-perovskite tandem solar cell with four terminals, obtaining a steady-state PCE of 21.0%, suggesting the possibility of fabricating high-efficiency all-perovskite tandem solar cells. The short-circuit current density of the device was observed to increase with the power density of the 980 nm excitation laser with >0.85 mA cm−2 obtained for 45 W cm−2 [94]. PVD refers to the evaporation of a perovskite or its precursor to form a thin perovskite film on the substrate, which is free of solvent. [182] A combined power conversion efficiency of 20.2% was claimed, with the potential to exceed 30%. [130] But a method to quantify the intrinsic chemical stability of hybrid halide perovskites has been recently proposed. Perovskite solar cells are thin films of synthetic crystalline made from cheap, abundant chemicals like iodine, carbon, and lead. A 13.4% efficient tandem cell with a highly efficient a-Si:H/c-Si heterojunction bottom cell using the same configuration was obtained. The maximum accepted levels of lead in drinking water and air were set to 15 and 0.15 μg/L, respectively, by the US EPA (Paulose, 2014; USA Environmental Protection Agency, n.d.). Inspection of the inorganic-organic perovskite via Circular Dichroism (CD) spectroscopy, reveals two regions. What's left is an ultra-smooth film of perovskite crystals. This led to the hypothesis that a scaffold is not needed for electron extraction, which was later proved correct. v The vapor phase deposition processes can be categorized into physical vapor deposition (PVD) and chemical vapor deposition (CVD). There are currently a variety of different technologies in use to convert solar energy into electricity. This can be easily dissociated in the presence of highly polar solvent such as water. u [109][110] The primary energy consumption by gold cathode is very high. The sparsity of the CNT network allows the device to be illuminated from both sides, which makes the application of solar cells as a window a possibility. But other factors contribute significantly to various environmental impacts. [174] Nowadays, the research teams show effort to utilize more solution-based scalable techniques on textured bottom cells. There is another different class of architectures, in which the transparent electrode at the bottom acts as cathode by collecting the photogenerated p-type charge carriers. In two-step deposition method, the volume expansion during the conversion of lead halide to perovskite can fill any pinholes to realize a better film quality. Critical issues are the stability of the organic spiro-OMeTAD layer and that of the perovskite with the Pb-free compounds. [26] Meanwhile, the hybrid organic-inorganic perovskite material can be manufactured with simpler wet chemistry techniques in a traditional lab environment. Further experiments in replacing the mesoporous TiO2 with Al2O3 resulted in increased open-circuit voltage and a relative improvement in efficiency of 3–5% more than those with TiO2 scaffolds. [180][181] Also, Aydin et al. Perovskite Solar Cells: Review of the Technology and Benefits Let’s review the progress made with perovskite solar cells since they were introduced in 2009. Therefore in this chapter PSC characteristic, application, and challenges have been briefly discussed. [169] Important parasitic absorption losses due to the use of Spiro-OMeTAD were still limiting the overall performance. Young children absorb 4–5 times as much lead as adults and are most susceptible to the adverse effects of lead. Currently, to make TiO2 layer deposition be compatiable with flexible polymer substrate, low-temperature techniques, such as atomic layer deposition,[51] molecular layer deposition,[52] hydrothermal reaction,[53] and electrodeposition,[54] are developed to deposit compact TiO2 layer in large area. Process cost and complexity is significantly less than that of silicon solar cells. T. Grace, ... J.G. [95][96][97][98] Also there have some efforts to cast light on the device mechanism based on simulations where Agrawal et al. Values of the detailed balance limit are available in tabulated form[93] and a MATLAB program for implementing the detailed balance model has been written. The ambiguity in determining the solar cell efficiency from current-voltage characteristics due to the observed hysteresis has also affected the certification process done by accredited laboratories such as NREL. Perovskite solar cell (PSC) includes the perovskite-structured material as an active layer based on the solution processed by tin or halide. In 2014, Olga Malinkiewicz presented her inkjet printing manufacturing process for perovskite sheets in Boston (US) during the MRS fall meeting – for which she received MIT Technology review's innovators under 35 award.

The PSC uses ABX3 crystal structure known as perovskite structure as an active light-harvesting layer. The incorporation of NaYF4:Yb3+, Er3+ nanoparticles as the mesoporous electrode led to a short-circuit current density of 0.74 mA cm−2 upon excitation with 980 nm laser with 28 W cm−2 [93]. An important change was demonstrated by Bush et al., who inverted the polarity of the top cell (n-i-p to p-i-n). There is an ongoing search for moisture stability in perovskite solar cells (PSCs), as protecting the perovskite layer from moisture is key to preventing excess water from forming on the layer itself and affecting overall performance. [176] In the case of TiO2-based devices, sintering consumes the major portion of energy. A diverse class of layered, crystalline minerals commonly found in nature, researchers are now able to fabricate perovskite solar cells just half a micrometer (0.5 x 10-6m) in length or width with a wide variety of chemical compositions, physical characteristics and performance attributes cheaply using common, inexpensive, “wet chemistry” i.e. When the CER was integrated into a carbon-based electrode paste applied to PSC and on the top of the encapsulating glass, the lead leakage decreased by 98%. [81], Chemically lead-binding coatings have also been employed experimentally to reduce lead leakage from PSCs. [173] In March 2020, KAUST-University of Toronto teams reported tandem devices with spin-casted perovskite films on fully textured textured bottom cells with 25.7% in Science Magazine. [144], Early in 2019, the longest stability test reported to date showed a steady power output during at least 4000 h of continuous operation at Maximum power point tracking (MPPT) under 1 sun illumination from a xenon lamp based solar simulator without UV light filtering. In one-step solution processing, a lead halide and a methylammonium halide can be dissolved in a solvent and spin coated onto a substrate. DSSC and organic solar cells are also classified as nanostructured solar cells which use lots of nanomaterials in manufacturing. In 2016, Chen et al. If there is large density of traps in the devices or photocurrent hysteresis for other reasons, the photocurrent would rise slowly upon turning on illumination[107] This suggests that the interfaces might play a crucial role with regards to the hysteretic IV behavior since the major difference of the inverted architecture to the regular architectures is that an organic n-type contact is used instead of a metal oxide. And u Is the ultimate efficiency factor, v is the ratio of open circuit voltage to band-gap voltage, and m is the impedance matching factor. {\displaystyle x_{g}=v_{g}/v_{s}\ ;\ x_{c}=v_{c}/v_{s}}. The improvement in device performances is attributed to the unique characteristics such as a broad spectral absorption range, very high absorption coefficient, high carrier mobility, longer diffusion length, and longer carrier lifetime. Furthermore, this is an inexpensive approach. Under these conditions, only thermal stress was found to be the major factor contributing to the loss of operational stability in encapsulated devices. v Unlike silicon solar cells, PSCs are less expensive and fabrication can be done by simple wet chemical process. By having multiple bandgaps in a single cell, it prevents the loss of photons above or below the band gap energy of a single junction solar cell. then improved this performance replacing the SnO2 layer with PCBM and introducing a sequential hybrid deposition method for the perovskite absorber, leading to a tandem cell with 21.2% efficiency. [5] To be able to compare results from different institution, it is necessary to agree on a reliable measurement protocol, as it has been proposed by [151] including the corresponding Matlab code which can be found at GitHub. v The efficiency improved from 5.14% to 6.87% after replacing the Au with CNT because CNT films can provide a stronger driving force for the hole injection according to the band alignment. The observation of hysteretic current-voltage characteristics has thus far been largely underreported. [168] Werner et al. n Vacuum-free deposition of back electrode is important to fully imploit the solution processibility of PSCs. [153] This type of cells have higher efficiency potential, and therefore attracted recently a large attention from academic researchers. g [70][71] Although the 50 % lethal dose of lead [LD50(Pb)] is less than 5 mg per kg of body weight, health issues arise at much lower exposure levels. v A partially functionalized SWNCT film has been used as a front transparent conducting electrode in place of the ITO electrode in perovskite solar cells. showed the highest certified short-circuit currents of 19.8 mA/cm2 on fully textured silicon bottom cells. P. Mathan Kumar, ... Ranjith G. Nair, in Perovskite Photovoltaics, 2018. [120] In November 2014, a device by researchers from KRICT achieved a record with the certification of a non-stabilized efficiency of 20.1%. In a short span of 5 years, efficiency has reached 22.1%, which could be an energy revolution in the future. ) This chapter discusses the various reported standard fabrication techniques for the deposition of photoanode, perovskite layer, electron/hole transport layers, counter electrode, and factors affecting the stability and life time of PSCs. [25] Traditional silicon cells require expensive, multi-step processes, conducted at high temperatures (>1000 °C) under high vacuum in special cleanroom facilities. have proposed 'stabilized power output' as a metric for the efficiency of a solar cell. This approach will be very helpful in developing low-cost, efficient, highly stable perovskite solar cells that can create a revolution in the solar cell market. [41] This could be applicable for the production of multi-junction cells. Generally, PSC have TCO/metal oxide/perovskite/HTM/metal architecture. Nevertheless, the system process is using acids and solvents in huge quantities to make third-generation solar cells as well. [74], Research done on Tin halide-based PSCs show that they have a lower power conversion efficiency (PCE), with those fabricated experimentally achieving a PCE of 9.6%. Here, we report the pretreatment of FASnI3 (formamidinium, FA This indicates that the origin of hysteresis in photocurrent is more likely due to the trap formation in some non optimized films and device fabrication processes. [141] The front coating can prevent the UV light of the whole incident solar spectrum from negatively interacting with the PSC stack by converting it into visible light, and the back layer can prevent water from permeation within the solar cell stack. [43], In order to scale up the perovskite layer while maintaining high efficiency, various techniques have been developed to coat the perovskite film more uniformly. The LCA studies show that the environmental impacts caused by lead are negligible when compared to MA iodide. Thin-film perovskite solar cells have emerged as an inexpensive and revolutionary type of photoactive semi-conductor in thin-film solar photovoltaics (PV), with a 22 per cent power conversion efficiency (PCE) rating. It has recently been reported that charges in the perovskite material are predominantly present as free electrons and holes, rather than as bound excitons, since the exciton binding energy is low enough to enable charge separation at room temperature.[89][90]. Third generation of photovoltaic (PV) cells has come up with the technologies like dye-sensitized solar cells, PSCs, organic PV, and quantum dot PVs. [147][148] However, initial studies have been published that show that surface passivation of the perovskite absorber is an avenue with which efficiency values can be stabilized very close to fast-scan efficiencies. The flexibility of making highly efficient solar cells with solid-state DSSCs will have less complication in the manufacturing process, easy possibility for producing monolithically interconnected modules, easier sealing and encapsulation of the modules which are similar to other TF solar cells. ) By adding spiro-OMeTAD (hole transporting substances), the performance of the devices was further improved to 9.9%. Australian scientists at the University of Queensland have designed a perovskite solar cell based on a mix of 2D and 3D salts. [24], Perovskite solar cells hold an advantage over traditional silicon solar cells in the simplicity of their processing and their tolerance to internal defects. The alternative to lead is being researched to be replaced in perovskite solar cells. [122] The instability of PSCs is mainly related to environmental influence (moisture and oxygen),[123][124] thermal stress and intrinsic stability of methylammonium-based perovskite,[125][126][127] and formamidinium-based perovskite,[128] heating under applied voltage,[129] photo influence (ultraviolet light)[130] (visible light)[126] and mechanical fragility. Perovskite solar cells – funny name, serious tech. June 2018 Oxford Photovoltaics 1 cm² perovskite-silicon tandem solar cell has achieved a 27.3% conversion efficiency, certified by the Fraunhofer Institute for Solar Energy Systems ISE. No obvious hysteresis of photocurrent was observed by changing the sweep rates or the direction in devices or the sweep rates. One such factor is the use of gold as a back electrode. Perovskite solar cells (PSCs) are the most emerging area of research among different new generation photovoltaic technologies due to its super power conversion efficiency (PCE). A perovskite solar cell (PSC ) is a type of solar cell which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. This exceeds the 26.7% efficiency world record for a single-junction silicon solar cell. Perovskite solar cells are a novel type of device that was first fabricated in 2009 (174) and several structures have been reported (175). in solution. Charge separation can then occur through two possible primary reactions: injection of photogenerated electrons into metal oxide nanoparticles, and/or injection of holes into a HTM, such as spiro-OMeTAD. [5], In 2018, a new record was set by researchers at the Chinese Academy of Sciences with a certified efficiency of 23.3%.[5]. [11] The first use of perovskite in a solid state solar cell was in a dye-sensitized cell using CsSnI3 as a p-type hole transport layer and absorber. [83] A similar test was also performed on a PSC module with DMDP coated on both the top and bottom of the module to study the efficacy of DMDP in reducing lead leakage. [138] The PbI2 residue in perovskite film has been experimentally demonstrated to have a negative effect on the long-term stability of devices. This was based on a dye-sensitized solar cell architecture, and generated only 3.8% power conversion efficiency (PCE) with a thin layer of perovskite on mesoporous TiO2 as electron-collector. [102] tries to come up with a compact model for perovskite different structures based on experimental transport data. Aruna Ivaturi, Hari Upadhyaya, in A Comprehensive Guide to Solar Energy Systems, 2018. [19], Utilizing organic chiral ligands shows promise for increasing the maximum power conversion efficiency for halide perovskite solar cells, when utilized correctly.
