“…In recent years, the use of organo-mineral perovskite compounds as light absorbers in the production of solar cells has been dramatically increased. [4][5][6][7][8][9][10] The materials with a chemical structure of ABX 3 are called perovskite, in which A is an organic or inorganic cation [CH 3 NH 3þ , CH(NH 2 Þ 2þ , Cs þ ], B is an inorganic cation (Pb 2þ , Sn 2þ , Ge 2þ Þ and X is an inorganic anion or polyanion (halides Cl À , Br À , I À Þ (Fig. 1).…”

Perovskite solar cells have recently been considered to be an auspicious candidate for the advancement of future photovoltaic research. A power conversion efficiency (PCE) as high as 22% has been reported to be reached, which can be obtained through an inexpensive and high-throughput solution process. Modeling and simulation of these cells can provide deep insights into their fundamental mechanism of performance. In this paper, two different perovskite solar cells are designed by using COMSOL Multiphysics to optimize the thickness of each layer and the overall thickness of the cell. Electric potential, electron and hole concentrations, generation rate, open-circuit voltage, short-circuit current and the output power were calculated. Finally, PCEs of 20.7% and 26.1% were predicted. Afterwards, according to the simulation results, the role of the hole transport layer (HTL) was investigated and the optimum thickness of the perovskite was measured to be 200[Formula: see text]nm for both cells. Therefore, the spin coating settings are selected so that a coating with this thickness for cell 1 is deposited. In order to compare the performance of HTM layer, solar cells with a Spiro-OMeTAD HTM and without the HTM layer in their structure were fabricated. According to the obtained photovoltaic properties, the solar cell made with Spiro-OMeTAD has a more favorable open-circuit voltage ([Formula: see text]), short-circuit current density ([Formula: see text]), fill factor (FF) and PCE compared to the cell without the HTM layer. Also, hysteresis depends strongly on the perovskite grain size, because large average grain size will lead to an increase in the grain’s contact surface area and a decrease in the density of grain boundaries. Finally, according to the results, it was concluded that, in the presence of a hole transport layer, ion transfer was better and ion accumulation was less intense, and therefore, the hysteresis decreases.

Effective conversion of solar photons into electrical power through the development of smart and eco‐friendly materials is one of the most extensively researched methods for generating renewable energy. In this work, an inorganic lead‐free double perovskite Cs2SnI6 material is employed as an active layer for solar cell applications, together with GO (graphene oxide) as electron transport layer (ETL) and Cu2O as hole transport layer (HTL). In order to find the most efficient photovoltaic device, a detailed theoretical study using the SCAPS‐1D simulation program is conducted. The device performance is monitored and analyzed by considering various HTLs, doping density in active layer, light intensity, ETL thickness, operating temperature, parasitic resistances, and the role of defects on device performance. The optimized device displays a power conversion efficiency of 23.64% with excellent photovoltaic characteristics. This theoretical study reveals that Cs2SnI6 can be a promising choice for solar cell applications as a lead‐free double perovskite material.

“…As shown in Table 1, the thickness of FTO (500 nm), TiO 2 (120 nm), and CuO (100 nm variable) were initially tuned for high PCE.

The Scaps-1d simulator was used to simulate a lead-free perovskite CH 3 NH 3 SnI 3 based solar cell devices fabricated from different hole transport materials (HTM). This research looks at two organic and two inorganic HTM layers. The cell structure used in this study is FTO/TiO 2 / CH 3 NH 3 SnI 3 /HTM(variable)/Au(variable). Spiro-OMeTAD, PEDOT:PSS, CuO and Cu 2 O are the HTM materials used. The results show that utilizing CuO as an HTM produces better outcomes than other HTMs, with an e ciency of 28.45%. The thickness, acceptor concentration (N A ), and defect density (N t ) of the perovskite layer on optoelectronic properties of the solar cell are focus of simulation studies. According to this study, an perovskite layer thickness of 1000 nm is suitable for a decent photovoltaic cell. Furthermore, by adjusting the HTM thickness and the defect density of HTM and absorber layer, promising ndings of J sc of 34.38 mAcm − 2 , V oc of 1.011 V, FF of 80.85% and PCE of 28.10% were obtained for Spiro-OMeTAD based PSC. Finally, in order to improve the device's performance, an anode material with high work function is required. Our ndings reveal that using a thin absorber layer results in low photo generated charge carriers due to less absorption, but high carrier extraction. Although more carriers are created in the cell due to increased absorption, decreased collection e ciency is related to recombination, which decreases V oc for thick perovskite layers. Device e ciency is improved by increasing the doping density up to 10 18 cm − 3 in the perovskite layer due to built-in electric eld across the solar cell. Again a very thin or thick HTL is not ideal for high PCE. For low recombination and a high ll factor, an HTM (Spiro-OMeTAD) of 1-100 nm is necessary. The great power conversion e ciency of organic HTM based lead-free PSC brings up the new possibilities for obtaining renewable energy.
