The detailed modeling and mathematical simulation on perovskite solar cells have been performed with three various perovskite materials, such as “methyl ammonium lead trial halide (MAPbX 3 , MA= CH 3 NH 3 , X: I, Br, Cl)” with aid of solar cell capacitance simulator software (SCAPS) tools. The electrical possessions of MAPbX 3 material performed as “active layer” and measured different parameters such as “open-circuit voltage (V oc ), fill factor (FF), power conversion efficiency (PCE), and short-circuit current density (J sc ) respectively”. In the construction of the perovskite solar cell, cuprous oxide (Cu 2 O) material serves as “hole transport layer (HTL)”. The simulated results show that MAPbI 3 has better determined structural parameters (FF= 85.45, PCE= 28.69%, V oc = 1.20V, J sc = 27.84 mAcm -2 ) compared with MAPbBr 3 and MAPbCl 3 . All of the above measured parameter’s have been compared with other workers with existing experimental and reported values and show strong covenant with recorded values.

Low-dimensional bismuth-based perovskite solar cells (PSCs) have demonstrated some benefits over lead-based PSCs for nontoxicity and remarkable stability. These two factors are now the primary concerns in the photovoltaic community. The power conversion efficiency (PCE) of PSCs using the lead Pb-free chemical methylammonium bismuth iodide (CH3NH3)3Bi2I9 is severely limited due to the poor quality of the photoactive material. The objective of this study was to investigate the intrinsic impacts of (CH3NH3)3Bi2I9 perovskite by using SCAPS-1D (Solar Cell Capacitance Simulator) to simulate the PSCs and the adjustment of relevant physical parameters to closely match experimental results. Moreover, the cells were optimized based on (CH3NH3)3Bi2I9 film thickness, total defect density of (CH3NH3)3Bi2I9, optical bandgap, and interfacial defects. By conducting a comprehensive analysis of the current–voltage (J-V) plots and quantum efficiency (QE) feature, the best values of perovskite thickness, bandgap, and defect density were determined to be 100 nm, 1.6 eV, and 1014 cm−3, respectively. Furthermore, defects in the interfaces between the electron transport layer (ETL)/(CH3NH3)3Bi2I9 and hole transport layer (HTL)/(CH3NH3)3Bi2I9 were added, and their influence on performance was also investigated. Accordingly, the optimum cell has realized a record PCE of 9.043% and a high quantum efficiency exceeding 60%, which is comparable to those of some Pb-free perovskite analogues. The operational temperature calculations showed that all parameters remain relatively constant with increasing temperature. Therefore, the results imply that the simulated Pb-free PSCs can be stable in a thermal environment. The proposed structural layout and optimization approach can encourage more study and actual applications for Pb-free organometallic perovskite solar cells.

Strontium phosphorus chloride (Sr3PCl3) presents a promising option for photovoltaic (PV) applications due to its distinctive optical, electrical, and structural characteristics. This research uses density functional theory (DFT) to examine its structural stability and optoelectronic properties. The PV performance of Sr3PCl3-based cell designs was examined, utilizing an electron transport layer (ETL) of ZnO and four different hole transport layers (HTLs): Cu2O, CBTS, MoO3, and CuI. Essential parameters, including band alignment, layer thickness, defect density, doping concentration, interface defect density, carrier concentration, and generation-recombination rates, were consistently assessed via numerical simulations utilizing SCAPS-1D software. The findings indicated that the Cu2O HTL structure attained the highest power conversion efficiency (PCE) of 26.67%, with an open-circuit voltage (V OC) of 1.3 V, a short-circuit current density (J SC) of 22.79 mA cm-2 and a fill factor (FF) of 89.9%. The CBTS, MoO3, and CuI HTL designs attained PCEs of 26.39%, 24.86%, and 21.78%, respectively. To enhance device performance, the bifacial mode was investigated, and the PV efficacy of the proposed PSC structure was examined. Among these, the Cu2O-based structure shows the highest performance, attaining a bifacial factor of 87.21%, a bifacial gain of 16.74% and bifacial efficiency of 31.07%. These findings provide significant insights and propose a viable approach for the advancement of economic and excellent performance Sr3PCl3-based perovskite solar cells.
