Numerical simulation and performance optimization of perovskite solar cell

The organic-metal halide perovskite is emerging technology in photo voltaic solar cells. For any solar cell to get the significant efficiency depends on various design parameters such as material thickness, device architecture, doping concentration etc.. There are many solar cell simulation software which can be used to carry out simulation and thus optimization based on those parameters. Here for this research, we are using wxAMPS because it is freely available, simple, efficient and quite popular in solar cell research society. Keeping external parameters constant (one-sun, AM1.5G solar radiation, 1000 w/m ² irradiation), numerical simulation and analysis of a perovskite solar cell with configuration ETM/Perovskite/HTM was carried out. In the proposed configuration Zinc oxide (ZnO) was used as Electron Transport Material (ETM) as, mixed halide perovskite (CH ₃ NH ₃ PbI _3-x Cl _x ) was used as absorber material, and Copper thiocyanate (CuSCN) was used as Hole transport material (HTM). The performance of the solar cell was optimized using layer by layer optimization techniques. The results show a significant enhancement in conversion efficiency of 14.4% (Jsc = 15.44 mA/cm ² , Voc = 1.08 V, and FF = 0.85). The solar cell need further optimization which is under progress. However these simulation results can help researchers to reasonably choose materials and optimally design high-performance perovskite solar cells.
