Theoretical study of perovskite solar cell for enhancement of device performance using SCAPS-1D

Abstract

Perovskite solar cells are a pioneering photovoltaic technology that has signif-icantly improved performance in current years. The fundamental n-i-p planar het-erojunction structure of solar cells is structured and simulated in the present work. The device configuration Glass/ITO/WS2/CH3NH3PbI3/P3HT/Au was investigated using the Solar Cell Capacitance Simulator (SCAPS-1D) program. To increase the performance of the photovoltaic solar cell thickness, bandgap, doping concentration and temperature have been varied. Further, using the optimal value of the different parameters, the performance of the photo-voltaic device such as power conversion efficiency (PCE) and Fill Factor (FF) are obtained as 27.02%, and 85.44%, respectively. Also, Open-circuit Voltage (VOC) of 1.46 V and Short-circuit current density (JSC) of 21.56 mA/cm2 were achieved. The influence of donor concentrations has been studied by varying its value from 1x10-12 cm-3 to 1x10-20 cm-3 for the proposed device. Thus, using different charge transport materials, the power convergence efficiency of the perovskite solar cell has been enhanced. Our simulation study reveals that the proposed configuration could be used to fabricate a device for the improvement of the efficient perovskite solar cell.

Comparative Study of Distinct Halide Composites for Highly Efficient Cesium-Based Perovskite Solar Cells

“…In the past ten years, numerous investigators have conducted studies on perovskite solar cells (PSCs) and observed a substantial improvement in their PCE. − The exceptional characteristics of these materials, such as a significantly high absorption coefficient, an adjustable band gap, an extended carrier diffusion length, enhanced carrier mobility, a reduced trap state density, a lower excitons binding energy, and a cost-effective processing method, have facilitated their achievement of this remarkable accomplishment. − The typical perovskite composition is presented by the chemical formulation ABX 3 , wherein A represents an inorganic or organic cation (MA, FA/Cs) and B represents a heavy metal (Sn, Pb, Ge), followed by an X signifying a halide anion (Cl, Br, and I). − The hybrid organic–inorganic perovskites have blazed a trail toward a more efficient light-harvesting material. PSC efficiency has now increased from 3% to 25.6%. − The versatile frequency of the PSCs enables them to efficiently capture the light of varying frequencies in different layers, thereby enhancing PCE. − …”
