Abstract

Perovskite solar cells (PSCs) have a high-power conversion efficiency that exceeds 20%, distinguishing them from other new photovoltaic technologies. The Solar Cell Capacitance Simulator (SCAPS-1D) was used in this study to investigate the effects of absorber layer properties on photovoltaic solar cell performance. SCAPS simulation software employs a numerical simulation technique to fully comprehend the principles of solar cell operation and predict the best power conversion efficiency. A three-layer solar cell model comprised of an Electron Transport Layer (ETL), a Hole Transport Layer (HTL), and a Perovskite Absorber Layer was used in this study. The variations in Voc, Jsc, FF, and PCE were investigated by varying the thickness of the absorber layer. The purpose of this research is to find the absorber layer thickness that produces the highest efficiency for two different ETM layer ZnO and SnO2. This simulation model can significantly aid in the fabrication of high-efficiency ZnO and SnO2 based PSCs.

Key findings

  • Varying absorber layer thickness affects Voc, Jsc, FF, and PCE in perovskite solar cells.
  • ZnO and SnO2 ETM layers have different optimal absorber layer thicknesses for maximum efficiency.
  • Simulation results show that absorber layer thickness significantly influences PSC performance.
