Design of ZnO/Si heterojunction solar cell using solar cell capacitance simulator

Abstract

This study explores the optimization of ZnO/Si heterojunction solar cells to enhance device performance using a Solar Cell Capacitance Simulator. Solar cells have a lot of potential for converting solar energy into electricity efficiently & affordably. With the help of computational modeling, we study zinc oxide (ZnO) and Si Heterojunction (HJ) in order to enhance the device performance. By employing numerical methods such as, including drift-diffusion modeling and optical simulations, the charge transport within the heterojunction solar cells have been investigated. The effects of parameter variations on the device efficiency have been systematically explored and design approaches are identified to enhance the power conversion efficiency. This study investigates the performance of a ZnO-based solar cell, focusing on its electrical characteristics. The results show a short circuit voltage of 0.52 V, a current density of 19.64 mA/cm², and a fill factor of 0.78%. The power conversion efficiency of the ZnO-based solar cell is found to be 7.83% indicating its promising potential for application in solar energy conversion.
