Abstract
This paper delves into the indoor performance analysis of Perovskite/Silicon Tandem Solar Cells (PSSTC) through a detailed exploration utilizing numerically modeled energy band diagrams. The primary objective is to uncover the potential of PSSTC for solar energy conversion in indoor settings. Various tandem cell configurations are scrutinized under diverse artificial lighting spectra, with an innovative Li4Ti5O12/ CsPbCl3/MAPbBr3/CH3NH3PbI3/ Si architecture achieving an exceptional maximum power conversion efficiency of 25.25%. This represents a substantial efficiency enhancement of nearly 7% compared to standalone Silicon cells. The study underscores the significance of design optimization in maximizing performance. The energy band diagram analysis reveals a strong correlation with the I-V characteristics, providing valuable insights into solar cell performance under varied optical injections. Notably, the Xenon light source exhibits a higher deviation of the quasi- Fermi level, resulting in increased current density surpassing the AM1.5G conditions by approximately 2.5 mA/cm2. These findings underscore the promising potential of PSSTC for highly efficient indoor solar energy conversion and emphasize the critical role of design optimization in unlocking peak performance.
