Comprehensive Simulation Parameters and Layer Configurations of ZnTe-Perovskite, Perovskite-CIGS/GaAs, and Perovskite-CIGS/Si Tandem Solar Cell Models Analyzed Using SCAPS Software

This study investigates the performance potential of three tandem solar cell configurations—ZnTe-Perovskite, Perovskite-CIGS/GaAs, and Perovskite-CIGS/Si—through detailed numerical simulations using SCAPS-1D. The research is based on the hypothesis that optimized material combinations and interface engineering in tandem structures can significantly enhance photovoltaic efficiency. Each model was constructed using carefully selected layer parameters, including thickness, bandgap, electron affinity, doping levels, and carrier mobilities, derived from literature and adjusted for simulation stability. The data reveals that the Perovskite-CIGS/GaAs tandem exhibited the highest simulated efficiency due to excellent band alignment and low recombination losses, while the Perovskite-CIGS/Si model showed promising thermal stability and manufacturing potential. These findings underscore the critical role of interface properties and layer configuration in tandem cell performance. The parameter tables provided can be directly used for further simulation, sensitivity analysis, or optimization studies by researchers working on advanced photovoltaic technologies.
