Design Optimization and Characterization of High Efficiency Pert Crystalline Silicon Solar Cell by Numerical Simulation

Abstract

This research uses numerical simulations to optimize PERT crystalline silicon solar cells, investigating monofacial and bifacial configurations. Leveraging the PC1D simulation tool in conjunction with practical device configurations, this project involves designing and fine-tuning critical solar cell components, including the absorber, emitter, and back surface layers, with meticulous attention to doping levels, layer thicknesses, and carrier recombination mechanisms. newlineA crucial aspect of enhancing solar cell efficiency is altering the electrical and physical properties of the silicon semiconductor. The research examines the impact of surface texturization and anti-reflective coatings to reduce reflectance losses and improve light absorption. It also involves analyzing the electrical performance of bifacial solar cells using various characterization methods. According to the research s key findings, a carefully selected configuration can greatly improve efficiency. For optimal results, a 200 and#956;m thick p-type single-crystalline silicon wafer with 3 and#937;.cm resistivity, combined with n+ emitter doping intensity of 1x1018 cm-3 and a p+ Back Surface Field (BSF) doping intensity of 1x1019 cm-3, can result in efficiencies of 22.56% for monofacial cells and 27.51% for bifacial cells. The key to achieving optimal efficiency is to keep the front and back surface recombination velocities between 10 and 100 cm/s newline
