Abstract
In order to analyze the efficiency loss of Passivated Emitter Rear Contact (PERC) cells at 23.2%, specialized samples were manufactured on the same production line to conduct a comprehensive analysis of optical, recombination, and resistance losses. The findings were then integrated into Quokka2 simulation software to model the cell's performance. The simulated results closely matched the experimental electrical performance data. The analysis revealed that optical losses were primarily attributed to near-infrared (NIR) parasitic absorption, front surface escape, and gridline shading. The most significant recombination losses were found in metal recombination and the laser doping region. Single-variable simulations indicated that optimizing the diffusion region recombination had the most substantial impact on improving cell efficiency. The main focus is to provide, from an industrial production perspective, a correct, simple, fast, and easy-to-operate method for analyzing efficiency losses of solar cells.
