Boosting PERC Solar Cell Output

Abstract

By limiting recombination, passivated emitter and rear cell (PERC) solar cells can provide an absolute efficiency boost of 1%, making their relative efficiency about 7% greater than that of other screen printing methods. This article covers the early stages of the nondestructive and destructive imaging performed to evaluate and enhance the efficiency of PERC solar cells. Electroluminescence images, acoustic images, and scanning electron micrographs were used in this research.
