Parameter optimization of silicon solar cell back surface field (BSF) formation

Abstract

The BSF of mono-crystal silicon cell is studied in this paper. It simply states the principle and formation process of BSF, and studies the evenness of BSF. In the experiment, we analyze BSF formed by taking different sintering temperature, heating rate and setting different time, develop by chemical reagent and observe at high magnification scope, analyze and get the optimal parameters of forming even BSF and further improve conversion efficiency of silicon chips.
