Abstract

This paper fabricated industrially-sized crystalline silicon heterojunction （HJT） solar cells and investigated the effect of light injection on the optoelectronic performance of the cells. The experimental results demonstrate that light injection effectively enhances the photovoltaic conversion efficiency of HJT solar cells. After light injection, the absolute improvement in the photovoltaic conversion efficiency of the cells reaches 0.33%. Combined with the I-V test under simulated illumination and Suns-V_oc test, it is confirmed that the light injection can reduce the series resistance of the cell. Therefore, the main physical mechanism of enhanced cell performance is attributed to the reduction in series resistance by light injection.

Key words
