Abstract

This paper investigated the effect of thermally assisted light soaking （TALS） on the performance of amorphous/crystalline silicon heterojunction （SHJ） solar cells. The experimental results confirm that light soaking （LS） effectively improves the power conversion efficiency and fill factor of SHJ solar cells by 0.23% and 0.91%

while TALS increases the gain to 0.34% and 0.98%. By measuring the dark electric conductivity of doped amorphous silicon films before and after the TALS

it is found that TALS has more significant effect on improving the electrical properties of the films compared to LS

enabling n-type amorphous silicon thin film dark electric conductivity gain ratio of 9.05. Combined with Sinton WCT-120 and Suns-V measurements

it is concluded that TALS improves the field passivation performance

enhancing the built-in electric field strength of crystalline silicon and amorphous silicon heterojunction

thus reduces the recombination of minority carriers at the interface

resulting in a light-induced gain of 0.34% in the output performance of SHJ solar cells.
