Transferability of the Light-Soaking Benefits on Silicon Heterojunction Cells to Module

We investigate the effect of light soaking and forward electric bias treatment on silicon heterojunction solar cells modules and, in particular, influence thermal occurring during lamination. A substantial performance increase is observed after or soaking, which shown to be potentially partly reset by lamination process. This reproduced annealing with same budget. second again improves performances, a similar final reached independently prelamination treatment. Therefore, single enables maximal module output no benefit from cell pretreatment. Whereas react overall better bias, show slightly response soaking.
