3 · 1 Introduction. Hydrogen is found to enhance the performance of silicon (Si) solar cells by passivating defects in the bulk and at the surface. [] Regarding bulk defects, hydrogen passivation is particularly crucial for multicrystalline (mc) silicon material, [] as well as for passivating the boron–oxygen defect. [] Additionally, hydrogen can passivate bulk …
LeTID can degrade the performance of PERC solar cells by up to 10%. The exact reason behind this temperature-dependent LID in PERC solar cells is still unknown but it is believed that LeTID might occur due to the degradation of dielectric passivation layers. LeTID is also speculated to occur as a result of bulk recombination …
