Proton damage in silicon solar cells can be normalised to the damage producedby protons of one energy. The proton energy employed for normalisation ofrelative damage should be close to that producing maximum damage in spaceenvironments, produce relatively uniform damage, and be available forlaboratory evaluations.
UV-induced degradation (UVID) poses a serious concern in silicon heterojunction (SHJ) solar cells when operating in the field. Herein, the root cause of UVID of bare SHJ solar cells was investigated. It was found that the major degradation occurs in open-circuit voltage (Voc) and fill factor (FF) during UV exposure.
Based on this phenomenon, the mechanism of UVID in SHJ solar cells is investigated systematically. Firstly, the PL images indicate additional defects induced by UV irradiation in SHJ solar cells. Furthermore, we investigate localized defects in a -Si:H from the analysis of carrier transport mechanism.
The major degradation of SHJ solar cells without encapsulation occurs in open-circuit voltage (Voc) and fill factor (FF) during UV exposure. The pore structure forming in silicon layers are attributed to the decreasing of hydrogen passivation on silicon surface.
