Commonly observed degradation in field-aged photovoltaic modules

Degradation leading to failure in photovoltaic modules follows a progression that is dependent on multiple factors, some of which interact causing degradation that is difficult to simulate in the, lab. This paper defines recently observed degradation in field-aged modules, including degradation of packaging materials, adhesional loss, degradation of interconnects, degradation due to moisture intrusion, and semiconductor device degradation. Additionally, this paper suggests that the onset And progression of degradation need to be studied to gain a more. comprehensive understanding of module degradation fates and module failures.
