Abstract

To investigate the influence of the difference in module structures on the degradation of crystalline silicon solar cells, two different photovoltaic modules were fabricated, and a high-temperature and high-humidity test was carried out. The degradation modes of these modules were compared to each other using electrical characteristics and electroluminescence images. Degradation of outputs occurred in both modules, and different degradation modes were confirmed by electroluminescence images. The difference in degradation modes between these modular structures could be due to the difference in concentration distribution attributable to the moisture and acetic acid generated from the encapsulant inside the module.
