Water leakage inside the photovoltaic panel
The presence of moisture (inside or outside the PV module) together with high temperature and UV radiation can lead to delamination and discolouration of encapsulants, PID, corrosion of metal contacts, optical loss, solar cell degradation, adhesion loss, and other related material degradation culminating into PV module degradation and loss in .

The toxicity of CdTe PV solar cells (Morgan et al., 1997; Zayed and Philippe, 2009; Tammaro et al., 2016) has been reported for rats, bacteria, water fleas, and green algae. Two toxicity studies on rats used CdTe reagents and one ecotoxicity study used leachates after fragmentation and pure water treatment.
These results clearly demonstrate that the CER layer can effectively prevent lead leakage from damaged perovskite mini-modules. We then dripped water onto the damaged solar mini-modules without.
This strategy was able to prevent water from penetrating the damaged perovskite solar modules and reduce the Pb leakage rate by 375 times compared with using ultraviolet-cured resins for .
This paper analyzes the mechanisms for corrosion and delamination observed in Si photovoltaic modules subjected to high temperature and humidity with a negative-ground bias testing. Based on the thermodynamic data, the ionic component of the leakage current causes reduction reactions of water on the cathodic metallization, producing hydrogen .
