Wechat Abstract Electrochemical corrosion effects can occur in thin-film photovoltaic (PV) modules that are fabricated on tin-oxide-coated glass when operating at high voltages and at elevated temperatures in a humid climate.
The corrosion of thin film modules is a known reliability problem, which occurs when modules are biased electrically negative towards ground in warm and humid areas. Modules that are critical in respect to TCO corrosion are currently restricted to certain inverter topologies and to dry climates.
In the case of solar cells, corrosion can occur in several compo-nents, including the metal contacts, interconnects, and pro-tective coatings. Corrosion mechanisms commonly observed in solar cells include galvanic corrosion, crevice corrosion, pitting corrosion, and stress corrosion cracking [77–127].
Over time, these cells lead to corrosion, causing pitting, etching, or general material deterioration. Electrochemical corrosion can significantly reduce solar cell’s light absorption and energy conversion efficiency, impacting the overall performance of PV modules.
