Abstract Copper plating features in the ITRPV roadmap but there is little published work in the scientific literature on the degradation mechanisms and the interaction with module encapsulant. Under this proposal we evaluate the reliability of copper plated cells within a module for two modern architectures PERC cells and silicon heterojunction solar cells.
