Electrochemical and galvanic corrosion effects in thin-film photovoltaic modules

Abstract
The electrochemical and galvanic corrosion properties of thin-film photovoltaic (TF-PV) modules (solar cells) and module subcomponents are determined and interpreted in the light of established corrosion science. Results of a detailed study of thin-film aluminum metallization corrosion are presented. Bar-graph corrosion, observed in fielded modules, has been induced experimentally and found to be electrochemical in nature. Corrosion rates and passivation techniques for TF-PV modules are discussed.<>
