Thin-film CIGS PV modules with more than 3000 h damp heat stability: Breakthrough time property of the B-Dry ® edge sealant and its characterization

Photovoltaic cells need to have a long operative lifetime, in order to be competitive against the so-called polluting sources. In particular, thin-film technologies such as CIGS suffer from degradation due to moisture ingress into the panel. An edge sealing tape applied in addition to a standard lamination foil used in the encapsulation process can strongly reduce the moisture permeation and degradation.
