Water ingress into photovoltaic panel packaging
Many thin film PV technologies are sensitive to moisture requiring the use of packaging schemes that prevent or reduce moisture over a 25 y expected product lifetime. This is easily accomplished using a glass frontsheet, with an impermeable backsheet and polyisobutylene based. . versary to hermetic packaging. However, at present, there exist no solutions for extremely water-sensitive mater als for flexible applications. By using diffu-sivity measurements for water through encapsulants such as ethylene vinyl acetate (EVA), we have modeled mois-ture ingress using a. .
