[10a-N104-4] Tolerance to hygrothermal stress for thin-film Si photovoltaic modules using polyvinyl butyral encapsulants
Keywords:photovoltaic modules, polyvinyl butyral, thin-film silicon
Retention of output power for thin-film Si photovoltaic modules above 85% was kept after damp-heat test for 50000 h if using polyvinyl butyral (PVB) encapsulants instead of ethylene vinyl acetate (EVA) encapsulants.
