FIELD: chemistry.
SUBSTANCE: photovoltaic module contains: a laminate of a) a transparent front covering, b) one or more photosensitive semiconductor layers, c) at least one plasticiser-containing film based on polyvinyl acetal with polyvinyl alcohol content of more than 12 wt %, and d) a back covering. The module is characterised by that plasticiser-containing films c) based on polyvinyl acetal have glass-transition temperature Tg of at least 20°C. The invention also relates to use of the films based on polyvinyl acetal with content of polyvinyl alcohol of more than 12 wt %, having glass-transition temperature Tg of at least 20°C for filling cavities present in photosensitive semiconductor layers or electrical connections thereof when manufacturing photovoltaic modules.
EFFECT: films with said glass-transition temperature have high specific resistance.
