Patent ID: 8906257

Claim:
A photovoltaic panel comprising: at least one photovoltaic element; a lower support and an upper support; and a composite getter comprising a H 2 O sorber dispersed in a polymeric matrix, characterized in that said H 2 O sorber consists essentially of between 20 and 50% by weight of one or more alkaline earth metal oxide and said polymeric matrix has a H 2 O transmission lower than 10 g mm m 2 d −1 at 25° C. and 60% relative humidity and the material forming said polymer is chosen among Ethyl Vinyl Acetate (EVA) and Ethylene-Propylene Rubbers (EPR) and wherein said photovoltaic panel is delimited by said lower support, said upper support and by said composite getter, and said photovoltaic panel comprises a polymeric material, different from said composite getter, filling an inner volume of the photovoltaic panel and encapsulating said at least one photovoltaic element.
