PHOTOVOLTAIC DEVICE AND METHOD FOR ENCAPSULATING
First Claim
1. A photovoltaic device comprising a thin-film photovoltaic layer between a substrate and a cover plate, which cover plate is transparent in an area above the photovoltaic layer, wherein the cover plate overlaps the photovoltaic layer, and wherein the cover plate, in an area adjacent to the photovoltaic layer, is opaque, wherein the cover plate is coated in the opaque area, on at least one side facing towards the substrate, or has a modified body so as to be opaque in that area.

Abstract
A photovoltaic device comprising a photovoltaic layer between a substrate and a cover plate, which cover plate is transparent in an area above the photovoltaic layer, wherein the cover plate overlaps the photovoltaic layer, and wherein the cover, in an area adjacent to the photovoltaic layer, is opaque; a method of encapsulating a photovoltaic device with such a cover plate, and the use of such a cover plate for encapsulating a photovoltaic device, for protecting polymeric sealant material present adjacent the photovoltaic layer from light induced degradation and/or for protecting the encapsulated photovoltaic device from thermal stress during due to light irradiation.

11. A method of encapsulating a photovoltaic device, comprising the steps of
providing a substrate having an area with a thin-film photovoltaic layer on a partial area of the substrate, providing a cover plate having a transparent area and an opaque area adjacent the transparent area; - and
arranging the cover plate over the photovoltaic layer, so that the opaque area covers at least part of the substrate area outside the partial area on which the photovoltaic layer is arranged. - View Dependent Claims (12, 13, 14, 19)
