Abstract
The photovoltaic device is provided with a photovoltaic element on the surface of a substrate, and a light diffuse transmission filter, which diffuses light passing through it, over the surface of the photovoltaic element. The light diffuse transmission filter is separated from the surface of the photovoltaic element via spacers or via a light transmitting gap layer.
Claims21
A photovoltaic device comprising:
- (a) a substrate;
- (b) a photovoltaic element, without a transparent resin layer, provided on a surface of said substrate;
- (c) a light diffuse transmission filter for diffusing light passing therethrough, said light diffuse transmission filter being disposed over a surface of said photovoltaic element;
- and
- (d) a plurality of spacers disposed between said photovoltaic element and said light diffuse transmission filter such that the surface of said photovoltaic element is separated from an opposing surface of said light diffuse transmission filter.
