Abstract
A thin film photovoltaic device comprising a relief textured transparent cover plate, a layer of transparent conductive oxide having a layer thickness of less than 700 nm, a light absorbing active layer and a reflective back electrode, where the layer of transparent conductive oxide is a non-textured layer.
Claims10
A thin film photovoltaic device comprising:
- a relief textured transparent cover plate,
- a layer of transparent conductive oxide having a layer thickness of less than 700 nm,
- a light absorbing active layer, and
- a reflective back electrode,
- wherein
- the layer of transparent conductive oxide is a non-textured layer, and
- the transparent cover plate is relief structured by comprising an array of geometrical optical relief structures containing a base, an apex and a set of surfaces, wherein the surfaces connect the base to the apex, and the surfaces are at least three n-polygonal surfaces where n is equal to 4 or higher.
