Abstract
A photovoltaic device including an active layer of an amorphous material in which the active layer is in the shape of an array of defined and repeating geometrical structures, wherein the geometrical structures include a base and a single apex that are connected by at least three n-polygonal surfaces where n is equal to 4 or higher.
Claims15
A photovoltaic device of the thin film type, comprising
- an active layer that is in a shape of an array of defined and repeating geometrical structures,
- wherein each geometrical structure comprises a base and a single point apex, the single point apex and the base being connected by at least three n-polygonal surfaces, wherein n represents the number of sides of each polygonal surface and is equal to 4 or higher.
A method for producing a photovoltaic device of the thin-film type in which an active layer is in a shape of an array of defined and repeating geometrical structures, the method comprising:
- providing a supporting substrate with two main surface sides,
- shaping a surface side of the two main surface sides of the supporting substrate into a shape or into an inverse shape of the defined and repeating geometrical structures of the active layer, and
- applying the active layer onto the surface side of supporting substrate, wherein each geometrical structure comprises a base and a single point apex, the single point apex and the base being connected by at least three n-polygonal surfaces, wherein n represents the number of sides of each polygonal surface and is equal to 4 or higher, wherein the two main surface sides of the supporting substrate are parallel to a general plane of the active layer.
