Abstract
A photovoltaic device including at least one active layer and a transparent cover plate which contains on at least one side an array of geometrical optical relief structures and which is in optical contact with a surface receiving side of the at least one active layer of a photovoltaic device, characterized in that the optical relief structures include a base and a single apex which are connected by at least three n-polygonal surfaces where n is equal to 4 or higher.
Claims22
A photovoltaic device comprising:
- at least one active layer and
- a transparent cover layer that comprises on at least one side an array of geometrical optical relief structures comprised of a plurality of individual geometrical optical relief structures, the array being in optical contact with a light receiving surface of the at least one active layer of the photovoltaic device,
- wherein each individual geometrical optical relief structure of the array 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, and
- wherein the base of each individual geometrical optical relief structure of the array has an m-sided polygonal shape and each individual geometrical optical relief structure of the array has at least m+1 surfaces, m representing the number of sides of the base.
