OPTICAL STRUCTURE WITH A FLAT APEX

A photovoltaic device having at least one active layer and a cover plate that contains on one side an array of optical structures and that is in optical contact with the light receiving surface of the active layer(s) in order to reduce the reflection losses of the surface. The plate or sheet may als...

More Information
Summary:A photovoltaic device having at least one active layer and a cover plate that contains on one side an array of optical structures and that is in optical contact with the light receiving surface of the active layer(s) in order to reduce the reflection losses of the surface. The plate or sheet may also be used in combination with luminescent molecules, which are inside or in contact with the plate, to improve the spectral response of the photovoltaic device. The optical relief structures having a base and a single flat apex that are connected by at least three n-polygonal surfaces where n is equal to 5 or higher.
