20130026593 | THIN FILM PHOTOVOLTAIC DEVICE WITH ENHANCED LIGHT TRAPPING SCHEME - 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. | 01-31-2013 |
20120204953 | 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 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. | 08-16-2012 |
