Solarzelle und Verfahren zu deren Herstellung

DE 102009029944 A1 UPAB: 20110106 NOVELTY - The cell has a silicon substrate (1), a rear side (3), and a front side (2) that is formed for light coupling. The front and rear sides exhibit front side and rear side textures in sub-areas, where the textures are cyclic along spatial directions (A, B) with a period length larger and smaller than 1 micrometer, respectively. One of the spatial directions stays at an angle between 80 and 100 degrees to the other spatial direction. A rear side layer i.e. dielectric layer, is attached to the rear side, where the rear side texture is completely covered by the dielectric layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a solar cell. USE - Semiconductor-silicon solar cell for converting electromagnetic radiation into electrical energy. ADVANTAGE - The solar cell is designed in such a manner that the light efficiency is increased even with long-wave radiation
