  • Heterocontact Solar Cell with Inverted Geometry of its Layer Structure
    Publication number: 20080156370
    Abstract: A heterocontact solar cell in a layer structure. The solar cell includes an absorber made of a p-type and/or n-type doped crystalline semiconductor material. The cell also includes an emitter made of an amorphous semiconductor material that is oppositely doped relative to the absorber. Also included is an intrinsic interlayer made of an amorphous semiconductor material between the absorber and the emitter. The cell includes a cover layer on the side of the absorber facing a light. A first ohmic contact structure including a minimized shading surface on the side of the absorber facing the light and a second ohmic contact structure on a side of the absorber facing away from the light are also included.
