Abstract:
1. A planar bifacial photovoltaic device to absorb lights coming from either side comprises: an electrically conductive planar core electrode sheet with a first face, a second face, a first end region and a second end region; a plurality of semiconductor layers covering said second end region and at least a portion of said first face and at least a portion of said second face, exposing said first end region of said planar core electrode sheet, said plurality if semiconductor layers including first semiconductor layers on said first face and second semiconductor layers on said second face and third semiconductor layers on said second end region of said planar core electrode sheet; a first counter electrode for current collection on said first semiconductor layers; a second counter electrode for current collection on said second semiconductor layers; and a third counter electrode on said third semiconductor layers electrically connecting said first counter electrode and said second counter electrode, said third counter electrode having a first face and a second face.
