ABSTRACT:
This invention provides a bifacial photovoltaic device to enhance the conversion of solar energy into electricity with a layer by layer additive structure. The bifacial photovoltaic device comprises an electrically conductive core electrode, a plurality of semiconductor layers covering one end region of the core electrode and at least a portion of the two faces of the core electrode, a first counter electrode, a second counter electrode, and a third counter electrode connecting the first and the second counter electrodes. The device may also comprise a light reflective layer and an anti-reflective layer. This invention also provides an array of bifacial photovoltaic cells with simple interconnection schemes.
