  • Bifacial Stack Structures for Thin-Film Photovoltaic Cells
    Publication number: 20130319502
    Abstract: In one embodiment, a photovoltaic cell comprises a transparent substrate having an exposed bottom surface for receiving light; a transparent-conducting-oxide layer positioned over the transparent substrate; a chalcogenide photovoltaic-absorber layer positioned over transparent-conducting oxide layer; and another transparent-conducting-oxide layer positioned over the photovoltaic-absorber layer, where the photovoltaic cell is operable to transmit incident light to both sides of the photovoltaic-absorber layer and to absorb incident light at both the top side and the bottom side of the photovoltaic-absorber layer.
