Abstract

A laminate film includes a plurality of planar photovoltaic semi-transparent modules disposed one on top of another and laminated to each other. Each of the modules includes a substrate, first and second conductive layers and at least first and second semiconductor layers disposed between the conductive layers. The first and second semiconductor layers define a junction at an interface therebetween. At least one of the junctions is configured to convert a first spectral portion of optical energy into an electrical voltage and transmit a second spectral portion of optical energy to another of the junctions that is configured to convert at least a portion of the second spectral portion of optical energy into an electrical voltage.
