Abstract
Systems, methods, devices, and products of processes consistent with the innovations herein relate to thin-film solar cells having contacts on the backside, only. In one exemplary implementation, there is provided a thin film device. Moreover, such device may comprise a substrate, and a layer of silicon or silicon-containing material positioned on a first side of the substrate, wherein the layer comprises a n-doped region and a p-doped region. In some exemplary implementations, the device may be fabricated such that the n-doped region and the p-doped region are formed on the backside surface of the layer to create an electrical structure characterized by a P-type anode and an N-type cathode forming a junction positioned along the backside surface of the layer.
