Claim Text:
1. A device with integrated photovoltaic cells, comprising: a continuous semiconductor substrate including doped alternating regions with opposite conductivity and non-doped regions formed between each of the doped alternating regions; at least one doped layer formed over a first side of the semiconductor substrate; and a patterned conductive material formed over the at least one doped layer forming first conductive islands such that the first conductive islands are aligned with the alternating regions to define a plurality of photovoltaic cells connected in series on a monolithic structure; at least one other doped layer formed on a second side of the continuous semiconductor substrate, opposite the first side; and second conductive islands formed over the at least one other doped layer and aligned with the alternating regions of opposite conductivity to further define the plurality of photovoltaic cells connected in series to the monolithic structure.
