ABSTRACT:
A photovoltaic microarray such as a solar cell array is monolithically fabricated, without a supporting substrate, by forming a network of trenches from one side of a substrate to define separate cell areas, filling the trenches with an insulative filler material that adheres to the substrate material and provides structural integrity, and then trenching from the opposite side of the substrate to provide an air gap insulation network between adjacent cells. Series connections are provided between adjacent cells by connecting the front surface of one cell over the filler material to the bulk semiconductor for the next cell, with the connection completed through the bulk semiconductor itself to back electrodes for each cell.
