Patent ID: 8012855

Claim:
A method for forming a solar cell comprising a plurality of tile structures, the method comprising: providing two or more separate tiled donor substrates, each of the tiled donor substrates being characterized by a donor substrate thickness and a donor substrate surface region having a surface area corresponding to an entire processed semiconductor substrate; concurrently implanting particles through the donor substrate surface region of each of the separate tiled donor substrates, to form a respective cleave region between a portion of the donor substrate thickness and the donor substrate surface region in each of the two or more separate tiled donor substrates; joining each of the donor substrate surface regions to a handle substrate surface region of a handle substrate; separating along a cleave plane of the cleave region of each of the tiled donor substrates, a respective tiled donor substrate portion spatially disposed overlying the handle substrate surface region; and incorporating the plurality of tiled donor substrate portions into a solar cell structure offering a sufficient photovoltaic surface area to convert solar energy into electrical power.
