Patent ID: 7674687

Claim:
A method for forming a solar cell comprising a plurality of tile structures on a substrate member, the method comprising: providing a transfer substrate, the transfer substrate having a surface region, the surface region supporting a plurality of separate tiled donor substrates, each of the tiled donor substrates being characterized by a tile edge, a donor substrate thickness and a donor substrate surface region having a surface area corresponding to an entire processed semiconductor substrate, each of the tiled donor substrates being spatially disposed overlying the surface region of the transfer substrate; implanting a plurality of particles concurrently through two or more of the donor substrate surface regions supported on the transfer substrate to form a cleave region provided by the plurality of particles between a portion of the donor substrate thickness and the donor substrate surface region for the two or more tiled donor substrates; and joining each of the donor substrate surface regions to a handle substrate surface region, the handle substrate surface region being provided from a handle substrate; removing the transfer substrate from the handle substrate to separate along a cleave plane of the cleave region, a plurality of tiled donor substrate portions 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.
