Abstract:
A solar cell includes polysilicon P-type and N-type doped regions on a backside of a substrate, such as a silicon wafer. A trench structure separates the P-type doped region from the N-type doped region. Each of the P-type and N-type doped regions may be formed over a thin dielectric layer. The trench structure may include a textured surface for increased solar radiation collection. Among other advantages, the resulting structure increases efficiency by providing isolation between adjacent P-type and N-type doped regions, thereby preventing recombination in a space charge region where the doped regions would have touched.

Claim (Index 1):
A solar cell comprising:\n a first dielectric layer disposed on a back side of the substrate, wherein the substrate has a front side opposite the back side; and a first doped polysilicon region and second doped polysilicon region disposed on the first dielectric layer, wherein the first doped polysilicon region is physically separated from the second doped polysilicon region.
