ABSTRACT:
A solar cell is provided which utilizes a semicrystalline semiconductor starting material. The solar cell has a metallic layer deposited over the grain boundaries between adjacent active grain areas of the material to collect the current generated in the grain areas. The metallic layer also shields the grain boundaries from illumination, thereby passivating the boundaries.
