Photovoltaic device having polycrystalline base
First Claim
1. A photovoltaic device comprising a photoresponsive polycrystalline base having individual crystallites, said base having at least one substantially flat surface to which illumination is to be applied, and an electrically conductive grid affixed to said flat surface, said grid being arranged so that substantially all of the individual crystallites are contacted at least once by said grid, said grid being constructed of a material that will effect a rectifying junction with said base, said base having ohmic electrical contact means affixed thereto at a point spaced from said grid.

Abstract
A photovoltaic device comprising a polycrystalline base having an electrically conductive grid affixed to the surface of the device to which illumination is to be applied, said grid effecting a rectifying junction with the base and at the same time functioning as a current carrying contact, said grid being arranged so that substantially all of the individual crystallites are contacted at least once thereby, while at the same time maintaining the coverage of the base by said grid to a minimum.
