Warfield, D B

This patent describes an improved vertical junction solar cell. It comprises: a silicon semiconductor body having a front surface; parallel grooves formed ins aid front surface of the body and disposed normal to the front surface, the grooves defining a corresponding walls each having a top surface and side surfaces and groove bottoms between adjacent ones of the walls at least one photoro Haic junction extending along the side and top surface of the walls; and focusing coverslide means for focusing incident light impinging the solar cell onto the top surfaces of the walls and away from the groove bottoms to thereby reduce radiation degradation of the solar cell.
