ABSTRACT:
Solar cell for use in a concentrator having a body formed essentially of silicon doped with a P-type impurity and having a base resistivity ranging from 0.5 to 1.5 ohm-centimeter and having back and front side planar surfaces. A layer of aluminum is formed on the back side surface and is alloyed into the silicon body to form a P-plus layer extending through the back side surface. An N+ layer is formed in the silicon body and extends through the front side surface. A multi-layer metal contact structure is secured by the backside and makes a P-type contact. A multi-layer metal contact structure is carried by the front side surface and makes an N-type contact. The multi-layer contact structure carried by the front side surface is formed into a grid line pattern with the grid line pattern being characterized by first and second common bus bars extending substantially through 360.degree. on said surface and being spaced at different distances from the center of the front side surfaces.
