Integrated photovoltaic generator

摘要

Disclosed is an integrated photovoltaic generator containing a plurality of photovoltaic cells, the generator capable of producing a voltage greater than that generated by a single photovoltaic cell of comparable chemical composition. The generator comprises a wafer of semiconductor material having two major surfaces, at least one of the major surfaces including a plurality of discrete areas containing an impurity of one type of conductivity, at least the portion of the remainder of the wafer contiguous to the areas containing an impurity of an opposite conductivity type, and electrical conductor means between at least one area and the portion of the wafer containing the impurity of the opposite conductivity type.
