Abstract

Each of a plurality of solar cells is disposed on a base member made from an electrically insulating material. Each of the solar cells has first and second cell portions separated by an insulating gap, the first cell portion being positive and the second portion being negative. A third cell portion may be provided in each solar cell with the first portion being disposed between, and in insulated relationship to, the second and third portions and with the third portion being negative. Each of the solar cells may include a positive termination extending from the first cell portion and a negative termination extending from the second (and third) cell portion(s) and separated from the first cell portion by an insulating gap. Each of a plurality of diodes is disposed on an individual one of the base members across the insulating gap between the positive and negative terminations of an individual one of the solar cells on the base member. Each of the diodes includes a cathode disposed on the positive termination of the individual one of the base members in electrical continuity with such positive termination and includes an anode disposed on the negative termination of the individual one…
