HIGH VOLTAGE SOLAR CELL ARRAY SEGMENT.

This report covers the progress on the High Voltage Solar Cell Array Segment. The internal integrated isolation and interconnection design was used in fabrication of HVSC on silicon web. A series connected array of four uncoated units, not necessarily adjoining one with the other, yielded an integrated output of Voc 2.0 volts and 5.5 efficiency under 100 mwcm squared incident tungsten lamp radiation. The curve factor was 0.76. Problems encountered were similar to those experienced on equivalent arrays fabricated on silicon wafers. Thus, feasibility of the design concept has been demonstrated on silicon web. Size and weight of the multiplier portion of the converter were reduced by a factor of five by using subminiature components. Chopper operation has been demonstrated at a frequency of 1 mHz. Finally, the development of a voltage controlled oscillator for voltage regulation has been initiated. Author
