Abstract:

During this contract thin-film GaAs solar cells using semitransparent Pt layers as the barrier contact have been made and investigated to improve their photovoltaic characteristics. Studies of the GaAs film, grown by the oxide transport process, and the barrier contact structure, consisting of the Pt film, gridding, and antireflection coating, led to the fabrication of a cell of 2-sq cm active area with an efficiency of 3.77 percent under tungsten light giving an Isc value equivalent to that of 1100 mW sq cm air mass 1 sunlight. The cell fabrication methods which were developed resulted in cells that exhibited no degradation under room ambient. Author
