Abstract : Work was devoted to the continued development and improvement of germanium photovoltaic devices for use in a thermophotovoltaic TPV converter. This effort was divided into two broad categories. The first category encompassed experimentation attempting to optimize the electrical performance of the absorptive TPV device. The ultimate goal of this task was to maximize the power generation exhibited by the anti-reflection coated, absorptive, TPV device. The second category encompassed experimentation attempting to develop the vapor phase epitaxial technique for the deposition of germanium on germanium substrates. The ultimate goal of this task is to develop the epitaxial technique for use in the deposition of thin, heavily doped P+ layers on N-type germanium substrates for the fabrication of the non-absorptive N on P+ device structure.
