The results of calculations of the performance of a planar PIN thermophotovoltaic cell are reported. A computer program has been written which allows the computation of the current-voltage characteristics of such a cell. The program allows the cell geometry, the bulk recombination rate, the mobility, the surface recombination velocity, and the input spectrum to be arbitrarily chosen. In addition to the current-voltage characteristic, the maximum operating efficiency and the internal voltage drop are computed. Optimum device dimensions are calculated for a specific set of materials parameters. The device performance is shown to be relatively insensitive to small variations in device dimensions. Experimental work leading to the fabrication of an interdigitated, planar PIN TPV cell is described. Author
