STUDY OF A THERMOPHOTOVOLTAIC CONVERTER.
Abstract
Materials and components for a thermophotovoltaic converter were studied theoretically and experimentally. Germanium photovoltaic cells were tested at output power-densities ranging up to 1.9 watts/sq cm under high illumination levels; grid design calculations were carried out on the basis of these measurements. Techniques were developed for mounting high power-density, opticallyaligned photocells on a cylindrical cooling jacket. Two semi-conductor materials were examined as possible alternatives to germanium. Preliminary data are included on the reflectivity of emission enhancement coatings on a ceramic substrate; experiments were performed to determine the life of a new diffusion coating on a metallic substrate.
