Solar thermophotovoltaic system with high temperature tungsten emitter

In this paper, R&D of a solar thermophotovoltaic (STPV) system is reported. Two types of TPV modules have been developed and tested under concentrated sunlight. Temperatures as high as 1800/spl deg/C were obtained in a 12 mm dia and 15 mm length emitter, illuminated by a 0.45 m/sup 2/ pseudoparabolic facet mirror with a secondary quartz lens (4000/spl times/ concentration ratio). Analysis of various parameters, influencing the overall performance of the developed STPV is presented.
