Abstract:

Results are presented of a basic research project in two phases to determine feasibility of solar thermoelec ric generators outside of the earths atmosphere. It was concluded that simultaneous solutions of two problems are required 1 Solar energy collection and he t sink radiation efficiency must be as high as possible to obtain the widest possible temperature difference between the hot and cold junctions of the thermoelectric generator. Using selective absorbing and radiating surfaces on flat-plate collectors, and 10- to 20-fold concentrating collectors, a temperature difference of 200 to 520 C can be reached with a collection efficiency in excess of 50 and 2 Thermoelectric efficiency with materials presently available can reach 9 efficiency with a factor of merit Z 0.002 per C. With Z 0.004, an efficiency of 19 could be att ined at 500 C temperature difference. Flatplate and oriented concentrating collectors ar also iscu s d. Author
