ABSTRACT:
A thermal collector of solar energy includes an elemental semiconductor material to absorb a substantial portion of the energy of solar radiation that is incident upon the material. At longer wavelengths, such material reradiates absorbed energy at a substantially reduced rate, whereby the efficiency of energy collection at high temperatures is improved. In a solar electric power plant collected heat is transferred from such collectors to a motive fluid, which drives a turbine-generator. The high operating temperature of the energy-absorbing material permits efficient conversion of the collected energy to electrical energy, while a required number of solar collectors is correspondingly reduced by the improved collection efficiency.
