Energy conversion system

Abstract

Abstract An energy conversion system is provided for converting thermal radiation energy into electricity. The system includes a source of thermal energy and a silicon cell spaced from the thermal energy source. A radiating solid material is positioned between and spaced from the thermal energy source and the silicon cell. The radiating solid material is capable of radiating a major portion of the heat received from the thermal energy source in the spectral band where the silicon cell shows its maximum spectral response. An interference filter is positioned between the radiating solid material and the silicon cell. The interference filter has its maximum reflectivity in the strongest emission band regions of the radiating solid material which are outside the maximum spectral response band of the silicon cell. The interference filter also has its highest transmission in the wavelength region where the silicon cell has good spectral response. This invention relates to an energy conversion system for converting thermal radiation energy to useful electrical energy.
