ABSTRACT:
A hybrid solar energy generating system for effectively utilizing the total solar spectrum gathered by a solar ray concentrator. The system includes a first solar ray receiver having fluid-cooled photovoltaic solar cells for generating electricity and low-temperature heat. A second solar ray receiver is provided for generating high-temperature heat. A lens focuses the solar rays on the first receiver. A selective transmitting heat-mirror is positioned between the lens and the first solar ray receiver for reflecting selected portions of the solar ray spectrum to the second solar ray receiver and passing essentially the remaining solar ray spectrum to the first solar ray receiver. The heat-mirror reflects all solar rays having wavelengths longer than the long-wave spectral response cut-off of the photovoltaic solar cells and a selected part of the solar rays having wavelengths shorter than the long-wave spectral response cut-off. The heat-mirror spectral profile shape is modified to maximize the conversion of solar energy to high-temperature heat while causing only a minimal decrease in the generation of photovoltaic electricity.
