Attempts to generate heat and electricity with the same collector have so far not had much success. The reason is that the efficiency of silicon solar cells drops with increasing temperature. A hybrid collector based on a luminescent concentrator/collector within a thermal collector is proposed. In this manner the solar cell is operated outside the collector at lower temperature. Electrical and thermal conversion can be optimized separately.
