Performance evaluation of a spectrum splitting type hybrid photovoltaic/thermal collector

This study proposes a spectrum splitting type hybrid photovoltaic/thermal collector system as a method of suppressing an increase in the temperature of the solar cell to improve power generation efficiency. Infrared radiation, which does not contribute to the power generation in the solar cell, is separated from the solar light before irradiated to the solar cell, and used for the power generation by heat engine. It was shown by experiment and numerical calculation that the power generation efficiency of the system can be improved by the effect of the decrease in temperature of solar cell.
