A team of researchers in the US (Laurence Berkeley National Laboratory, UCBerkeley, National Renewable Energy Laboratory, Swarthmore College, University of Colorado, Caltech) used the rear mirror to create thermophotovoltaic systems with unprecedented high thermophotovoltaic efficiency. This mirror reflects low-energy infrared photons back into the heat source, recovering their energy. Therefore, the rear mirror serves a dual function; boosting the voltage and reusing infrared thermal photons. This allows the possibility of a practical >50% efficient thermophotovoltaic system…read more. Open Access TECHNICAL ARTICLE
