Enhancing solar cells with heat

November 7, 2013

Thermophotovoltaic system converts high heat to narrow spectrum tailored to solar cell profile


Cross-sectional view of an operating solar thermophotovoltaic (STPV) device shows the glowing side of the absorber/emitter substrate. By using photonic crystals and controlling absorption and emission wavelengths, Andrej Lenert and colleagues at MIT were able to maximize heat to electric conversion and minimize energy loss.
