Harnessing the Full Potential of the Sun
Researchers at MIT have developed a solar thermophotovoltaic device (STPV) that experimentally demonstrates a three-fold increase in energy conversion efficiency. Their device builds upon solar thermophotovoltaic technologies, adding a nanophotonic absorber-emitter that is tuned for optimal collection of sunlight and thermal emission above the photovoltaic band gap. This work was conducted by Evelyn Wang, Associate Professor of Mechanical Engineering, and members of her research group in collaboration with the Solid State Solar Thermal Energy Conversion Center. The research was funded by the Department of Energy EFRC program.
