U.S. scientists have developed a thermophovoltaic cell that could be paired with inexpensive thermal storage to provide power on demand. The indium gallium arsenide (InGaAs) thermophovoltaic cell absorbs most of the in-band radiation to generate electricity, while serving as a nearly perfect mirror.
Closing in on the theoretical maximum efficiency, devices for turning heat into electricity are edging closer to being practical for use on the grid, according to University of Michigan research.
