Abstract
The field of thermophotovoltaics offers a direct method to translate the heat generated as a byproduct of other standard energy generation techniques into usable electricity. This requires an emitted spectrum tailored to produce the maximum possible amount of light in a wavelength regime which is utilizable by a given photovoltaic cell. In this work, we investigate the efficiency of coating/substrate emitters using ~50 materials with melting points >2000C. We show combinations including oxide/refractory metal coating/substrate pairs which result in an FOM of >40% at 1800C, demonstrating their potential to greatly outperform currently available thermophotovoltaic devices.
