Liquid tin-sulfur compound shows thermoelectric potential

June 13, 2017

MIT researchers have developed a liquid thermoelectric device with a molten compound of tin and sulfur that can efficiently convert waste heat to electricity, opening the way to affordably transforming waste heat to power at high temperatures.

Left to right: Cooper Rinzler PhD '17, graduate student Youyang Zhao, and MIT Assistant Professor Antoine Allanore developed new formulas for predicting which molten compounds will be semiconducting and built a high-temperature thermoelectric device to produce electricity from molten semiconducting compounds that could reuse industrial waste heat.
