A thermophotoovoltaic cell from MIT has reached an efficiency of 40% in laboratory testing -- a record for TPVs.
More than 90% of the world’s electricity comes from sources of heat such as coal, natural gas, nuclear energy, and, the MIT announcement says. For a century, steam turbines have been the industrial standard for converting such heat sources into electricity.
“One of the advantages of solid state energy converters are that they can operate at higher temperatures with lower maintenance costs because they have no moving parts,” Henry says. “They just sit there and reliably generate electricity.” The cell is fabricated from three main regions: a high bandgap alloy, which sits over a slightly lower bandgap alloy, underneath which is a mirror-like layer of gold. The first layer captures the highest energy photons from the heat source and converts them into electricity. Lower energy photons that pass through the first layer and are converted to electricity as well.
