The thermoradiative cell is a new concept for converting heat energy into electrical power, using solid-state physics principles similar to the operation of a photovoltaic cell. The technology has possible application for radioisotope power conversion for space applications, but to date most of the theoretical analyzes looked only at ideal performance, and the real-world efficiency loss mechanisms are not well understood, in particular, the loss of energy to infrared emissivity.
Desired is research on understanding and improving the efficiency of thermoradiative cell technology, including understanding the losses under real-world conditions.
