|Energy generation from heat with a solar cell built backwards|
cells absorb incoming sunlight and convert a part of photon energy into
electricity. The remainder of photon energy is dissipated as heat.
Although the idea is rather counter-intuitive, 'reverse solar cell'
systems can also generate electric power by emitting rather than
absorbing photons. Such systems - known as thermoradiative cells -
generate voltage and electric power via non-equilibrium thermal
radiation of infrared photons. Thermoradiative cells offer an
opportunity to generate clean energy by harvesting radiation from
largely untapped terrestrial thermal emission sources, potentially
including the Earth itself.
