Thermovoltaic efficiency

WebbIn a STEG, a pair of thermoelectric legs is sandwiched between a solar absorber and a heat sink. When the solar absorber is exposed to sunlight, it heats up, causing a temperature gradient across the thermoelectric elements and current to flow. In the 1950s, STEGs with efficiency was at .06% at one sun and around 3% at 50 suns were demonstrated ...
