Are solar thermoelectric generators a good source of energy?

(University of Rochester photo / J. Adam Fenster) Researchers engineered a solar thermoelectric generator 15 times more efficient than current state-of-the-art devices. In the quest for energy independence, researchers have studied solar thermoelectric generators (STEGs) as a promising source of solar electricity generation.

Can laser etched nanostructures power a solar thermoelectric generator?

ETCHED ENERGY: A close-up of laser-etched nanostructures on the surface of a solar thermoelectric generator. (University of Rochester photo / J. Adam Fenster) In the study, Guo and his research team provided a simple demonstration of how their STEGS can be used to power LEDs much more effectively than the current methods.

How do Steg solar panels work?

Unlike the photovoltaics currently used in most solar panels, STEGs can harness all kinds of thermal energy in addition to sunlight. The simple devices have hot and cold sides with semiconductor materials in between, and the difference in temperature between the sides generates electricity through a physical phenomenon known as the Seebeck effect.
