What's Happening?
Researchers at the University of Rochester have made significant advancements in solar thermoelectric generators (STEGs), increasing their efficiency by 15 times. Unlike traditional photovoltaics, STEGs utilize thermal energy alongside sunlight to generate electricity. The new technique involves spectral engineering and thermal management, focusing on the hot and cold sides of the device rather than the semiconductor materials. This approach uses black metal technology to enhance solar energy absorption and heat trapping, while improving heat dissipation on the cold side. The study, published in Light: Science and Applications, demonstrates the potential of STEGs to power LEDs and other devices more effectively.
