Using powerful femtosecond laser pulses to etch metal surfaces with nanoscale structures, they enhanced the material''s energy absorption from sunlight, while also reducing heat dissipation at
New, high-efficiency STEGs were engineered with three strategies: black metal technology on the hot side, covering the black metal with a piece of plastic to make a mini
A Rochester team engineered a new type of solar thermoelectric generator that produces 15 times more power than earlier versions.
This “black metal” absorbs more than 80 percent of sunlight while losing far less heat as infrared radiation.
The metal is made from tungsten and is useful in increasing photovoltaic efficiency because of its ability to absorb light at solar wavelengths.
