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
Abstract: Femtosecond laser processing enables the fabrication of high-absorption, low-emissivity solar absorbers and highly efficient microstructured heat sinks for heat dissipation in solar
It is anticipated that further optimization and integration of such laser-engineered thermoelectric generators will accelerate the transition to a low-carbon economy and empower
To address these issues, we develop a spectral engineering and thermal management strategy that significantly increases STEG power generation by 15 times with only a 25% increase in
University of Rochester researcher Chunlei Guo has developed a solar thermoelectric generator (STEG) etched with femtosecond laser pulses that dramatically improves solar energy
The breakthrough lies in a unique, laser-etched "black metal" developed by researchers over the past five years, which they now hope to use in solar thermoelectric generators (STEGs).
Discover how black metal and lasers enhance solar thermoelectric generators, improving efficiency and potential applications in clean energy.
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 greenhouse, and laser
Rochester researcher Chunlei Guo tests a solar thermoelectric generator (STEG) etched with femtosecond laser pulses to boost solar energy absorption and efficiency.
