Laser welding enables more efficient solar panel recycling
Solar panels present a sustainable energy solution, but their recyclability can be hindered by the use of thin plastic layers encasing the solar cells. Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) have conducted a proof-of-concept study showing that the use of femtosecond lasers to form glass-to-glass welds for solar modules […]
