Improving solar panel recyclability with lasers

Solar panels are highly recyclable, but the use of thin plastic layers can hinder efficient recycling of valuable materials like silicon or silver. NREL has developed a method using femtosecond lasers for glass-to-glass welds in solar cells, reducing the need for plastic laminates. This innovation allows for easier recycling of glass, metal wires, and silicon in solar modules.
