The impact of laser-assisted firing on TOPCon solar cell performance

UNSW and Jolywood studied the thermal stability of laser-assisted fired TOPCon solar cells during module fabrication and high-temperature stress, identifying hydrogen-related defect dynamics as the key factor behind degradation and recovery. They found lamination causes temporary efficiency losses that self-recover under light exposure, while optimized LAF can restore degraded contacts, providing practical guidance for reliable module manufacturing and testing.A group of researchers from the University of New South Wales (UNSW) in Australia and Chinese module manufacturer Jolywood has conducted ...
