UNSW research finds optimal cutting technique reduces TOPCon solar cell losses by 50%

University of New South Wales and DAS Solar used simulations to identify that cutting back-contact TOPCon cells in the gap region rather than the emitter region reduces efficiency losses by approximately 50%, with a 0.3 mm gap width optimiz
