New research sheds light on impact of sodium-induced degradation in heterojunction solar cells

University of New South Wales researchers investigated the impact of sodium-induced degradation in heterojunction solar cells under accelerated damp-heat testing. They considered three different types of sodium salts and identified the degradation mechanisms attributed to each contaminant. A research team from the University of New South Wales (UNSW) and Chinese-Canadian solar module maker Canadian Solar has investigated how heterojunction (HJT) solar cells are hit by sodium (Na) and moisture degradation under accelerated damp-heat testing and has found that most degradation modes predominantly ...
