Researchers from the University of New South Wales (UNSW) and the University of Newcastle have found that "hidden contaminants" in TOPCon and HJT modules can cause power losses of up to 16%. The presence of these "hidden contaminants" in HJT and TOPCon glass-backed modules in damp heat induced degradation resulted in relative power losses of 10% to 16% after 1,000 hours of damp heat testing...
