An international research team has observed a significant increase in series resistance in LECO-treated TOPCon solar cells after temperature and bias treatment. The scientists said they now need to conduct further investigations into its impact on cell efficiency, reliability, and bankability. A group of researchers from the University of Oxford in the United Kingdom and China's metallization paste specialist Changzhou Fusion New Materials has identified a new failure mode in TOPCon solar modules manufactured via the so-called laser-enhanced contact optimization (LECO) process. The process is ...Den vollständigen Artikel lesen ...
