Improving TOPCon solar cell performance with rear treatment techniques

Improving TOPCon solar cell performance with rear treatment techniques

Researchers in China have investigated four strategies that minimize TOPCon solar cell surface recombination centers and improve light trapping performance. They identified alkali polishing with micro-texturing as the most suitable technique to improve TOPCon cell open-circuit voltage and fill factor and the overall device performance.A research team from China's Yangzhou University has investigated how four rear treatment techniques can improve…
