A Swiss research team has developed a novel single-step annealing process for tunnel oxide passivating contact (TOPCon) solar cells. Demonstrating the approach, the scientists built a proof-of-concept ...
PVD tools such as VON ARDENNE’s GIGANOVA platform offer new possibilities for the next generation of TOPCon production and beyond. Image: VON ARDENNE. The rise of tunnel oxide passivated contact ...
TOPCon solar cells are on their way to fully compete with PERC solar products, according to recent research from Germany’s Fraunhofer ISE. Efficiency gains for the TOPCon concept, however, are ...
