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 TOPCon device with a 21% efficiency. Researchers at École Polytechnique Fédérale de Lausanne (EPFL) and Center Suisse d'Electronique et de Microtechnique (CSEM) in Switzerland developed a novel single-step thermal annealing process for tunnel oxide passivating contact (TOPCon) solar cells. The new process is intended to simplify the annealing process, which is currently being implemented by the ...Den vollständigen Artikel lesen ...
