The certified devices were manufactured on the company’s German pilot line, building on its record 28.6%-efficient tandem cell and ongoing efforts to scale mass production.
South Korea-based PV manufacturer Qcells has announced that its perovskite-silicon tandem solar technology has received certification from TÜV Rheinland, confirming compliance with reliability and safety standards established by the International Electrotechnical Commission (IEC) and UL Standards & Engagement (UL).
“Solar today is the most affordable and fastest-to-deploy energy resource on the planet. Qcells is working hard to build on this strong foundation and make it work even better. Achieving these milestones means we are getting closer to delivering a solar product that more immediately addresses the issues we care about most – from cost to carbon,” Fabian Fertig, Head of Tandem R&D for Qcells Germany, told pv magazine.
Qcells said it is the first company to obtain certification demonstrating compliance with both IEC 61215 and UL 61215 requirements for perovskite-silicon tandem technology. “These certifications are required to demonstrate that a solar panel is reliable and bankable. This achievement means these products can withstand significant stress without exceeding the power degradation limits defined by the standards,” the company said in a statement.
