Qcells has become the first company to receive certifications from UL Standards & Engagement (UL) and the International Electrotechnical Commission (IEC) for its silicon-perovskite tandem solar technology, according to a report from PV Tech.
German technical advisory firm TUV Rheinland verified that Qcells’ tandem technology complies with the IEC and UL 61215 standards. The company described this achievement as an important step toward bringing the technology to market. These standards evaluate the technical reliability and bankability of solar technologies, which have historically been the main obstacles to commercializing perovskite tandem technology.
The modules and cells that were tested came from Qcells’ pilot production line in Bitterfeld-Wolfen, Germany. The company stated that the products were manufactured using only mass-production processes for both cell and module fabrication. The site receives funding from the German Federal Ministry for Economic Affairs and Energy, the state of Saxony-Anhalt, and the European Union through the PEPPERONI project.
Fabian Fertig, head of tandem research and development at Qcells Germany, indicated that reaching these milestones means the company is moving closer to launching a product that is reliable, cost-effective, and performs better. Qcells added that the certifications demonstrate the company is approaching delivery of a product that meets the stability and standardization measures essential for determining commercial readiness.
Qcells’ tandem products use a two-terminal configuration, with a silicon bottom layer based on the company’s Q.ANTUM passivated emitter rear contact technology and a perovskite top layer. The modules employed tandem solar cells on full-area M10 substrates.
The solar industry has been working to commercialize perovskite tandem technology for years, with efforts accelerating recently. The material can absorb a broader portion of the light spectrum than silicon, which could enable significantly more efficient solar modules and higher power output. However, perovskite is a volatile material that degrades when exposed to light, air, and water, at a rate that has previously made it unsuitable for commercial solar use.
Several companies besides Qcells have made progress in commercializing tandem technology. Notably, British firm Oxford PV has advanced its heterojunction-based silicon-perovskite tandem technology, including partnerships with Fraunhofer ISE and licensing agreements with US-based First Solar and Chinese solar manufacturer Trina Solar.
