The Fraunhofer Institute for Solar Energy Systems (ISE) has inaugurated a new laboratory aimed at accelerating the commercialization of tandem perovskite-silicon photovoltaic technology, according to the institute.
The facility, named ‘Pero-Si-SCALE’, is designed to provide research and development infrastructure for companies within the German and broader European PV sector. Its stated purpose is to expedite the market introduction of industrial tandem PV products while mitigating technological and financial uncertainties.
Fraunhofer ISE explained that the lab will enable solar cell and module manufacturers to access industry-standard production methods. This will allow them to scale new tandem cell architectures to larger formats, conduct analysis, and integrate them into modules.
During the opening, Fraunhofer ISE emphasized the potential of combining silicon and perovskite technologies. The institute noted that placing a perovskite cell, which is only 500 nanometers thick, onto a standard silicon solar cell could raise the cell’s theoretical efficiency ceiling from 29.4 percent to 43.3 percent.
Stefan Glunz, who heads the photovoltaics division at Fraunhofer ISE, stated that photovoltaic research is far from complete. He added that tandem solar cells are instrumental in achieving higher efficiency, which translates to more solar energy generation per unit area and reduced material consumption.
The Pero-Si-SCALE lab builds upon earlier laboratory developments, transferring novel cell designs to industrial formats—up to a wafer size of 210 by 210 square millimeters—through scalable, high-throughput manufacturing techniques. Alongside production technologies for perovskite-silicon cells and modules, the lab also offers a comprehensive characterization and analysis platform.
Fraunhofer ISE described its approach as following a ‘hybrid route’, which integrates vacuum and wet chemical processes in the production of perovskite-silicon tandem cells. The institute reported that this technology has already yielded peak efficiencies exceeding 33 percent on a laboratory scale.
A key advantage of this method, according to Fraunhofer ISE, is that standard, textured silicon solar cells from the industry remain usable. This allows for direct compatibility with existing solar cell standards and results in a higher energy yield from the tandem modules.
The lab’s opening occurs during a challenging period for Europe’s PV manufacturing sector, which has been losing market ground to China despite revival efforts.
Andreas Bett, institute director of Fraunhofer ISE, stated that perovskite-silicon tandem solar cells present an opportunity for European industrial PV manufacturing to re-enter or enter the market.
Fraunhofer has previously achieved notable progress in this field. In 2024, the institute disclosed details of a full-sized tandem module developed with perovskite specialist Oxford PV, which achieved a record efficiency of 25 percent.
