Oxford PV and the Fraunhofer Institute for Solar Energy Systems ISE have combined two high-efficiency technologies in a single photovoltaic module. To achieve this, they used perovskite-silicon solar cells from Oxford PV and connected them using the Matrix Shingle technology developed by Fraunhofer ISE. Oxford PV is a pioneer in perovskite-silicon tandem technology and was the first company to bring this next-generation solar technology into industrial production. The new module design will be on display for the first time at The Smarter E / Intersolar trade fair, taking place from 23 to 25 June 2026 in Munich. A rooftop module variant is on display at Fraunhofer ISE’s stand in hall A1.440, and a bifacial module for large-scale ground-mounted installations is shown at Oxford PV’s stand in hall A4.540.
“We are delighted to be able to combine two high-tech approaches from Europe in this PV module,” says Prof Dr Stefan Glunz, Head of Photovoltaics at Fraunhofer ISE.
“To achieve this, we have cut the solar cells from Oxford PV into shingles, arranged them in a matrix structure, electrically connected them using conductive adhesive, and then encapsulated them.” The tandem modules are glass-glass modules with edge sealing to protect the moisture-sensitive solar cells.
