Oxford PV and Fraunhofer ISE have introduced a new photovoltaic module prototype that integrates Oxford PV’s tandem perovskite-silicon cells with Fraunhofer’s matrix shingle interconnection technology, according to a joint announcement from the two organizations.
The prototype will be displayed at Intersolar Europe in Munich next week. The partners reported that two versions of the module achieved an efficiency of 25.6% across the entire module area.
Stefan Glunz, head of photovoltaics at Fraunhofer ISE, explained that in the design, Oxford PV’s tandem cells are cut into shingles, electrically connected using conductive adhesive, and encapsulated. The modules are constructed as glass-glass units with edge sealing to protect the moisture-sensitive cells. Glunz commented that the collaboration combines two high-tech European approaches in a single PV module.
Ed Crossland, chief technology officer at Oxford PV, noted that the two technologies are complementary. He said the tandem technology and the shingle interconnection work well together technologically. Because perovskite-silicon solar cells produce lower current densities, they can be cut into wider strips, which improves productivity. Crossland added that tandem solar cells generate higher voltages and efficiencies than conventional cells, while the current is lower due to its distribution across two sub-cells. This lower current density helps reduce resistive losses within the module. He also pointed out that the adhesive interconnection of the matrix shingle technology is a low-temperature process and requires no copper connectors, which can lower operating costs and reduce stresses in module construction.
The new design has been deployed in two prototype modules: a 491-watt rooftop version with an area of 1.92 square meters, and a 546-watt bifacial model covering 2.13 square meters. Both achieved the same 25.6% efficiency.
Tandem modules combining perovskite and silicon technologies are widely regarded as the next major step in solar technology evolution. Adding a perovskite layer to a silicon cell can significantly boost conversion efficiency beyond the theoretical limits of silicon-only cells. Oxford PV has been a leading developer of tandem technology and is advancing it toward commercial deployment through its pilot production facility in Brandenburg an der Havel, Germany.
Fraunhofer’s matrix shingle technology bonds solar cell strips together with electrically conductive adhesives in an overlapping, staggered pattern similar to roofing shingles. This allows complete coverage of the module surface and high tolerance to partial shading. The matrix arrangement enables current to flow around shaded areas, potentially generating up to twice the power compared to conventionally connected PV modules, depending on shading levels, according to Fraunhofer.
The new PV modules were developed as part of the HoTSun research project, funded by Germany’s Federal Ministry for Economic Affairs and Energy. Both prototypes will be on display in Munich next week.
