Fraunhofer Solar Institute and EV Group jointly develop next-generation battery technology

The German Fraunhofer Institute for Solar Energy Systems has recently launched a collaborative research initiative with EV Group. Together, they have developed an innovative device and associated processes that enable the direct bonding of silicon wafers at room temperature. This breakthrough not only ensures excellent electrical conductivity and optical transparency but also represents a significant advancement in semiconductor manufacturing techniques.

This direct bonding technology, introduced by the German research team, marks a paradigm shift in material integration. By optimizing the process, it becomes possible to bond different materials directly, offering substantial benefits for the production of multi-junction solar cells. The potential applications are vast, and the technology is expected to open up new possibilities in the field of photovoltaics.

One of the most promising aspects of this innovation is its ability to seamlessly combine materials with lattice mismatches, such as gallium arsenide and silicon, gallium arsenide and indium phosphide, or even indium phosphide with gallium and other semiconductors. This capability could revolutionize the way complex structures are built, enabling more efficient and versatile solar cell designs.

The Fraunhofer Institute envisions this combined technology playing a crucial role in the development of next-generation three-dimensional battery structures. They believe it will significantly advance the performance of space-based solar systems and concentrator photovoltaic cells, which are critical for high-efficiency energy solutions in extreme environments. With continued research and refinement, this technology could become a cornerstone in the future of renewable energy systems.
