Low-carbon, ultra-thin and highly-efficient silicon wafers for photovoltaics MoreLess

NexWafe GmbH is a pioneering company in the solar energy sector, specializing in the production of monocrystalline silicon wafers using their proprietary Kerfless Wafer Technology. This innovative approach allows NexWafe to produce EpiWafers, which serve as a direct replacement for traditional Cz (Czochralski) wafers used in solar cell production. The key advantage of NexWafe's technology is its ability to significantly reduce waste and energy consumption, making the production process more efficient and cost-effective.

The company primarily serves solar cell manufacturers who are looking for high-efficiency, low-cost wafers without the need to modify their existing production lines. NexWafe operates in the renewable energy market, which is experiencing rapid growth due to increasing global demand for sustainable energy solutions.

NexWafe's business model revolves around manufacturing and supplying EpiWafers to solar cell producers. The company generates revenue by selling these wafers, which are produced using a saw-free manufacturing process that saves up to 60% of silicon material. This not only reduces production costs but also lowers energy consumption, making the wafers more affordable and environmentally friendly.

The company has received significant investment and recognition, including doubling of investment from Wermuth Asset Management's GGF2 and winning the Environmental Technology Award (Umwelttechnikpreis). NexWafe is also expanding its production capabilities with a new 250 MW kerfless wafer factory in Bitterfeld, Germany.

NexWafe's leadership team includes experienced professionals like Dr. Stefan Reber (CEO and Founder), Dr. Frank Siebke (CFO and Founder), and Peter Pauli (Chairman of the Board), who bring a wealth of knowledge and expertise to the company.

In summary, NexWafe is at the forefront of solar wafer technology, offering a cost-effective, efficient, and environmentally friendly alternative to traditional wafer production methods.
