Size

The number of employees is not publicly specified, and as a private company, no revenue data for 2023 or later is disclosed. The company has raised approximately 95 million euros in funding, including a financing round of 30 million euros in May 2023 (source: eu-startups.com).

What They Do

NexWafe is an innovative company specializing in the production of advanced solar wafers. The company's core technology focuses exclusively on photovoltaics, manufacturing ultra-thin, high-efficiency monocrystalline n-type silicon wafers through a proprietary EpiWafer or EpiNex process. This process allows for the deposition of a crystalline silicon layer on a reusable substrate, eliminating the need for traditional methods of Czochralski crystal growth and wire sawing (source: netzerocompare.com). This technology reduces energy consumption by 40-70% and CO2 emissions by 40-70%, while cutting material waste from over 50% to under 10% (source: businesswire.com). NexWafe's products are designed for use in terrestrial solar projects, residential installations, and emerging applications such as tandem cells (source: nexwafe.com).

Projects & Track Record

NexWafe has an impressive track record in pilot projects, including a 5 MW pilot line in Freiburg that was launched in 2021, as well as the introduction of a commercial line in 2020. A notable project was a European solar project on 200 acres that achieved a 20% higher energy yield compared to conventional wafers (source: eu-startups.com). The company is currently planning to build its first commercial green wafer factory in Bitterfeld, Germany, supported by a financing round of 30 million euros (source: eu-startups.com).

Recent Developments

In the past two years, NexWafe has made significant progress, including the announcement of efficiency parity of 24.4% for HJT cells and 28.9% for tandem cells (source: businesswire.com). In May 2023, the company secured 30 million euros for the construction of its factory in Bitterfeld, while simultaneously completing a financing round of 39 million euros for a gigafactory in India (source: eu-startups.com). The company has also established a collaboration with Aramco Ventures for production in Saudi Arabia.

Working There

NexWafe offers a variety of roles in a growing team focused on expanding prototype production. The company culture emphasizes innovation, customer-oriented solutions, and the commercialization of research technologies (source: careers.nexwafe.com). The headquarters is located in Freiburg, with potential locations in Bitterfeld, the USA, India, or Saudi Arabia, while specific benefits or perks are not documented in the available sources.
