NexWafe GmbH, a Freiburg, Germany-based developer of technology for epitaxial fabrication of silicon wafers for photovoltaics, completed an €8m financing.
The round was led by Saudi Aramco Energy Ventures (SAEV) with participation from Green Gateway Fund 2 (GGF2) advised by Wermuth Asset Management GmbH (WAM) and existing investor Lynwood (Schweiz) AG.
The company intends to use the funds for the commissioning of its 5MW wafer production line in Freiburg, and for initial customer qualifications.
Led by Stefan Reber, CEO, NexWafe is advancing monocrystalline wafers that are fully compatible with standard cell and module fabrication processes. The target market includes solar cell producers.
The company, a spinoff from the Fraunhofer ISE, leverages its EpiWafer process to allow crystalline silicon layers to be deposited on seed wafers and subsequently detached to produce freestanding wafers, of any desired thickness without kerf loss.
