  • ARMOR GROUP has invested in Holosolis to become a 20% stakeholder in the company 
  • It aims to use its OPV experience to support its perovskite-silicon tandem production 
  • The French group will also back the commercial development of Holosolis in Europe 

The French solar PV manufacturing startup Holosolis has secured organic photovoltaics (OPV) company ARMOR GROUP as a stakeholder, giving a boost to the company’s tandem PV cell and module production plans in France’s Sarreguemines region.  

The 20% stake in Holosolis gives the Nantes-based ARMOR a seat on its advisory board. ARMOR said it will be able to contribute to the production of 10 million perovskite-silicon panels with this acquisition, using its experience in thin-film technology (see Merck Sells Printed Organic PV IPP Rights). 

It also plans to support Holosolis’ commercial development in France, Germany and the wider European markets.  

After concentrating our efforts for several years on OPV, which has proved to be a very promising but still immature technology, we have decided to focus our efforts on new-generation modules, because solving the climate crisis cannot wait and the need to act is urgent,” said ARMOR CEO Hubert de Boisredon. “We’ll be putting our 15 years of experience and R&D in the solar industry at Holosolis’ disposal to ensure the success of the project.” 

Holosolis was founded by EIT InnoEnergy, IDEC Group and TSE in May 2023 with plans to roll out a 5 GW fab, starting with TOPCon and venture into silicon and perovskite tandem in the future. The company secured solar cell metallization pastes producer Heraeus as a stakeholder in October 2023 (see Technology Company Invests In European PV Producer).
