Receiving a grant by the EU Fast Track to Innovation program (FTI), SolarWin is a project aiming to scale-up and validate next-generation transparent Photovoltaic (PV) windows for commercial use and mass-production. Our R&D team, together with partners Sunplugged, Acciona, and IREC, is working on achieving this goal by 2021.


To revolutionize the Building Integrated PV (BIPV) and architecture sectors, by providing sustainable window solutions with value-added characteristics.

Product details

The concept is based on and designed as a luminescent solar concentrator (LSC). It incorporates an innovative luminescent coating that absorbs surplus light in the visible region and re-emits it in the near-infrared (NIR) region. The re-emitted light travels through the window towards the CIGS customized PV modules, which collect re-emitted light and generate green energy. A key element in this window concept is the use of a luminescent layer absorbing in the visible region and emitting in the NIR region.


From October 1st, 2019 to September 30th, 2021, the SolarWin project will receive a 3-million euros contribution for research activities. The coordination is done by IREC. Project: H2020-EIC-FTI-2018-2020-870004


Coming soon.
