Next generation transparent solar windows based on customised integrated photovoltaics

ended

The main goal of Solar-Win is the industrial scale-up, validation under real-world operation conditions (TRL8) and commercialisation of next generation transparent and non-intrusive photovoltaic (PV) windows. The project will result in a unique transparent and electricity-generating window that merges the functionality of a PV module and a window in one, allowing a strong increase in the surface available in the building for generation of PV electricity. Solar-Win will revolutionize the Building Integrated PV (BIPV) and the architectural sectors, by providing a PV window solution featuring a unique set of characteristics, namely: (1) transparent and visually non-intrusive windows (with controlled visible transparency from 40% to 75%) able to generate up to 30 W/m2 of green electricity; (2) full compatibility with existing window manufacturing technologies; (3) lifespan equivalent to standard windows (20 years); and (4) cost effectiveness (cost increase of just 30% with respect to a standard window). To achieve these goals, solar-Win involves two Technology-based SMEs (PHYSEE and SUNPLUGGED from the Smart Window and PV sectors, respectively) coordinated by a flagship RTD organisation with a strong experience and background in technology transfer and optimisation of advanced PV technologies (IREC) and a leader constrution company (ACCIONA) which is the main costumer segment. The Project concept relies on the solar window patented technology developed by PHYSEE at TRL6, and on the highly flexible PV technology of SUNPLUGGED, which will be further optimised and customised for Solar-Win application. Solar-Win will overcome a major barrier that presently limits a further deployment of BIPV solutions, which relates to its intrusive character. Moreover, Solar-Win will allow achieving a disruptive advance extending drastically the possibilities for integration of PV solutions to virtually any kind of buildings, just by installing and/or replacing building windows.
