Crosslux - Turn glass façades into solar power plants

Aimed at replacing traditional, passive glass panes in large building façades, Crosslux's semi-transparent photovoltaic glazing is designed as an integral part of a building's enveloppe; it generates electricity from solar radiation, that can be fed directly to the building, thus reducing its dependency on public power networks. Using the façade to support electricity generation allows to take advantage of much larger surfaces than when you limit yourself to the roof, as is the case when deploying standard solar panels. Crosslux's glazing offers quite a few benefits: (a) Energy generation capabilities on par with the best photovoltaic technologies; (b) Almost invisible, chromatically neutral, transparency patterns for unprecendented visual comfort; (c) Transparency patterns and ratios that can be modulated panel by panel, or even within a panel, to optimize the trade-off between energy generation, aesthetics and lighting. Crosslux addresses the full transparency range, from 0% (an opaque panel, maximum electricity production) to 100% (clear glass, no production); (d) Low carbon impact compared to an electrically equivalent solution involving traditional glazing and photovoltaic modules; (e) Reinforced protection against ultra-violet and infrared radiation for increased thermal performance of the building; (f) Lifetime greater than 30 years and easy recycling at end of life; (g) Low overcost compared to standard glazing, allowing a return on investment of only a few years.

How it benefits society

Crosslux's glazing is a clean, local source of renewable energy for buildings, particularly efficient where space is scarce and buildings are tall, typically in urban environment. Able to fulfill a significant part of the building's need for energy, our solution paves the way to true zero- or positive-energy buildings. Durable, easily recycled, with low carbon footprint and short energy pay-back time, strongly appealing to architects, Crosslux's product generates a strong pull from the market.

Who we are


Pierre-Yves Thoulon, Marc Ricci
Aix-en-Provence, South of France

With 30 years of experience each in the high tech industry (microelectronics, computer industry), Marc Ricci (President) & Pierre-Yves Thoulon (CEO) started Crosslux in 2011. The idea was to develop a photovoltaic technology allowing to take advantage of the façade areas of large towers in urban environments to ease up the task of making these buildings autonomous in energy. Holding a PhD in materials physics, Marc has a past in the manufacturing and sales environment, and deals with the financial and business development aspects. With an engineering degree from Ecole Centrale de Paris (the second most renowned engineering school in France), Pierre-Yves brings 30 years of high tech R&D to the table and handles the day-to-day operation (production and services) and product and process development. With 6 people from 2012 to 2016 (most of them R&D engineers), Crosslux recently hired 14 more to support its development.
