PHYSEE wins Postcode Lottery Green Challenge

News - 20 September 2016

TU Delft start-up PHYSEE has won the Postcode Lottery Green Challenge. They were presented the award and the €500,000 prize at the annual Postcode Lottery event on 14 September, during which the five finalists pitched their business plans to the press, public, and a jury of experts.

A TU Delft spin-off, PHYSEE develops PowerWindows: transparent, electricity generating windows that convert light into electricity. Whereas commercial glass reflects approximately 30% of the light that hits it, the PowerWindow captures this energy and conducts it to the edges of the window, where solar strips mounted in the frames convert the light into electricity. During the final of the Postcode Lottery Green Challenge, PHYSEE invited the jury to visit their Mobile Lab, which is powered by electricity generated by two 1.8m x 1.8m PowerWindows.

Together with their first client, OVG Real Estate, PHYSEE has already made a successful start to the pilot project in an existing building. The first PowerWindow has been installed as part of an OVG Real Estate redevelopment project in Fellenoord (Eindhoven). This building is set to become Rabobank’s new regional headquarters.

Postcode Lottery Green Challenge 

The Postcode Lottery Green Challenge is the leading international competition for energy sector start-ups. ‘Being invited to participate in this competition is the largest compliment you can give a cleantech start-up’, noted Willem Kesteloo, CFO of PHYSEE. The inaugural edition of the Green Challenge was held in 2007, after Bill Clinton inspired the Dutch Postcode Lottery to seek out and invest in burgeoning enterprises behind dedicated, ingenious green inventions. The 10th edition of the competition was held this year at Amsterdam’s Westergasfabriek, under the watchful eye of Queen Maxima.

The prize money is intended to facilitate marketing the business plan. In concrete terms for PHYSEE, this means that the enterprise will be able to bring their PowerWindow to the market. The PHYSEE pilot with OVG Real Estate and Rabobank is set to run until the end of 2016. 30 m2 of PowerWindows will ultimately highlight the potential of the product.

Green City Solutions from Germany came second in this year’s Green Challenge, receiving a prize of €200,000 for their business plan. The other finalists were HomeBiogas (Israel), Ioniqa Technologies (The Netherlands) and (UK/Kenya).

PHYSEE is a TU Delft spin-off, resulting from research conducted by the Faculty of Applied Sciences into Luminescent Solar Concentrators. This research was headed by Erik van der Kolk.
