New Energy Technologies Inc. is developing the SolarWindow solar film coating technology, which enables see-thru glass windows to generate electricity by ‘spraying’ their glass surfaces with New Energy’s electricity-generating solar coatings. SolarWindow solar film-coating technology makes use of ultra-small organic solar cells, which allow for the fabrication of transparent solar arrays on a broad range of substrate materials such as glass, plastic, and even paper. Resulting flexible and transparent solar plastic and solar paper sheets are suitable for portable solar power generation equipment.

Features of New Energy’s Electricity-Generating Solar Coatings

Transparent Solar see-thru Glass Window

  • New Energy’s SolarWindow solar film-coating technology makes use of ultra-small organic solar cells, which allow for the fabrication of transparent solar arrays on a broad range of substrate materials such as glass, plastic, and even paper.
  • SolarWindow solar coatings make use of the world’s smallest functional solar cells, which measure less than ¼ the size of a grain of rice, and have been successfully demonstrated to produce electricity.
  • SolarWindow solar coatings are sprayed on to see-thru glass using a novel process.
  • SolarWindow solar coatings do not require expensive high-temperature or high-vacuum production methods, but rather, can be sprayed on to glass at room temperature. Conventional solar films are typically manufactured using expensive and slow manufacturing methods which rely on high-temperature and finicky ‘vacuum deposition’ processes for depositing solar materials onto substrates; the resultant products are simply too thick to allow for transparency, an important consideration in the development of a commercially viable solar-powered glass window.
  • SolarWindow solar coatings generate electricity from both natural and artificial light sources, outperforming today’s commercial solar and thin-film technologies by as much as 10-fold.
  • SolarWindow™ solar coatings measure less than 1/10th the thickness of ‘thin’ films (only 1/1000th the thickness of human hair).

SolarWindow transparent solar film-coating technology is made of natural polymers which can be dissolved into liquid for easy application that does not require expensive and complicated high-temperature or high-vacuum production techniques common to other solar coatings. SolarWindow technology is capable of generating electricity on see-thru glass windows is under development for potential application in the commercial buildings and homes.
