A spray-on material transforms an ordinary window into an energy generator.

EnSol, a solar power company from Norway, has developed a thin film that can transform ordinary windows into solar panels. The spray-on film contains metal nanoparticles and can be coated onto a glass window for it to absorb light and generate power, thus enabling a building to produce its own energy. The company has teamed up with the University of Leicester for developing the material and hopes to make it commercially available in the next few years.
