Spray on Solar Film May Make Windows the New Solar Panels
The recent development of a spray on solar film by Norwegian solar power company, Ensol, may change the way people think of solar power. Instead of using solar panels to generate energy from the sun's rays, Ensol's patented spray on solar film can be applied to windows, and possibly also to exterior walls, to generate energy for a building.
The University of Leicester is helping Ensol develop its spray on solar film. Chris Binns, a professor of nanotechnology at the school, stated that windows coated with the spray on solar film would appear to have a slight tint, as the film would absorb some of the sun's rays, but that they would let most of the light through. The walls of a structure, however could be coated with a more absorbent film, as no light would need to pass through.
Ensol is hoping to refine its spray on solar film and achieve a cell efficiency of 20%. The spray on solar film is expected to be produced by the University of Leicester, and be available commercially by 2016.
