This is really clever. Not sure how effective it will be though. I'm sure it could make every window and screen a power source, but it probably won't.
The clever part is that it diverts the invisible light coming in through the window towards the edges, where it is converted to electricity by solar cells. As well as the visible light we see, the sun has infrared radiation, at a shorter wavelength, and ultra violet, at a longer wavelength. Other approaches to solar glass have usually reduced the amount of light getting through, by applying a solar film over the windows, containing semiconductors. Since the semiconductors are not covering the glass, and the diverted light is outside the visible spectrum, this won't make any difference to how the windows look.
