Scientists from Michigan State University have produced a new type of solar concentrator which can be installed on pre-existing windows to convert them into renewable energy devices without compromising their appearance.

The “transparent luminescent solar concentrator” can be attached to clear surfaces of any size – from the screens of cell phones to full-scale building windows, to transform them into solar power generators without significantly compromising their transparency or colour. The solar harvesting system developed by Richard Lunt from MSU’s College of…
