SEE-THROUGH SOLAR GETS BETTER
A fully transparent solar cell that could make every window and screen a power source

“Unlike other ‘transparent’ solar cells that we’ve reported on in the past, this one really is transparent…[The research team is] confident that the transparent solar panels can be efficiently deployed in a wide range of settings, from ‘tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader.’…Solar cells, specifically the photovoltaic kind, make energy by absorbing photons (sunlight) and converting them into electrons (electricity). If a material is transparent, however, by definition it means that all of the light passes through…This is whyprevious transparent solar cells have actually only been partially transparent…To get around this limitation, the Michigan State researchers use…a transparent luminescent solar concentrator (TLSC)…[which transforms ultraviolet and infrared light…[and guides it] to the edge of plastic, where thin strips of conventional photovoltaic solar cell convert it into electricity…[It would be big if] we can produce large amounts of solar power from sheets of glass and plastic that look like normal sheets of glass and plastic…” click here for more
