What You Talking About Willis?
The windows called high power density photovoltaic glass units are being made by Pythagoras Solar. They will retain views and daylighting for the floor, reduce heat and produce as much electricity as a traditional solar panel. The windows consist of monocrystalline silicon solar cells sandwiched between two layers of glass with an internal prism that directs the sunlight onto the solar cells, while letting diffuse light through. The result is a cooler, natural lighting environment inside the skyscraper and a more efficient solar panel.
