A new window treatment developed at MIT that functions as a solar concentrator promises to finally bring solar windows to the masses. Based on similar work done in the ’70s, the dye mixture pulls in light at a range of wavelengths and re-emits it to solar cells at the edges of the window at a different wavelength — a technique good for a 40x increase in each cell’s power output, or 10 times what current systems can provide. The team estimates that the panels could become widely commercial within three years.
Imagine a skyscraper covered in that – yeah!

Based on similar work done in the 70s???? I can’t believe how long it’s taking to get people moving.
