Self-Tinting Windows Powered by Light

Jul-03-17 Self-tinting smart windows could one day harvest UV light from the sun as they also block the light.

Developed by a team from Princeton University, the key to the energy-generating smart windows are the transparent solar cells made of contorted hexabenzocoronene (cHBC) derivatives. The cHBC semiconductors were altered to absorb near-UV light, which is then used to power the electrochromic material that controls the glass’s tint.

The team hopes to develop the technology into a smart film that could be applied to existing windows and used to power small devices.
