Watch Video of Largest Ever SolarWindow™ Generating Electricity

Capable of generating current and voltage while maintaining the transparent nature of ordinary glass, the featured nine-square-foot SolarWindow™ was created using the Company's patented LiquidElectricity™ coatings.

Solar powered smart windows break 11% efficiency

John Fitzgerald Weaver for Electrek: The smart window lowers building temperatures by shifting from clear to opaque under strong sunlight. When the shift to opaque occurs, the solar prototype begins electricity production.
