New Energy Technologies, a solar energy startup here in the US, has developed a technique to manufacture “spray-on” photovoltaic windows. The technique should ramp up production speed and bring down costs. First of all, what’s meant by a spray-on window? New Energy Technologies gives a good run-down of the product, which they call SolarWindow, on their site. The tech uses an organic solar array made up of extremely small solar cells–they measure about a quarter of the size of a grain of rice.
