The new "thin film" solar cell was designed by a Norwegian company and the raw material was a metal nanoparticle synthesized by researchers at the University of Leicester. These metal particles having a diameter of about 10 nanometers are embedded in a matrix of transparent compounds. Sticking them to the surface of glass doors, transparent roofs, and facades, it feels like it is lightly tinted.
According to Professor Crispins, a professor at the University of Leicester, this film is very thin and can turn a window into a generator. They can be affixed or they can be added directly to glass or other building materials during the manufacturing process. Even if it is laid on a large area, it will save much more than the investment of traditional solar energy devices, and it can even be added to the car roof to charge the battery. But if you rely on it to drive a car, the speed is about the same as a cart.
At present, small pieces of cells have been formed, and the next step is to systematically improve the technology and make the batteries reach 20% or higher efficiency.
