USA-based New Energy has developed a process of spraying solar cells onto glass, resulting in the production of its emerging solar window product. This development comes after the firm announced it was able to eliminate the metal material from solar cells used in the manufacturing of its see-through Solar Window. New Energy believes that spraying solar cells could provide significant commercial production advantages over today's thin films. The company said that conventional thin films are typically manufactured using expensive & slow manufacturing methods that rely on high-temperature & delicate vacuum deposition processes for depositing solar materials on substrates. "The resultant products are simply too thick to allow for transparency, an important consideration in the development of a commercially viable solar-powered glass window," New Energy says.
