New Solar Cell Minimizes Environmental Risks in Manufacturing Process

Scientists in England report the development of a new solar cell that minimizes environmental risks in the manufacturing process by using an element used in bath salts. Many of the solar panels you see on roof tops use special materials called semiconductors such as silicon to generate electricity. However, silicone is not especially good at absorbing sunlight, says Jon Major, physics professor at the University of Liverpool in England. “To absorb a useful amount of sunlight with...
