In a significant finding, scientists have developed a new low-cost, efficient and environment-friendly solar cell that can be used without hazardous material lead.
Researchers have developed a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light.
A pioneering study by U.S. researchers has led to the discovery that the humble metal tin could form the world`s first material to conduct electricity with 100 percent efficiency in computer chips.
