Researchers have developed a new solar cell with good efficiency that uses tin instead of lead perovskite as the harvester of light.
The low-cost, environmentally friendly solar cell can be made easily without fancy equipment or hazardous materials.
Mercouri G. Kanatzidis, an inorganic chemist with expertise in dealing with tin, said this is a breakthrough in taking the lead out of a very promising type of solar cell, called a perovskite. Kanatzidis said tin is a very viable material, and we have shown the material does work as an efficient solar cell.
