RedOrbit: Using readily available equipment, researchers at from Northwestern University have developed a new type of solar cell based on tin instead of lead perovskite, according to a new report in Nature Photonics.
"This is a breakthrough in taking the lead out of a very promising type of solar cell, called a perovskite," said study author Mercouri G. Kanatzidis, an inorganic chemist at Northwestern. "Tin is a very viable material, and we have shown the material does work as an efficient solar cell."...
