More Environmentally Friendly Solar Cells

More Environmentally Friendly Solar Cells

Researchers at Northwestern University have developed a new solar cell that uses tin instead of lead perovskite as a collector of solar energy. This cheap and environmentally-friendly solar cell can therefore be made without any high-tech equipment or hazardous materials. The new solar cell developed by the team uses a structure called a perovskite and utilizes tin instead of lead as the light-absorbing material. Lead perovskite is a solar cell material that can convert up to 15 per cent of sunlight to electricity, which is very close to the efficiency of the current solar cells. The team developing the new cells is certain that tin perovskite should be able to match or even improve on that result. These new cells are the brainchild of lead researcher Mercouri G. Kanatzidis, who first developed, synthesized and analyzed the material. Afterwards, him and nanoscientist Rober...
