Scientists have discovered a material that might be science’s biggest overachiever. This material, which is a type of a mineral called perovskite, can turn sunlight, heat, and movement into electricity—all at the same time. What a show-off.

These were invented in 2009, and since then have been seen as the next big thing in renewable energy—they’re cheaper and more efficient than silicon solar cells, and that efficiency is increasing every year. As reports, “Perovskite solar cells have proven to be cheaper and more efficient than traditional silicon solar cells, and their efficiency levels have increased from 3.8 percent in 2009 to 22.1 percent, making them the fastest-advancing solar technology .
the researchers state that a type of perovskite called KBNNO converts solar, heat, and kinetic energy into electricity all at once. What’s more, it can do it all at room temperature, making it a practical energy solution. This is the first type of perovskite mineral that’s been able to do that. Impressive!
