An oxide mineral made up of calcium titanate that is expected to be commercialized in higher-efficiency solar cells in the 2020-2021 time frame. Named after Russian mineralogist Lev Perovski, who discovered it in the 1800s, perovskite may also be employed as quantum dots in future screen technologies due to its high color purity.

Automatic Solar Cell Window Shades
In 2018, using perovskite and carbon nanotube technologies, the National Renewable Energy Lab in Golden, Colorado developed clear window glass that emits electricity and darkens with sunshine. When the sun fades, the window becomes transparent again. The transparency range is 3% to 68%.
