1835–45; < German Perowskit, named after Count Lev Alekseevich Perovskiĭ (1792–1856), Russian statesman; -ite ¹

Example Sentences

These simulations showed that introducing copper into the perovskite structure creates highly active sites near the gold particles.

From Science Daily

A team around the physicist Dr. Felix Lang from the University of Potsdam, Prof. Lei Meng and Prof. Yongfang Li from the Chinese Academy of Sciences, Beijing, now combine perovskite with organic absorbers to form a record-level tandem solar cell as reported in the scientific journal Nature.

From Science Daily

"Still, tandem solar cells were limited by the perovskite layer, which shows strong efficiency losses if adjusted to absorb only blue/green parts of the sun spectrum," he explains.

From Science Daily

"To tackle this, we utilized a novel passivation layer applied to the perovskite that reduces material defects and improves the performance of the whole cell."

From Science Daily

In their work, now published in Nature, Lang and colleagues combine two emerging solar cell technologies, namely perovskite and organic solar cells, that both are processed at low temperatures with a low carbon footprint.
