An Old Rock Could Lead to Next-Generation Solar Cells – Scientific American

After a 170-year delay, the discovery of a strange, metallic-looking rock found in the Ural Mountains in Russia in 1839 has ignited a global technology race for a cheaper, more efficient solar cell. It could seriously disrupt the world’s solar market, currently dominated by China.

The features of the rock led to the understanding that there was not a particular mineral involved, but a class of minerals that share a common crystalline structure of cubes and diamondlike shapes. The structure was named for Lev Perovski, a Russian mineral expert who first studied it. He died in 1856. Later, researchers found that mineral deposits containing perovskite structures were cheap and abundant throughout the world.
