In the May 30th Economist, in a “Technology Quarterly” section, an article on work on transparent solar cells, including proposals to use
a family of crystalline materials called perovskites, which could allow semi-transparent solar cells to be made relatively cheaply in large rolls.
Ah, the minerals called perovskites, which reminded me of the garden plant called perovskia, which I grew in my Ohio garden. Turns out there are two different (and apparent unrelated) Russian counts named Perovski here, who lived and flourished at almost the exactly same time.
