BUFFALO, N.Y. — Scientists have created thin films made from barium zirconium sulfide (BaZrS3) and confirmed that the materials have alluring electronic and optical properties predicted by theorists.

A group of researchers led by the Autonomous University of Querétaro in Mexico have proposed for the first time to fabricate thin-film solar cells relying on an absorber made of silver, barium, ...
