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 ...

The preparation of the Na₂S cathode involved several key steps. Purified Na₂S was synthesized from barium sulfide through controlled chemical reactions to ensure high purity. The Na₂S was ...

Barium zirconium sulfide is another chalcogenide perovskite being tested in relation to the development of more efficient solar cells. Researchers at Buffalo University, in New York state ...
