First attempt to build thin-film solar cells relying on absorber made of silver, barium, titanium, selenium

An international research team has demonstrated, for the first time, the technical feasibility of solar cells relying on absorbers made of silver, barium, titanium, and selenium (Ag2BaTiSe4). The simulations showed these devices may reach efficiencies of up to 29.8% and be based on different buffer layer materials.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, titanium, and selenium (Ag2BaTiSe4). The scientists explained that their approach consisted ...
