Tin-Oxide Perovskites In article number 2200964, Non Thongprong, Thidarat Supasai, Nopporn Rujisamphan, and co-workers presented the pseudohalide salt of sodium tetrafluoroborate, whose anions have a higher electronegativity than other halide salts, with potential to passivate surface tin oxide while enhancing optoelectronic properties perovskite film. The current study presents facile effective method for moderate thermal stability performance solar cell devices.
