Chemical Functionality Engineering of Anti-Solvent Additives for Photostable Perovskite Solar Cells.
Metal-halide perovskite solar cells (PSCs) achieve high power-conversion efficiencies but remain susceptible to photo-induced degradation caused by mobile ions and phase segregation. Here, we investigate positional isomers of pyridine-carboxylic acid, namely pyridine-2-carboxylic acid (2-PC) and pyridine-4-carboxylic a...
