Using newly synthesized indoline dyes as sensitizers for photoelectrochemical solar cells based on SnO₂ nanocrystalline films, an energy conversion efficiency of 2.8% is achieved, compared with 1.2% for ruthenium bipyridyl dye (N-719) under the same experimental conditions. It is suggested that the formation of nonquenching aggregates and the better passivation of surface states on SnO₂ by indoline dyes are instrumental factors in giving a higher efficiency for the cell sensitized with this dye.
