用新合成的吲哚染料作为SnO2纳米晶薄膜光电化学太阳能电池的增感剂，在相同的实验条件下，能量转换效率为2.8%，而联吡啶钌染料（N-719）的能量转换效率为1.2%。结果表明，吲哚染料在SnO2表面形成的非猝灭聚集体和较好的表面钝化状态是该染料敏化电池效率较高的重要因素。
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.
