合成了以乙氧基取代的低聚对苯撑乙烯基为发色团的染料敏化太阳能电池（DSSC），详细阐述了染料结构、物理性质、电化学性质与DSSC性能之间的关系。染料S3 O在350-750 nm的光谱范围内显示出宽的IPCE光谱，染料S1 P在AM 1.5（100 mW/cm ~ 2）的照射下显示出高达4.23%的太阳能-电能转换效率（），而在类似的实验条件下，参比钌配合物（N719染料）的η值为5.90%。
Organic dyes with ethoxy-substituted oligo-phenylenevinylene as chromophores were synthesized for dye-sensitized solar cells (DSSCs), and the detailed relationships between the dye structures, photophysical properties, electrochemical properties, and performances of DSSCs were described. The dye S3O showed broad IPCE spectra in the spectral range of 350–750 nm, and the dye S1P showed solar energy-to-electricity conversion efficiency (() of up to 4.23% under AM 1.5 irradiation (100 mW/cm2) in comparison with the reference Ru-complex (N719 dye) with an η value of 5.90% under similar experimental conditions.
