Metal-free dyes (MD1 to MD5) containing an anthracene/phenothiazine unit in the spacer have been synthesized. The conversion efficiency (7.13 %) of the dye-sensitized solar cell using MD3 as the sensitizer reached approximately 85 % of the N719-based standard cell (8.47 %). The cell efficiency (8.42 %) of MD3-based dye-sensitized solar cells (DSSCs) with addition of chenodeoxycholic acid is comparable with that of N719-based standard cell. The MD3 water-based DSSCs using a dual-TEMPO (2,2,6,6-tetramethylpiperidine-N-oxyl)/iodide electrolyte exhibited very promising cell performance of 4.96 % with an excellent Voc of 0.77 V.
已合成了在间隔基中含有蒽/吩噻嗪单元的无金属染料（MD1至MD5）。以MD3作为敏化剂的染料敏化太阳能电池的转换效率（7.13%）达到了基于N719的标准电池（8.47%）的约85%。添加鹅去氧胆酸的基于MD3的染料敏化太阳能电池（DSSC）的电池效率（8.42%）与基于N719的标准电池相当。使用双TEMPO（2,2,6,6-四甲基哌啶-N-氧基）/碘化物电解质的基于MD3的水基DSSC表现出非常有前景的电池性能，效率为4.96%，开路电压优异，为0.77 V。
