利用静电纺丝技术, 在TiO2纳米粒子上电纺一层网状TiO2纳米纤维微孔膜作为光散射层, 并在TiO2纳米粒子中掺杂少量MgO以抑制电子和空穴的复合, 得到TiO2纳米纤维/纳米粒子复合光阳极用于染料敏化太阳能电池. 将这种光阳极分别与有机三苯胺染料SD2, SD3或钌染料N719及鹅脱氧胆酸(CDCA)共敏化时, 在AM 1.5 (100 mW/cm2)的模拟太阳光照射下, 染料敏化太阳能电池的光电转换效率达到6.35%～8.85%. 同时, 使用半固态电解质可以达到液态电解质90%的光电转换效率.

A novel composite photoanode for dye-sensitized solar cells (DSSCs) was fabricated by electrospinning the TiO2 nanofibers onto the TiO2 nanoparticles as a light scattering layer. The magnesium oxide (MgO) was doped in the TiO2 nanoparticles in order to suppress the recombination of electron and hole. When the composite photoanodes were sensitized by using the organic triphenylamine dyes (SD2, SD3) or a ruthenium dye (N719) with the co-adsorbent chenodeoxycholic acid (CDCA), the high power conversion efficiency (η) of 6.35%～8.85% was obtained under simulated AM 1.5 irradiation (100 mW/cm2). Meanwhile, the power conversion efficiency of the quasi-solid DSSCs reached about 90% that of liquid electrolyte DSSCs.

Key words: electrospun, microporous membrane, dye-sensitized solar cells, power conversion efficiency
