无皂乳液聚合法合成聚苯乙烯微球应用于准固态电解质染料敏化太阳能电池

摘要

制备了一种提高染料敏化太阳能电池短路电流和电池光电转化效率的准固态凝胶电解质，该电解质含有5%高聚物PVDF-HFP和2% TiO₂纳米颗粒。另外，通过乙醇相无皂乳液聚合法合成了大小均一的聚苯乙烯微球，并用于制备染料敏化太阳能电池的多孔光阳极。研究了准固态电解质和液态电解质应用于不同光阳极染料敏化太阳能电池的规律。结果表明，与液态电解质相反，准固态电解更适用于孔洞较多的光阳极，在相同测试条件下，电池的短路电流由12.80 mA·cm^-2提高到13.53 mA·cm^-2，效率比液态提高11.43%，达到6.63%。

Abstract：

A novel polymer gel electrolyte was used to improve the short-current density and the overall performance in dye-sensitized solar cells. The polymer gel electrolyte was prepared by mixing 5% PVDF-HFP (poly(vinylidene fluoride-co-hexafluoropropylene)) and 2% TiO₂ nanoparticles. The monodispersed PS microspheres were synthesized by surfactant-free emulsion polymerization. Different photoelectrodes were obtained by adding different content of PS microspheres as pore-forming materials in photoelectrodes. In conclusion, the gel electrolyte is more conducive to the TiO₂ electrodes with more pores, the short current density (J_sc) increased from 12.80 mA·cm^-2 to 13.53 mA·cm^-2. The overall efficiency of DSSC with gel electrolyte and 7.5% PS microspheres as pore-forming material was 6.63%, which was 11.43% higher than the liquid electrolyte under the same test condition.

Keywords： dye-sensitized solar cells (DSSCs)； PS microspheres； quasi-solid electrolyte； PVDF-HFP
