摘　　要：以纯柠檬酸为碳源,分别使用十六胺(HAD)和4,7,10-三氧-1,13-十三烷二胺作为碳量子点表面钝化剂,采用一步合成法合成油溶性及水溶性2种碳量子点,以此为染料制备出染料敏化太阳能电池,研究了其光电性能和电化学阻抗谱.该电池采用光阳极-电解质-光阴极(对电极)结构.光阳极采用TiO2纳米颗粒多孔薄膜结构,电解质为常用I-/I3-电解质体系,光阴极为Pt薄膜电极.测试结果表明:在AM 1.5G标准太阳光照下,油溶性碳量子点敏化太阳能电池的短路光电流为0.515 mA/cm2,开路光电压为0.461 V,填充因子为63.17%,转化效率为0.15%;水溶性碳量子点敏化太阳能电池的短路光电流为0.598 mA/cm2,开路光电压为0.549 V,填充因子为65.59%,转化效率为0.22%.数值均优于已报道的文献.With pure citric acid as carbon source, HAD and 4, 7, 10-trioxa-1, 13-tridecanediamine as surface passiviation for carbon quantum dots, carbon quantum dots were synthesized by a one-step reaction in oil phase or aqueous phase and used as sensitizers for the fabrication dye-sensitized solar cells. TiO 2 nanoparticle porous electrode was used as photo-anode and Pt film electrode was used as photo-cathode. The electrolyte was I-/I3-. The photovoltaic performance of the prepared cell were revealt that under AM 1.5G illumination, the Isc, Voc, FF and power conversion efficiency values of oil-soluble carbon quantum dots are 0.515 mA/cm2, 0.461 V, 63.17% and 0.15%, respectively. While, the Isc, Voc and FF values of water-soluble carbon quantum dots are 0.598 mA/cm2, 0.549 V and 65.59%, respectively. Its power conversion efficiency is 0.22%, which are better than the reported results in other papers.
