| 摘 要： | 采用强度调制光电流谱（IMPS）／强调制光电压谱（IMVS）技术，从电子传输和复合动力学的角度，研究了DSC的液态电解质中加入TBP后，电池光伏性能变化的电荷传输机理。研究结果表明：DSC电解质中加入TBP后，TiO2导带边负移，导致DSC的开路电压明显增大；同时光生电子注入动力降低，多孔薄膜中光生电子浓度减少，电子传...

| Abstract: | The electron transport and back-reaction in DSCs with and without TBP were investigated by intensity-modulated photocurrent spectroscopy（IMPS） and intensity-modulated photovoltage spectroscopy（IMVS）.The results indicate that the increase of the open-circuit voltage was attributed to the negative shift of the TiO2 conduction band potential by the surface adsorption of TBP.The negative shift of the TiO2 conduction band potential reduced the electron injection force and decreased the photoaccumulated charge concentration in the TiO2 film,which increased the electron transit time（Td） and decreased the short-circuit current.Overall,the addition of TBP into the electrolyte increased the efficiency of DSCs by 37%. |
