使用Al2O3和N3染料制备了一种交替组装的结构,该结构能够提高染料敏化太阳能电池(DSCs)的开路电压(Voc),短路电流(Jsc)和转换效率(η).为了研究(染料/Al2O3)交替组装结构的作用机理,使用电化学阻抗谱技术分析了电池的界面电阻,分析结果表明,随着交替组装结构中(染料/Al2O3)单元的增加,光阳极,染料,电解质界面的电阻降低,电池性能随之提高.基于电化学阻抗谱分析结果,建立了一系列的等效电路模型,从理论上解释了(染料/Al2O3)交替组装结构的作用机理.

N3 dye and Al2O3 were used to form an alternating assembly structure.The current density-voltage(J-V)characterization showed that this structure improved the performance of dye-sensitized solar celts(DSCs).Electrochemical impedance spectroscopy(EIS)was used to study the internal resistance of this alternating assembly structured DSCs.The results showed that the resistance at the sensitized TiO2/electrolyte interface decreased as the number of(dye/Al2O3)units increased,and the device's conversion efficiency improved significantly.Based on the EIS results,a series of equivalent circuit models were well established to investigate the dye/Al2O3 alternating assembly structure theoretically.
