采用旋涂法、提拉法、水热法、涂覆法制备了TiO2薄膜,利用紫葡萄皮染料分子敏化了TiO2薄膜电极,制备出太阳电池.测试结果表明涂覆法制备的太阳电池的效率最好,初始短路电流密度、开路电压分别为2.840 mA/cm2和0.594mV,而稳定性最差.相同条件下,其电池短路电流密度、开路电压与初始短路电流密度、开路电压的偏差百分比分别为13.3％和10％.旋涂法、提拉法、水热法制备的电池初始短路电流密度分别为0.619,1.071和0.901 mA/cm2,初始开路电压分别为0.447,0.481和0.488 mV,稳定性基本一样,短路电流密度与初始短路电流密度的偏差百分比分别为9.3％,9.8％和9.3％,开路电压与初始开路电压的偏差百分比分别为8.2％,7.3％和6.9％.电池的不稳定性在初期很强,衰退很快,后期趋于缓和.“,”The TiO2 thin films were prepared by the spin coating method,Czochralski method,hydrothermal method and coating method.The TiO2 thin film electrodes were sensitized by dye molecules of the purple grape skin,and then the solar cells were prepared.The test results show that the efficiency of the solar cell prepared by the coating method is the best.The initial shortcircuit current density and open circuit voltage are 2.840 mA/cm2 and 0.594 mV respectively,and the stability is the worst.Under the same conditions,the deviation percentages of the short circuit current density and open circuit voltage of the cell from those under the initial condition are 13.3％ and 10％,respectively.For the cells prepared by the spin coating method,Czochralski method and hydrothermal method,the initial short-circuit current densities are 0.619,1.071 and 0.901 mA/cm2 respectively,the initial open circuit voltages are 0.447,0.481 and 0.488 mV re spectively,and the stabilities are basically the same.Moreover,the deviation percentages of the initial short-circuit current density from those under the initial condition are 9.3％,9.8％ and 9.3 ％ respectively,and the deviation percentages of the initial open circuit voltage from those under the initial condition are 8.2 ％,7.3 ％ and 6.9％ respectively.The instabilities of the cells are very strong at the early stage,decline very fast,and tend to relax at the later stage.
