摘要

ZnO is a promising candidate as low cost, porous semiconductor material for photoanodes in a dye sensitized solar cell. In this work, we investigate the performance of pure ZnO nanoparticles (ZNPs), Al~(2)O~(3)doped ZnO (Al@ZNPs) and ZnO/Nb~(2)O~(5)core–shell structure of photoanode material. These electrodes were sensitized with a pervoskite CH~(3)NH~(3)SnCl~(3)sensitizer. To study the effect of the Al~(2)O~(3), Nb~(2)O~(5)treatment with ZnO, the J–V and EIS parameters, the current density (Jsc),Open circuit voltage (Voc), fill factor (FF), electron life time (τ~(n)), electron mobility (µ) and charge collection efficiency (ƞ~(cc)) are calculated for the fabricated solar cells and the results are compared. It was found that the Al~(2)O~(3)doped ZnO with the sensitizer CH~(3)NH~(3)Sncl~(2)showed the highest efficiency of 9.41% under 100 mW/cm_(2)irradiation. The electron impedance spectroscopy revealed that the charge collection efficiency (ƞ~(cc)) of the solar cells is in the order of PSSC3 > PSSC4 > PSSC2 > PSSC1. In this work, the effect of blocking layer (Ta~(2)O~(5)) is also discussed. From the J–V and EIS analysis, the effect of blocking layer is appreciable and it is useful to increase the efficiency of the solar cell by the way of reducing the recombination of charge carriers process. Therefore, the increase of photocurrent is mainly due to the combined effect of the sensitizer competence and blocking layer.
