Abstract

An innovative two-step method perfectly prepared TCLs with different thicknesses, and then the TNA films based on TCLs were successfully prepared. The effects of different thicknesses of TCLs on the morphology and photoelectrochemical performance of TNA films were investigated. The results indicated that TCLs with appropriate thickness could effectively improve the morphology and photoelectrochemical performance of TNA films. Compared with the TNA films based on TCL, TCL and TCL, the TNA film based on TCL exhibited more ideal and comprehensive photoelectrochemical performance. Moreover, dye-sensitized solar cells (DSSCs) based on this TNA film achieved the highest (10.2054 mA cm), (0.5737 V), PCE (3.3%) and (3.31 mW cm).

摘要

一种创新的两步法完美制备了不同厚度的透明导电层（TCLs），然后成功制备了基于透明导电层的纳米结构阳极（TNA）薄膜。研究了不同厚度的透明导电层对纳米结构阳极薄膜的形貌和光电化学性能的影响。结果表明，具有适当厚度的透明导电层可以有效地改善纳米结构阳极薄膜的形貌和光电化学性能。与基于透明导电层、透明导电层和透明导电层的纳米结构阳极薄膜相比，基于透明导电层的纳米结构阳极薄膜表现出更理想和更全面的光电化学性能。此外，基于这种纳米结构阳极薄膜的染料敏化太阳能电池（DSSCs）实现了最高的光电流密度（10.2054 mA cm）、开路电压（0.5737 V）、光电转换效率（PCE，3.3%）和功率密度（3.31 mW cm）。
