分等级锐钛矿TiO2纳米线阵列的制备及其在CdSe量子点敏化太阳电池中的应用
Hierarchical Anatase TiO2 Nanowire Arrays on Ti-foil Substrate for CdSe Quantum-dot sensitized Solar Cells
量子点敏化太阳电池是一种新型的第三代高效太阳电池，具有极大的应用前景。本文利用水热法，首先在柔性的钛片基底上生长了光滑的TiO2纳米线阵列，并通过第二步水热反应制备出具有分支结构的分等级TiO2纳米线阵列，研究了其在CdSe量子点敏化太阳电池中的应用。实验结果表明，具有分支结构的分等级材料具有更高的表面积以负载敏化剂，同时保持了一维纳米阵列高效的电子传输特性，因此相比于光滑纳米线阵列，其光电转换效率提升近一倍，在标准光强下测试达到0.72 %。
s one type of the third generation solar cells, Quantum dot sensitized solar cells (QDSSCs) processes a bright future. In this paper, the hierarchical anatase TiO2 NWs array were synthesised through a two-step hydrothermal growth process on a flexible titanium foil substrate. The HNW photoelectrode offered a high surface area to load sensitizer while maintaining its well elctron tranfer ability. Therefore, the power conversion efficiency of CdSe Quantum-dot sensitized solar cells based on such photoelectrode showed a significant enhancement in compared to TiO2 nanowire with similar thickness,which achieved 0.72 %.
