在此，我们回顾了我们在纳米结构光阳极的下一代光致发光，特别是染料敏化太阳能电池的最新进展。自下而上的自组装技术被开发用于制造大面积的3D纳米结构，其能够通过光学散射或光子晶体效应来增强电荷提取和光捕获，以改善光电流、光电压和填充因子。使用通用技术制造专用纳米结构可以实现特定的光电和物理特性，如传导，电荷提取，注入，复合和光捕获，但也有助于提高低成本材料的机械灵活性和长期稳定性。
Herein, we review our latest advancements in nanostructured photoanodes for next generation photovoltaics in general and dye-sensitized solar cells in particular. Bottom-up self-assembly techniques are developed to fabricate large-area 3D nanostructures that enable enhanced charge extraction and light harvesting through optical scattering or photonic crystal effects to improve photocurrent, photovoltage and fill factor. Using generalized techniques to fabricate specialized nanostructures enables specific optoelectronic and physical characteristics like conduction, charge extraction, injection, recombination and light harvesting but also helps improve mechanical flexibility and long-term stability in low cost materials.
