Dye-sensitized solar cells (DSSCs) are among the best devices in generating electrons from solar light energy due to their high efficiency, low-cost in processing and transparency in building integrated photovoltaics. There are several ways to improve their energy-conversion efficiency, such as increasing light harvesting and electron transport, of which plasmon and 3-dimensional nanostructures are greatly capable. We review recent advances in plasmonic effects which depend on optimizing sizes, shapes, alloy compositions and integration of metal nanoparticles. Different methods to integrate metal nanoparticles into 3-dimensional nanostructures are also discussed. This review presents a guideline for enhancing the energy-conversion efficiency of DSSCs by utilizing metal nanoparticles that are incorporated into 3-dimensional nanostructures.

染料敏化太阳能电池（DSSC）的效率高，处理成本低，并且在构建集成光伏电池时具有透明性，因此它们是从太阳能中产生电子的最佳设备之一。有几种方法可以提高它们的能量转换效率，例如增加光收集和电子传输，其中等离激元和3维纳米结构具有很强的能力。我们回顾了等离激元效应的最新进展，这些进展取决于优化尺寸，形状，合金成分和金属纳米粒子的整合。还讨论了将金属纳米颗粒整合到3维纳米结构中的不同方法。这项审查提出了一个准则，以利用结合到3维纳米结构中的金属纳米颗粒来提高DSSC的能量转换效率。
