This tutorial review focuses on recent work addressing the properties and potential of semiconductor nanowires as building blocks for photovoltaic devices based on investigations at the single nanowire level. Two central nanowire motifs involving p-i-n dopant modulation in axial and coaxial geometries serve as platforms for fundamental studies. Research illustrating the synthesis of these structural motifs will be reviewed first, followed by an examination of recent studies of single axial and coaxial p-i-n silicon nanowire solar cells. Finally, challenges and opportunities for improving efficiency enabled by controlled synthesis of more complex nanowire structures will be discussed, as will their potential applications as power sources for emerging nanoelectronic devices.
本教程综述聚焦于近期的研究工作，这些工作基于单纳米线水平的研究，探讨了半导体纳米线作为光伏器件构建单元的特性和潜力。涉及轴向和同轴几何结构中p-i-n掺杂调制的两种核心纳米线结构作为基础研究的平台。首先将综述说明这些结构单元合成的研究，随后考察近期关于单根轴向和同轴p-i-n硅纳米线太阳能电池的研究。最后，将讨论通过可控合成更复杂的纳米线结构提高效率所面临的挑战和机遇，以及它们作为新兴纳米电子器件电源的潜在应用。
