用于新兴光伏器件中电荷传输层的低维半导体纳米杂化材料

Abstract Emerging photovoltaics, such as perovskite and organic solar cells, have demonstrated remarkable power conversion efficiencies (PCEs), yet their performance and stability heavily rely on efficient charge transport layers (CTLs). Low-dimensional semiconductor nanohybrids, including quantum dots (0D), nanowires/nanotubes (1D), and nanosheets (2D), have recently emerged as promising candidates for next-generation CTLs, due to their tunable optoelectronic properties, enhanced charge carrier mobility, and superior interfacial engineering capabilities. This review comprehensively summarizes the latest advancements in low-dimensional semiconductor nanohybrids for the CTLs, focusing on their structural design, charge transport mechanisms, and performance enhancement in emerging photovoltaic devices. We discuss key strategies for optimizing nanohybrid-based CTLs, such as band alignment engineering, defect passivation, and morphological control, while highlighting their roles in improving charge extraction, reducing recombination, and enhancing device stability. Furthermore, we address the remaining challenges in scalability, interfacial compatibility, and long-term operational durability. Finally, we provide perspectives on future research directions, including scalable and low-cost fabrication, machine learning-assisted material discovery, and multifunctional nanohybrid architectures for high-efficiency, stable photovoltaics. This review aims to offer valuable insights into the rational design of advanced CTLs for next-generation solar energy conversion technology.
