Abstract: Perovskite solar cells (PSCs) have revolutionized photovoltaic research. The power conversion efficiency (PCE) of PSCs has now reached 25.7%, which is comparable to current state-of-the-art silicon-based cells. However, PSCs can only utilize light of 300-850 nm, resulting in wasted near-infrared (NIR) light, which occupies 45%-50% of entire solar spectrum, which is one of the main reasons limiting the development of efficiency. Related strategies to broaden NIR spectroscopy to break the theoretical limit efficiency of PSCs have recently attracted extensive attention. This review firstly outlines theoretical basis for improving the NIR spectroscopy, then systematically summarizes some key strategies and research progress to improve NIR spectroscopy of PSCs. We firstly provided a comprehensive overview of historical research experiments on narrow-gap perovskite absorber layers, rare earth up-conversion, tandem devices, and integrated perovskite/organic solar cells and given constructive suggestions for exceeding limit efficiency of PSCs. Finally, based on the development status of PSCs with NIR utilization, the current issues, solutions and future development directions of important aspects to improve NIR utilization of PSCs are systematically discussed. This review lays the foundation for the efficiency of PSCs beyond the Shockley-Queisser limit, and provides a certain development prospect.
