N2 - Lead-free halide perovskites are promising materials for solar energy applications. However, their efficiency is hindered by poor light absorption in the visible-near-infrared region. Herein, we introduce vanadium (V) with low-lying ground/excited-state energy levels to form two types of stable lead-free V-based perovskite (Cs2NaVCl6 and Cs3V2Cl9) colloidal nanocrystals (NCs) with strong light absorption covering the ultraviolet to near-infrared region. We find the absorption can be further enhanced by structural regulation, in which the zero-dimensional (0D) Cs3V2Cl9 NCs show stronger and red-shifted (up to 1400 nm) light absorption compared to the three-dimensional Cs2NaVCl6 NCs. In 0D Cs3V2Cl9 NCs, [V2Cl9]3- dimers play a vital role in governing strong visible-near-infrared light absorption. We demonstrated their application for photocatalytic CO2 reduction.
