As the increasing demand for smart photoelectric devices such as smart photovoltaic glass and smart temperature sensors, halide perovskite thermochromic materials are gradually emerging. It is widely focused and studied to apply the perovskite material to smart color-changing semiconductor devices due to its characteristics of quick color response with the temperature and reversible cycle. In this paper, firstly, several common liquid-phase preparation methods for perovskite and perovskite-like single crystal materials are introduced. Secondly, thermochromic phenomena of three-dimensional halide perovskite single crystal material, low-dimensional perovskite-like single crystal material, and other single crystal material are mainly introduced, including different materials showing two different thermochromic mechanisms due to their different structures: structural phase transition represented by low-dimensional perovskite material and lattice expansion represented by double perovskite materials. Thirdly, the advantages and disadvantages of thermochromic properties of different single crystal materials, such as whether they are reversible, are compared, and their development potential in multi-functional applications is introduced. Finally, the current challenges and future development of perovskite thermochromic materials are prospected.
