钙钛矿材料，特别是金属卤化物钙钛矿，表现出优异的性能，例如大的光学系数、高载流子迁移率、长载流子寿命、可调谐的折射率、大的X射线衰减系数和简单的加工技术。近几十年来，钙钛矿由于其在太阳能电池、发光二极管、光电探测器、X/γ射线探测器和激光中的多用途而在光电领域引起了极大的关注。然而，钙钛矿的广泛应用高度依赖于钙钛矿晶体和膜的质量。到目前为止，已经出现了几种钙钛矿生长技术和方法。本文对近年来实现钙钛矿生长的主要方法进行了分类和总结，包括溶液降温法（STL）、逆温结晶法（ITC）、反溶剂气相辅助结晶法（AVC）、旋涂法和化学气相沉积法（CVD）。通过分析总结，确定了STL法、ITC法和AVC法是生长高质量钙钛矿单晶的主要方法。旋涂法在制备钙钛矿薄膜方面具有显著的优势，而CVD法则有利于制备各种形貌的微/纳米钙钛矿材料。希望本文的综述能为科研人员制备钙钛矿相关材料提供全面的参考。
Perovskite materials, especially metal halide perovskites, exhibit excellent properties, such as large optical coefficients, high carrier mobilities, long carrier lifetimes, tunable resistivities, large X-ray attenuation coefficients, and simple processing techniques. In recent decades, perovskites have attracted significant attention in the photoelectric field due to their versatile utility in solar cells, light-emitting diodes, photodetectors, X/γ-ray detectors, and lasing. However, the wide applicability of perovskites highly depends on the quality of perovskite crystals and films. Thus far, several perovskite growth technologies and methods have emerged. Therefore, this review classified and summarized the main methods that have been employed to achieve perovskite growth in recent years, including the solution temperaturelowering (STL) method, inverse temperature crystallization (ITC), anti-solvent vapor-assisted crystallization (AVC), spin coating, and chemical vapor deposition (CVD). Through analysis and summary, it has been determined that the STL, ITC, and AVC methods are mainly used to grow high-quality perovskite single crystals. While the spin-coating method has a significant advantage in the preparation of perovskite films, the CVD method is propitious in the fabrication of a variety of morphologies of micro/nano perovskite materials. We hope that this review can be a comprehensive reference for scientific researchers to prepare perovskite-related materials.
