![]() Moreover, perovskites are considered to be a class of important low-dimensional layered materials, whose optical properties can be controlled by varying the number of layers, particularly at thicknesses lower than their exciton Bohr radius. Recently, low-dimensional PPMS with high quality have begun to receive increasing attention, primarily for their tunable optical and electronic properties due to quantum-size effects as well as their enhanced photoelectric performance compared with bulk materials. However, introduction of many defects and grain boundaries in three-dimensional (3D) bulk PPMS is unavoidable, which inevitably degrade its optoelectronic properties. The perovskite family now includes hundreds of substances, ranging from organic materials, inorganic materials to organic–inorganic materials, from polycrystalline film to bulk single crystal. Up to now, great progress has been made in the preparation and application of bulk PPMs. Furthermore, current challenges in the synthesis and application of PPMS using the CVD method are highlighted with suggested areas for future research. We mainly summarize the influence of different CVD technologies and important experimental parameters (temperature, pressure, growth environment, etc.) on the stabilization, structural design, and performance optimization of PPMS and devices. This paper provides an overview of the recent progress in the synthesis and application of various PPMs via the CVD method. Chemical vapor deposition (CVD) technology with high efficiency, controllability, and repeatability has been regarded as a cost-effective road for fabricating high quality perovskites. The key issue is: how can PPMs be prepared using an effective way which most of the readers care about. Meanwhile, PPMS and their constructed devices still present many challenges, such as stability, repeatability, and large area fabrication methods and so on. Perovskite photovoltaic materials (PPMs) have emerged as one of superstar object for applications in photovoltaics due to their excellent properties-such as band-gap tunability, high carrier mobility, high optical gain, astrong nonlinear response-as well as simplicity of their integration with other types of optical and electronic structures.
