Abstract
Metal halide perovskites as a new generation of semiconductor optoelectronic materials,have great potential for applications in solar cells,light-emitting diodes(LEDs),and photodetectors.Typical perovskite photovoltaic devices are mainly based on polycrystalline thin-films.However,the numerous grain boundaries and high defect density in polycrystalline thin films hinder the improvement of device performance.Perovskite thin single-crystalline materials,due to their superior optoelectrical properties such as lower defect density and longer carrier diffusion length compared to polycrystalline thin films,have attracted great attentions in solar cells,photodetectors,X-ray detectors,and lasers.This review systemati-cally introduces the preparation techniques,optimization strategies(component engineering,additive engineering,interface passivation)and device application progress of perovskite thin single-crystalline materials.It focuses on the growth methods and performance regulation of perovskite thin single-crystalline materials.Additionally,it discusses the development of per-ovskite thin single-crystalline materials as solar cells,photodetectors,X-ray detectors,and as light-emitting devices.Subsequently,it introduces the patterning methods of perovskite thin single-crystal,including inkjet printing and patterning template-induced arraying techniques,as well as the challenges,and looks forward to the future development directions of perovskite thin single-crystal devices.关键词
