Book excerpt: Organic-inorganic halide perovskites (OIHPs) have emerged as excellent solution processable semiconductors for a new generation of potentially printable and efficient optoelectronic devices in recent years, including photodetection, energy harvesting, and light-emitting devices. The rise to prominence for this class of materials is fueled by their superior properties, such as tunable bandgap, high carrier mobility, outstanding optoelectronic merits, and low-cost solution processability. Given all exciting properties, solution-processed perovskite thin film also shows very challenging characteristics including difficult morphology control and substantial defects at film surface and grain boundaries (GBs). In this dissertation, integrated morphological and interfacial approaches have been utilized to overcome the above-mentioned challenges and further enhance performance of OIHP optoelectronic devices. Chapter 1 briefly overviews basics of perovskite material, current status of various perovskite optoelectronic devices, and remaining challenges for obtaining high quality solution processed perovskite thin film. Chapter 2 introduces common experimental details involved in this work including material preparation, material property characterization, device fabrication and performance test. Chapter 3 demonstrates a fast (
