During the last decade, metal halide perovskites (MHPs) have emerged as a rising star in optoelectronics. Due to the intriguing optoelectronic properties of MHPs, cutting-edge optoelectronic technologies based on MHPs, such as perovskite solar cells (PSCs), light emitting diodes (LEDs), photodetectors (PDs), and lasers, have been leading the prevailing paradigm. Furthermore, MHPs have the advantages of simple and low-cost processing and tunable optical and electronic features, making them a rich and fertile ground for developing high-performance multifunctional optoelectronic devices and their future industrialization.
In a new paper, researchers provide a panoramic view of MHP optoelectronic characteristics and their revolutionary impact on next-generation optoelectronics. They begin by looking back at historical research milestones for metal halide perovskites (MHPs) and their optoelectronic devices. Following that, they discuss the origin of MHPs’ unique optoelectronic features and how to tune them by regulating their phase, dimensionality, composition, and geometry of metal halide perovskites (MHPs). They then demonstrate that, due to the simple property control of MHPs, various optoelectronic devices with desired performance can be designed. Finally, they emphasize the groundbreaking applications of MHPs-based devices on existing optoelectronic systems. This viewpoint aims to provide critical guidance for inspiring novel MHP research directions to promote the widespread use of metal halide perovskites (MHPs)in optoelectronics.
