Halide perovskites for emerging applications beyond photovoltaics: Recent progress and future prospects

Abstract

Metal halide perovskite (MHP) semiconductors have been widely known for their high-efficiency records in photovoltaic applications. This achievement has been possible due to their excellent optical and unique electrical properties, which are ideal for photovoltaics. Fast-advancing research has gained profound insight into a wide range of MHP families. Their excellent optoelectronic properties have attracted much interest and inspired researchers to investigate MHP for various other devices beyond solar cells. In addition, simple synthesis methods, low production costs, and chemical tunability of perovskites, which allow for alterations in their composition, structure, and properties through variations in elements and stoichiometry within their crystal lattice, have resulted in remarkable versatility in the design of MHP materials for diverse applications. MHPs possess ideal intrinsic properties, making them an eligible candidate for various optoelectronic and energy conversion devices. This review discusses the development and progress of perovskite-based devices in emerging fields, including transistors, light-emitting diodes, detectors, lasers, memory devices, and energy storage. The performance of various devices based on the MHPs has also been discussed. Notably, the literature indicates that MHP-based devices, utilizing various architectures and dimensions of MHP, have demonstrated impressive results equivalent to current state-of-the-art device technologies based on conventional semiconductor materials. However, MHP-based devices need further improvements and validation before being commercialized for widespread use. We have also discussed the challenges and prospects of perovskite-based devices in emerging fields.
