About this collection
Guest Edited by Dr Lakshminarayana Polavarapu (University of Vigo, Spain), Professor Maria Antonietta Loi (University of Groningen, Netherlands), Professor Haibo Zeng (Nanjing University, China) and Dr Joseph M. Luther (National Renewable Energy Laboratory, USA).
Over the past decade, metal halide perovskites, both in the form of thin films and colloidal nanocrystals (NCs), have emerged as a leading candidate for optoelectronic applications because of their exciting properties including defect tolerance, long charge carrier diffusion lengths, high photoluminescence quantum yield, and facile fabrication using relatively low-cost precursors. We have witnessed a steep increase in the efficiency of perovskite optoelectronic devices such as solar cells, LEDs, and photodetectors in a short development time. Despite tremendous success in achieving efficiencies as high as those of classical semiconductors such as silicon and metal chalcogenides, perovskite optoelectronics are still suffering from long-term chemical and operational stability along with toxicity and scalability to large-area devices. Currently, perovskites (bulk and nanocrystals) and corresponding devices are undergoing further optimization regarding the composition of A, B, and X sites, surface passivation, optimization of the device architectures, interfaces, and charge transport layers, and their encapsulation.
This special themed collection aims to provide a platform for the latest developments that address the challenges of halide perovskite optoelectronics and focuses on a variety of topics including composition engineering of bulk perovskite thin films for improving phase stability; synthesis of stable perovskite NCs by composition engineering, doping, and passivation; stable layered 2D (Ruddlesden–Popper (RP)) perovskite optoelectronics (solar cells LEDs, photodetectors, etc.); perovskite solar cells with improved chemical and long-term stability, and efficiency; defect passivation of perovskite solar cells and LEDs; lead-free perovskite optoelectronics; device encapsulation; large-area devices; charge carrier dynamics and transport properties of thin films made of bulk and colloidal NC perovskites.
