“…Perovskite, especially polycrystalline film‐based photodetectors, generally suffer from large electrical hysteresis and the most significant figures of merit for devices still need further improvement. Apart from the above mentioned approaches such as creating single crystal and low‐dimensional nanostructures, perovskite heterostructures taking advantage of the superior properties of heterojunctions are one of the most promising research directions because the optoelectronic characteristics of heterostructures are not only the combination of the individual contributions of both the components but also largely rely on the interfaces between the components . It has been demonstrated that the suppressed recombination rate of photogenerated carriers benefitted from the heterojunction at the interface will prolong the lifetime of carriers, which will contribute to higher responsivity and EQE.…”

“…To simply the fabrication procedure, the horizontal 1D oxide nanoarrays may be better candidates to integrate with perovskites, which enable the construction of a planar MSM‐structured photoconductors. In recent, our group designed and fabricated a MSM‐structured photoconductor based on hybrid ZnO nanofiber/perovskite (Figure b) . In such a device, ZnO/perovskite composites and the two adjacent ITO films acted as light‐absorbing materials and conductive electrodes, respectively.…”

Hybrid organic-inorganic perovskite materials garner enormous attention for a wide range of optoelectronic devices. Due to their attractive optical and electrical properties including high optical absorption coefficient, high carrier mobility, and long carrier diffusion length, perovskites have opened up a great opportunity for high performance photodetectors. This review aims to give a comprehensive summary of the significant results on perovskite-based photodetectors, focusing on the relationship among the perovskite structures, device configurations, and photodetecting performances. An introduction of recent progress in various perovskite structure-based photodetectors is provided. The emphasis is placed on the correlation between the perovskite structure and the device performance. Next, recent developments of bandgap-tunable perovskite and hybrid photodetectors built from perovskite heterostructures are highlighted. Then, effective approaches to enhance the stability of perovskite photodetector are presented, followed by the introduction of flexible and self-powered perovskite photodetectors. Finally, a summary of the previous results is given, and the major challenges that need to be addressed in the future are outlined. A comprehensive summary of the research status on perovskite photodetectors is hoped to push forward the development of this field.

“…In addition, one‐dimensional (1D) materials with unique nanostructure (nanofiber, nanobelt, and nanotube) are suitable for low‐concentration detection, which offer high sensitivity and fast response time for chemical sensors because of the large surface‐to‐volume ratios in 1D materials. Numerous synthetic methods have been developed to prepare 1D structured nanofibers of which electrospinning is a simple, fast, and cost‐effective approach to fabricate nanowire materials by electrostatic stretching …”

Electrospinning is a unique method to prepare 1‐dimentional nanofiber for large‐scale manufacturing. Here in, we demonstrated chemical sensors based on the semiconducting nanofibers with core‐shell structure by simple single‐nozzle electrospinning with the spontaneous phase separation. The core‐shell structure nanofiber has large active sites which make it highly sensitive to chemical analytes. The thickness of the sensing shell can be tuned by controlling the mass ratio of core and shell components. As a demonstration, the nanofiber‐based sensor exhibits high sensitivity to low‐concentration ammonia (ppb level), as well as stability and reversibility. This unique fast single‐nozzle electrospinning technique used to fabricate semiconducting nanofibers with core‐shell structure provides a facile and designable process for the integration of multifunctional organic semiconducting layer into the organic electronic system.

ZnO is a typical direct wide-bandgap semiconductor material, which has various morphologies and unique physical and chemical properties, and is widely used in the fields of energy, information technology, biomedicine, and others. The precise design and controllable fabrication of nanostructures have gradually become important avenues to further enhancing the performance of ZnO-based functional nanodevices. This paper introduces the continuous development of patterning technologies, provides a comprehensive review of the optical lithography and laser interference lithography techniques for the controllable fabrication of ZnO nanostructures, and elaborates on the potential applications of such patterned ZnO nanostructures in solar energy, water splitting, light emission devices, and nanogenerators. Patterned ZnO nanostructures with highly controllable morphology and structure possess discrete three-dimensional space structure, enlarged surface area, and improved light capture ability, which realize the efficient carrier regulation, achieve highly efficient energy conversion, and meet the diverse requirements of functional nanodevices. The patterning techniques proposed for the precise design of ZnO nanostructures not only have important guiding significance for the controllable fabrication of complex nanostructures of other materials, but also open up a new route for the further development of functional nanostructures.
