“…For the PAE‐treated cell, I RESET and the power consumption are reduced to as low as ≈0.06 mA and ≈0.12 mW, and the corresponding energy consumption ( J = I RESET * V RESET *reset time) is estimated to be ≈4.90 pJ per bit in the pulse operation mode. The I RESET and power consumption obtained here are far lower than those of most reported organic–inorganic hybrid perovskite‐based memristors [ 5,6,8,26–33 ] (see Table 1). One exception is the study by Ren et al, [ 34 ] who programed a layered perovskite single‐crystal ((PEA) 2 PbBr 4 )‐based memristor with extremely low I RESET /power consumption (3 × 10 −9 mA/3 pW).…”

Organic-inorganic hybrid perovskite memristors with high resistiveswitching (RS) reliability and low power consumption are crucial for high-density storage and high-efficiency neuromorphic computing. However, the current overshoot in the electroforming process generally induces overgrowth of conductive filaments (CFs) and degrades the RS performance. Here, a simple photo-assisted electroforming (PAE) method to suppress the current overshoot, in which the visible light irradiation is introduced into the initial electroforming process, is proposed for the first time. As a result, a reliable memristor with reduced RS fluctuation and enhanced cycling endurance is obtained, and also, the low operating current of 0.06 mA and low powerconsumption of 0.12 mW are achieved, which are about one order of magnitude lower than those of most reported hybrid perovskite-based memristors. Further experimental evidence indicates that light irradiation plays dual roles: 1) the lightinduced lowering of iodide migration barrier leads to a significant reduction of overshoot current and forming voltage; 2) the enhanced local photoconductivity of the perovskite film shares the overshoot current through the CFs. Both factors limit the total quantity of vacancy defects generated in the electroforming process, thus preventing undesirable overgrowth of the CFs. The present PAE strategy has promise for developing high-performance memristors.

Hybrid perovskites have created enormous research interest as a low-cost material for high-performance photovoltaic devices, light-emitting diodes, photodetectors, memory devices and sensors. Perovskite materials in nanocrystal form that display intense luminescence due to the quantum confinement effect were found to be particularly suitable for most of these applications. However, the potential use of perovskite nanocrystals as a light-harvesting antenna for possible applications in artificial photosynthesis systems is not yet explored. In the present work, we study the light-harvesting antenna properties of luminescent methylammonium lead bromide (CH NH PbBr )-based perovskite nanocrystals using fluorescent dyes (rhodamine B, rhodamine 101, and nile red) as energy acceptors. Our studies revealed that CH NH PbBr nanocrystals are an excellent light-harvesting antenna, and efficient fluorescence resonance energy transfer occurs from the nanocrystals to fluorescent dyes. Further, the energy transfer efficiency is found to be highly dependent on the number of anchoring groups and binding ability of the dyes to the surface of the nanocrystals. These observations may have significant implications for perovskite-based light-harvesting devices and their possible use in artificial photosynthesis systems.

Ion Migration: A “Double‐Edged Sword” for Halide‐Perovskite‐Based Electronic Devices

Ion migration has been regarded as one of the most interesting and mysterious processes in halide-perovskite-based electronic devices. On the one hand, ion migration contributes to the hysteresis and poor stability problems of perovskite devices. On the other hand, the mobile ions can passivate the interfaces of perovskite devices, leading to improved carrier transportation and collection. This article gives a critical review on the ion migration in halide perovskite materials. It starts with a brief introduction of the origin and nature of the ion migration problem in perovskite materials. Next, the electric, photoelectric, and structural phenomena resulting from ion migration and their influence on the performance and stability of the perovskite devices are focused on. The recent literature work on the characterization of ion migration is reviewed and the characterization techniques are highlighted. Furthermore, different approaches that can suppress the ion migration process are also introduced. Finally, ion migration in the emerging all-inorganic halide perovskite materials is compared with that in hybrid halide perovskite materials, and the implications on device design and performance are discussed.
