Abstract Lead‐free double perovskite Cs 2 AgBiBr 6 has attracted increasing research interest in addressing the toxicity and stability challenges confronted by lead halide perovskites. While most of studies on this material have been focusing photovoltaic performance potential applications, its long‐term degradation mechanism are well under‐explored.

Metal halide perovskites (MHPs) have excellent characteristics and present great potential in a broad range of applications such as solar cells, light‐emitting diodes, photodetectors. However, the light stability devices remains an unresolved issue has received research attention. Under illumination, MHPs exhibit various anomalous phenomena, photoluminescence (PL) enhancement, defect curing, PL blinking, phase segregation. These phenomena are commonly considered intimately correlated with...
Abstract Lead (Pb) halide perovskites have witnessed highly promising achievements for high-efficiency solar cells, light-emitting diodes (LEDs), and photo/radiation detectors due to their exceptional optoelectronic properties. However, compound stability Pb toxicity are still two main obstacles towards the commercialization of perovskite-based devices. Therefore, it is substantial interest search non-toxic candidates with comparable photophysical characteristics. Metal-halide double...

The stellar optoelectronic properties of metal halide perovskites provide enormous promise for next-generation optical devices with excellent conversion efficiencies and lower manufacturing costs. However, there is a long-standing ambiguity as to whether the perovskite surface/interface (e.g. structure, charge transfer or source off-target recombination) bulk are more determining factor in device performance. Here we fabricate an array CsPbI3 crystal hybrid glass composites by sintering...
Abstract Metal halide perovskite‐based devices can exhibit exceptional optoelectronic performance at relatively high defect densities, a phenomenon commonly referred to as tolerance, which is one of the most important features metal perovskites (MHPs). Defect tolerance previously thought be static property, determined solely by composition and manufacturing process. However, recent studies have shown that MHPs dynamic vary over time. For example, power conversion efficiency MHPs‐based solar...

Abstract A revolutionary concept of lattice battery solar cell (LBSC) is proposed to leap the conversion efficiency by inherently eliminating two major energy losses conventional cells, namely hot carriers and non‐absorption substantial near infrared (NIR) emission. In an LBSC, phonon emission will be saved into reservoir (LER) through electron–lattice coupling; NIR harvested NIR‐perovskite composition. The NIR‐generated are upconverted conduction band perovskites driven LER. theoretical...

Lead mixed-halide perovskites offer tunable bandgaps for optoelectronic applications, but illumination-induced phase segregation can quickly lead to changes in their crystal structure, bandgaps, and properties, especially the Br-I mixed system because CsPbI3 tends form a non-perovskite under ambient conditions. These behaviors impact performance practical applications. By embedding such glassy metal-organic framework, family of stable nanocomposites with emission is created. Combining...
