FAPbI3 perovskites have garnered considerable interest owing to their outstanding thermal stability, along with near‐theoretical bandgap and efficiency. However, their inherent phase instability presents a substantial challenge to the long‐term stability of devices. Herein, this issue through a dual‐strategy of self‐assembly 3D/0D quasi‐core–shell structure is tackled as an internal encapsulation...
The stability of aqueous Zn‐ion batteries (AZIBs) is detrimentally influenced by the formation of Zn dendrites and the occurrence of parasitic side reactions at the Zn metal anode (ZMA)‐electrolyte interface. The strategic manipulation of the preferential crystal orientation during Zn2+ plating serves as an essential approach to mitigate this issue. Here, Zn aspartate (Zn‐Asp), an electrolyte additive...
Flexible perovskite solar cells (F‐PSCs) have emerged as promising alternatives to conventional silicon solar cells for applications in portable and wearable electronics. However, the mechanical stability of inherently brittle perovskite, due to residual lattice stress and ductile fracture formation, poses significant challenges to the long‐term photovoltaic performance and device lifetime. In this...
The pinhole‐free and defect‐less perovskite film is crucial for achieving high efficiency and stable perovskite solar cells (PSCs), which can be prepared by widely used anti‐solvent crystallization strategies. However, the involvement of anti‐solvent requires precise control and inevitably brings toxicity in fabrication procedures, which limits its large‐scale industrial application. In this work,...
Power generation by converting energy from the ambient environment has been considered a promising strategy for developing decentralized electrification systems to complement the electricity supply for daily use. Wet gases, such as water evaporation or moisture in the atmosphere, can be utilized as a tremendous source of electricity by emerging power generation devices, that is, moisture‐enabled‐electric...
In virtue of the high electrochemical activity and inherent flexibility, polyaniline (PANI) is an ideal electrode material for flexible supercapacitors (SCs). However, in practical applications, the inevitable agglomeration of PANI leads to low capacitance, poor rate performance, and cycling stability. Here, antimonene (Sb) nanosheets with ultrathin thickness, excellent mechanical strength, and flexibility...
In article number 1907690, Sijie Lin and co‐workers investigate the environmental hazard potential of nano‐photocatalysts, TiO2 and g‐C3N4 using the model organism zebrafish. With light irradiation, nano‐photocatalysts produce detrimental reactive oxygen species that would only exert adverse effects upon close nano‐bio interactions. The toxicity outcome is greatly influenced by light energy, water...
Nano‐photocatalysts are known for their ability to degrade pollutants or perform water splitting catalyzed by light. Being the key functional ingredients of current and future products, the potential of nano‐photocatalysts releasing into the environment and causing unintended harm to living organisms warrants investigation. Risk assessment of these materials serves as an important step to allow safe...
