Inorganic cesium lead halide perovskites (CsPbIxBr3−x, 0≤x≤3) are promising alternatives with great thermal stability. Additionally, the choice of moisture‐resistive and dopant‐free carbon as the electrode material can simultaneously solve the problems of stability and cost. Therefore, carbon electrode‐based inorganic PSCs (C‐IPSCs) represent a promising candidate for commercialization, yet both the efficiencies and stability of related devices demand further progress. This article reviews the recent advancement of C‐IPSCs and then unravels the distinctive merits and limitations in this field. Subsequently, our perspective on various modification strategies is analyzed on a methodological level. Finally, this article outlooks the promising research contents and the remaining unresolved issues in this field. We believe that understanding and analyzing the related problems in this field are instructive to stimulate the future development of C‐IPSCs. [ABSTRACT FROM AUTHOR]

At present, the development of electromagnetic wave absorption (EWA) materials is of great significance with the rapid development of electronic products. Based on the adjustable mechanical and electromagnetic properties of epoxy (EP)-based composite materials, research in the field of EWA has been continuously expanded. This review summarized recent developments of EP-based composites for their applications in EWA and classified composite materials according to the coating order and mixing ratio. In addition, the mechanisms of EWA were also introduced, including dielectric loss and magnetic loss. Finally, current challenges and opportunities for the development of EP-based EWA materials were proposed and the future development trend was pointed out. [ABSTRACT FROM AUTHOR]
