| الوصف: | This work reveals that the direct conjugation of metal halide perovskite nanocrystals on rGO sheets can provide high performance and stable electrodes for Zn-air supercapacitors. In particular, we provide a simple, rapid and room temperature laser-triggered method to anchor CsPbBr3 nanocrystals on rGO sheets without affecting the initial morphology and crystal structure of the components. The flexible and high surface area of the rGO enables the conjugation of individual metal halide perovskite nanocrystals with the emergence of new synergetic functionalities from the combination of the two counterparts. These synergetic functionalities lead to the 178- and 152-times improvement of the specific capacity of the conjugated-based electrodes compared to the single rGO and perovskite electrodes respectively.
