142408 - Design and Synthesis of 3d Hydrogenated Carbon for Low-Cost Perovskite Solar Cells 

Graphene is a fascinating two-dimensional material, but easy restacking and a zero band gap restrict its practical applications. To solve these issues, we designed a new chemical reaction between lithium hydride and CO, achieving a one-step catalyst-free synthesis of hierarchically three-dimensional (3D) hydrogenated graphene (HG). Furthermore, it was demonstrated that the perovskite solar cells (PSCs) with 3D HG as a counter electrode exhibited a high power conversion efficiency and stability. Moreover, this material exhibited great performance in other energy devices, such as supercapacitors, fuel cells, and batteries. This would provide a novel approach not only to synthesize free-standing 3D graphene for energy devices but also to mitigate environmental concerns.
