Preparation of CoNi@CN composites based on metal-organic framework materials as high efficiency counter electrode materials for dye-sensitized solar cells

The electrochemical performance was significantly enhanced by CoNi@CN retains the large specific surface area, high porosity and abundant unsaturated sites of MOFs, which provide a large number of reactive active sites, and as-assembled dye-sensitized solar cells (DSSCs) delivered an impressive power conversion efficiency of 9.58% at 100 mW·cm−2 illumination (AM 1.5G).
