Hierarchical ZnO/NiCo2O4/Nb2C: A Novel Counter Electrode for Platinum-Free Dye-Sensitized Solar Cells
The development of sustainable, cost-effective, and high-performance counter electrodes (CEs) remains a major challenge in dye-sensitized solar cell (DSSC) research. Although Pt remains the benchmark CE because of its excellent electrocatalytic activity and electrical conductivity, its scarcity and high cost motivate t...
