Cyclic voltammetric deposition of discrete nickel phosphide clusters with mesoporous nanoparticles on fluorine-doped tin oxide glass as a counter electrode for dye-sensitized solar cells

Largely spaced Ni ₅ P ₄ nanoclusters are grown on FTO glass using cyclic voltammetric deposition which includes anodic dissolution of Ni-rich regions following the cathodic deposition, leading to a better activity than Pt in the I ⁻ /I ₃ ⁻ electrolyte.
