Self‐assembly of platinum nanoparticles were applied to fabrication of counter electrode for dye‐sensitized solar cells on conductive oxide‐coated glass substrate. The present Pt electrode exhibits high exchange current density of 220 mA/cm 2 , which is comparable to those prepared by electrodeposition. magnetron sputtering or thermal decomposition of platinum chloride. After analysis by transmission electron microscopy (TEM). atomic force microscopy (AFM) and X‐ray photoelectron spectroscopy (XPS), it was found that the catalyst was structurally characterized as nanosized platinum metal clusters and was continuously arranged on electrode surface. The present nanostructure electrode had high electrocatalytic activity for the reduction of iodine in organic solution.
