Novel counter electrodes based on NiP-plated glass and Ti plate substrate for dye-sensitized solar cells
Novel counter electrodes based on NiP-plated glass and Ti plate substrate were prepared by thermal decomposition of H2PtCl6. Their properties and application in dye-sensitized solar cells were investigated. Platinized Ti plate electrode (Pt/TP electrode) and platinized NiP-plated glass electrode (Pt/NiP electrode) exhibited the same electrochemical activity for triiodide reduction as platinized fluorine-dope tin oxide (FTO) conducting glass electrode (Pt/FTO electrode). However, Pt/NiP electrode and Pt/TP electrode have the advantage over the Pt/FTO electrode in increasing the light reflectance and reducing the sheet resistance, which resulted to improve the light harvest efficiency and the fill factor of the dye-sensitized solar cells effectively. Examination of the anodic dissolution indicated the good stability of the Pt/NiP electrode and Pt/TP electrode in the electrolyte containing iodide/triiodide.
