To improve the photoelectric conversion efficiency and reduce the cost of platinized electrodes of dye-sensitized solar cells (DSSCs), a systemic study was performed for preparing efficient platinized counter electrodes (CE) by the pyrolysis method, and an optimum process was obtained. Results indicate that the platinized CE using the optimizing pyrolysis achieves high photovoltaic efficiency close to that of the sputtering platinized electrodes, and this method may be used to economically prepare large-sized and high-performance platinum loaded CE.
