The new, fast, and simple preparation method of counter electrodes for dye-sensitized solar cells has been presented and the optimization of the Pt precursor solution concentration has been described. The counter electrodes prepared with the use of the Pt precursor solutions in six different concentrations have been applied for the solar cells assembly and the parameters of the devices have been well characterized with photocurrent-photovoltage measurements and electrochemical impedance spectroscopy experiments. 90 mM has been found as an optimal concentration of Pt precursor solution.
