Corona Discharge Treatment of TiO₂ Electrode for Dye-Sensitized Solar Cells in Air

Abstract

A nanoporous titanium oxide (TiO₂) electrode of dye-sensitized solar cells (DSCs) is treated using pulsed corona discharge in room air condition. When the treatment time is 10 min with the discharge voltage of 30 kV, the short-circuit current and the energy conversion efficiency of the treated DSC are 10% higher than those of untreated DSC. This result indicates that the treatment of TiO₂ electrode using a pulsed corona discharge in room air condition can enhance the energy conversion efficiency of DSCs.
