A low-temperature and low-energy plasma surface treatment of nanoporous titanium oxide (TiO2) electrode for dye-sensitized solar cells (DSCs) is proposed using pulsed dielectric barrier discharge (DBD) under room air condition. When the treatment time is 10 min with the discharge voltage at 21.5 kV, the short-circuit current and the energy conversion efficiency are increased by 10% by the DBD treatment. The DBD treatment has advantages over previously studied plasma treatments of the TiO2 electrode of DSCs using a plasma jet or a low-pressure O2 plasma: (i) it requires no gas flow and no vacuum equipment, (ii) it is low-temperature treatment causing no damage on glass and plastic substrates, and (iii) it requires only a very low energy consumption. The DBD treatment is simple and cost-effective, having a strong potential for promoting the development of high-performance DSCs.
