Abstract

Effect of oxygen (O₂) plasma treatment of mesoporous TiO₂ photoelectrodes on the performance of dye sensitized solar cells (DSSCs) is presented. DSSCs fabricated with O₂ plasma treated and untreated (Reference) photoelectrodes were characterized. It was observed that O₂ plasma treatment and the duration of treatment play an important role on dark and illuminated current-voltage (I-V) characteristics, where a 15 min plasma treated mesoporous TiO₂ resulted in lower dark saturation current density compared with the reference DSSC and improved short circuit current density (J_SC) and open circuit voltage (V_OC) of the DSSCs.
