    In this study, the synthesis of micro-wheels composed of self-assembled tungsten oxide nanorods supported platinum (WO3/Pt) by atmospheric plasma reduction and its application in a counter electrode (CE) for highly efficient dye-sensitized solar cells were discussed. To characterize the developed materials, we conducted SEM, TEM, EDS-TEM, XRD. Due to a large surface-active area of developed material and its support for Pt nanoparticles in diameters of 2–3 nm, the WO3/Pt electrode indicated as a greater electrochemical catalyst for the redox reaction than Pt and WO3 CEs. Thus, the power conversion efficiency for a device with WO3/Pt electrode is improved to 8.10%, compared to 4.36% for...
