| 제목 | Electrochemical catalytic activity of PtMo bimetallic nanoparticles and its application to the counter electrode of dye-sensitized solar cells |
| 초록 | This study presents the synthesis of PtMo nanoalloys on a SnO2:F (FTO) substrate using a dry plasma reduction. These alloys are used as counter electrodes (CEs) for dye-sensitized solar cells (DSCs). For this purpose, an experimental approach is designed for the co-reduction of Pt and Mo precursors with different volume ratios. HRSEM and XPS measurements are conducted in order to characterize the morphology and chemical composition of the PtMo alloys, respectively. The electrochemical catalytic activities are examined through CV, EIS and Tafel measurements. The effect of the CEs on the efficiency of the DSCs is confirmed through comparing their photovoltaic performances. As a result, the PtMo nanoalloys are successfully immobilized and well distributed on the FTO surface without agglomeration. The highest electrochemical catalytic activity is obtained for Pt0.7Mo0.3 CE. Thus, the highest efficiency of 8.51% is archived for the cell using the Pt0.7Mo0.3 CE. Note that the efficiency of the device using a Pt CE is only 7.86% Keywords: dry plasma reduction; PtMo alloy; counter electrode; dye-sensitized solar cell |
