| Summary: | 碩士 === 國立清華大學 === 工程與系統科學系 === 103 === In this study, the molybdenum disulfide/ nitrogen doped graphene oxide nanocomposite (MoS2/nGO) was synthesized with nitrogen doped reduced graphene oxide (nGO) by hydrothermal synthesis method and molybdenum disulfide (MoS2) by thermal reduce method. This hybrid nanocomposite coated on fluorine doped tin oxide (FTO) glass as a platinum-free counter electrode (CE). The characteristics of MoS2/nGO were investigated by high-resolution transmission electron microscopy (HRTEM) and Raman spectroscopy. The electrochemical property of MoS2/nGO was characterized by cyclic voltammetry (CV), electrochemical impedance spectra (EIS) and Tafel-polarization measurement. This MoS2/nGO CE exhibited well photovoltaic conversion efficiency (PCE = 5.95 %). Compared with the conventional Platinum, the MoS2/nGO CE was up to 93.4% of using conventional Pt CE (PCE = 6.43 %). As a result of the MoS2/nGO nanocomposite could provide an alternative selection to replace the noble platinum as CE for DSSCs.
