ABSTRACT Mesoporous tungsten carbides displayed an excellent solar conversion efficiency (7.01%) as a counter electrode for dye sensitized solar cells under 100 mW cm(-2), AM 1.5G illumination, which corresponded to ca. 85% of the efficiency of the conventional platinum electrode.

    ABSTRACT: Ordered mesoporous titanium nitride-carbon (denoted as OM TiN-C) nanocomposite with high surface area (389 m2 g–1) and uniform hexagonal mesopores (ca. 5.5 nm) was facilely synthesized via the soft-template method. As a structure-directing agent, Pluronic F127 triblock copolymer formed an ordered structure with inorganic precursors, resol polymer, and prehydrolyzed TiCl4, followed by a successive heating at 700 °C under nitrogen and ammonia flow. In this study, the amorphous carbon within the parent OM TiO2-C acted as a rigid support, preventing structural collapse during the conversion process of TiO2 nanocrystals to TiN nanocrystals. The OM TiN-C was then successfully applied as counter electrode material in dye-sensitized solar cells (DSCs). The organic electrolyte disulfide/thiolate (T2/T–) was introduced to study the electrocatalytic property of the OM TiN-C nanocomposite. Because of the existence of TiN nanocrystals and the defect sites of the amorphous carbon, the DSCs using OM TiN-C as a counter electrode showed 6.71% energy conversion efficiency (platinum counter electrode DSCs: 3.32%) in the organic electrolyte system (T2/T–). Furthermore, the OM TiN-C counter electrode based DSCs showed an energy conversion efficiency of 8.41%, whereas the DSCs using platinum as a counter electrode showed a conversion efficiency of only 8.0% in an iodide electrolyte system. The superior performance of OM TiN-C counter electrode resulted from the low charge transfer resistance, enhanced electrical conductivity, and abundance of active sites of the OM TiN-C nanocomposite. Moreover, OM TiN-C counter electrode showed better chemical stability in organic electrolyte compared with the platinum counter electrode.

    ABSTRACT: Vanadium nitride (VN) peas and cubes were synthesized by regulating the molar ratio of the starting materials (urea/VOCl3) via the urea–metal chloride route. The as-prepared VN compounds were subsequently introduced into dye-sensitized solar cells (DSCs) as counter electrode (CE) catalysts for the regeneration of novel organic thiolate/disulfide (T–/T2) and traditional iodide/triiodide (I–/I3–) redox couples. The cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and Tafel polarization curve results proved that the catalytic activity of the prepared VN was significantly affected by particle shape and particle size. The VN peas showed the highest catalytic activity, followed by the small VN cubes and large VN cubes. The I–/I3–-electrolyte-based DSCs yielded a high power conversion efficiency (PCE) of 7.29%. The Pt-free VN CE catalysts are more suitable for the new organic redox couples of T–/T2. The DSCs based on VN peas CE showed a PCE of 5.57%, an enhancement of 40.7% relative to the Pt-CE-based DSCs (3.96%).

    ABSTRACT: Development of Pt-free catalyst materials for the counter electrode (CE) in dye-sensitized solar cells (DSSCs) has been regarded as one of the crucial steps to improving energy conversion efficiency and cost effectiveness of DSSCs. In this work, low cost tungsten oxide (WO 3-x) counter electrodes, prepared by annealing tungsten metal sheets under an Ar and low O 2 atmosphere, exhibited high catalytic activity and energy conversion efficiency. The highest efficiency achieved here for DSSCs with WO 3-x counter electrodes, was 5.25%, obtained from a 500 C annealed tungsten sheet. TEM and XPS analysis suggested the formation of sub-stoichiometric tungsten oxide layer ($WO 2.6) with the presence of W 6+ , W 5+ and W 4+ oxidation states at the tungsten metal surface after the 500 C annealing. Only W 6+ and W 5+ oxidation states were detected after a 600 C annealing indicating the formation of a more stoichiometric tungsten oxide layer ($WO 2.8) and resulting in a drop in efficiency of the DSSC. We suggest that mixed valence tungsten states account for the excellent catalytic activity and good electrical conductivity as evidenced by the highest cyclic voltammetry response of 0.76 mA/cm 2 and the lowest impedance value of 44.33 V, respectively.
