“…The order of R ct estimated for the Pt films is consistent with those reported in the literature. 39,40 Importantly, the CE made of the O-Pt film unveiled a promising R ct of 0.89 Ωcm 2 smaller than that of the conventional CE (T-Pt CE) (1.44 Ωcm 2 ), yielding a quick charge transfer capability and superior catalytic reduction activity toward I À /I 3 À at electrolyte/electrode interface. These results also indicate that the interfacial contacts occurring in the components of DSSCs are improved after the introduction of the O-Pt film on the FTO surface.…”

An opaque platinum (Pt) film is deposited via the chemical bath method on an FTO substrate and assigned as a counter electrode (CE) of dye-sensitized solar cells (DSSCs). Optical properties opaque Pt film indicates the enhanced reflectivity compared to a conventional transparent Pt CE deposited by a spin coating method. The electrochemical impedance spectroscopy manifests the opaque Pt CE has a smaller series and charge-transfer resistances than that of transparent Pt. Tafel and cyclic voltammetry results verify the superiority of opaque Pt CE considering excellent electrocatalytic activity toward redox couple. A mechanical stability test affirms the excellent adhesion properties of the opaque Pt CE on FTO substrates. As a consequence, DSSC having the opaque Pt CE delivers a high electrical power conversion efficiency of 5.06%, outperforming the cell with the transparent Pt CE (4.31%) under the same conditions. Prospectively, the design of a device with an opaque Pt CE can be extended to other optoelectronic applications, opening up the opportunities for a host of high-performance devices.

The use of carbon-based nanofibers in this area has been especially important for the optimization of new counter electrodes [44,45]. High efficiency of DSSC are strictly related to the proper design of photo-anodes, especially related to the different interfaces among all materials, that is, dye/semiconductor/electrode.…”

During the last decade, carbon-based nanofibers emerged as an important class of materials for the fabrication of electrodes for electrochemical energy conversion. Indeed carbon-based nanofibers combine high electrochemical stability and high porosity to high mechanical flexibility and low weight, resulting in a unique and versatile material for the design and fabrication of energy-related devices. This chapter aims to show and analyze new nanostructured materials, obtained by electrospinning technique, in order to design 3D arrangement of the electrodes and to improve the energy efficiency of energy production devices. Indeed, the design of new 3D nanostructured electrodes enhances the energy efficiency of these devices, optimizing the energy production, obtained by new renewable energy technologies. The chapter is focused on those devices able to generate power output through the electrochemical conversion of different fuels, like wastes, and environmental compounds, such as CO 2 .

“…The basic components of a DSSC are a photoanode, a sensitizer, an electrolyte, and a counter electrode. The design of DSSCs currently involves a set of serial-stacked components: glass substrate, transparent conducting layer, TiO2 nanoparticles, dye, electrolyte, and counter electrode, which are gasket sealed [7]. Under solar illumination, photoexcitation of the dye molecules results in injection of electrons from the ground state of the dye to its excited state.…”
