Abstract
Enormous scientific interests focused on the improvement of the electrocatalytic activity of counter electrodes for their application in dye-sensitized solar cells (DSSCs). In this regards, we have elaborated a novel gold and platinum (AuPt) nanostructures via direct and indirect electrodeposition techniques; the first one is cyclic voltammetric, while the second one is a combination of amperometric and potentiostatic methods. The as-prepared AuPt nanomaterials, which were characterized by XRD, XPS, SEM, and CA, and electrochemical analysis such as cyclic voltammetry, electrochemical impedance spectroscopy, and Tafel polarization were employed as counter electrode in dye sensitized solar cells. The AuPt counter electrode prepared by cyclic voltammetric technique was the best electrocatalytic activity toward \({\text{I}}_{3}^{-}/{\text{I}}^{-}\) reduction, low charge transfer resistance of 9.2 Ω cm2, and good chemical and electrochemical stability in the electrolyte. The assembled cell with the Au/Pt electrode provided a maximum power density of 2.35 mW cm−2 with an efficiency of 2.35% under back illumination of 100 mW cm−2 and AM 1.5 G.
期刊介绍:
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
