    In this study, the synthesis of micro-wheels composed of self-assembled tungsten oxide nanorods supported platinum (WO3/Pt) by atmospheric plasma reduction and its application in a counter electrode (CE) for highly efficient dye-sensitized solar cells were discussed. To characterize the developed materials, we conducted SEM, TEM, EDS-TEM, XRD. Due to a large surface-active area of developed material and its support for Pt nanoparticles in diameters of 2–3 nm, the WO3/Pt electrode indicated as a greater electrochemical catalyst for the redox reaction than Pt and WO3 CEs. Thus, the power conversion efficiency for a device with WO3/Pt electrode is improved to 8.10%, compared to 4.36% for...

    Water evaporation-induced electricity generation technology has become an extremely interesting issue recently for supplying both freshwater and electricity. This review concentrates on advances in the recent development of water evaporation-induced electricity generation systems for possible application in the Internet of Things, resistive switching memory, devices collecting big data. Additionally, its application in powering some small electronic devices, energy storage, electrochemical deposition and electrochemical cells are also specifically clarified in this work. We divided water evaporation-induced electricity generation systems into three classifications, including tandem de...
