(Nickel) Substrate Nano-ZnO Dye-sensitized Solar Cell Preparation and Performance Research

With the rapid growth and development of the world and global economy, human material and living standards continue to improve and improve, people’s demand for renewable energy has become more and more, and many traditional energy sources, such as oil, natural gas, coal, etc., due to their limited storage capacity, serious environmental pollution during mining, and many other reasons, no longer fully meet the human demand for sustainable use of renewable energy in our era. Therefore, the development of a clean industrial energy is gradually becoming an important solution for contemporary Chinese enterprises to solve the problem of clean industrial energy utilization. Solar cells are an inexhaustible clean and green energy. It has great research and development and application value. It has attracted extensive research attention from social scientists. Among them, solar energy dye-sensitized battery solar plastic cells mainly have The dye process is simple, the cost of the preparation process is low, the conversion efficiency is high, and the large-scale production can be achieved throughout the year. Therefore, it has gradually become a hot spot in my country’s solar power battery technology research in recent years. This article aims to study the preparation and performance of (nickel) substrate nano-ZnO dye-sensitized solar cells. The optimal conditions for the synthesis of ZnO and the influence of different reaction conditions on the growth of ZnO were explored, and the growth mechanism of ZnO was speculated. The photoelectric synthesis catalytic conditions of the microspheres agglomerated between different sizes of ZnO are explored, and the direct influence of the small dye-sensitized micro-solar synthesis cells currently used in the synthesis on the synthesis of small dye-sensitized micro-solar cells is directly affected. Laboratory research results show that in order to use more reactive dyes for dye adsorption in order to improve the efficiency of the conversion using dye sensitizers and solar fuel cells, the dye film needs to pass through ZnO and be adsorbed by the dye at the same time. The morphological structure should not be too dense and the film should not be too thick; at the same time, the absorption of the dye film should be proportional to the overall coating thickness of the film. Therefore, the overall thickness of the film should be moderate when used in ZnO.

Polarized Raman spectroscopy of GaP nanowires under 5% elastic strain

Optical porperties of highly-strained gallium phosphide nanowires were investigated via polarized Raman spectroscopy. 5% elastic strain was created in individual nanowire lying on nickel substrate by the means of atomic force microscopy. Micro-Raman mapping along the nanowire cross section in parallel and perpendicular polarization was carried out. Strain-induced effects on transverse optical mode position and shape were analyzed. The pronounced splitting of the mode due to high level of strain was observed. It was found that in parallel polarization the mode shape is sensitive to the position of the pumping spot which can be attributed to enhanced light-nanowire coupling effects.

The influence of ultrasound on nucleation in electrodeposition of lead dioxide on a nickel substrate

The effect of ultrasound on the electrodeposition of lead dioxide from lead (II) nitrate on a nickel substrate was studied. It was shown that the highest electrochemical characteristics are observed for the prototypes of backup power sources based on the Pb/HClO4/PbO2 system, in which lead dioxide obtained by electrodeposition under the influence of an ultrasonic field on a nickel substrate was used.

All-Solid-State Asymmetric Supercapacitor Based on Ni–Co Layered Double Hydroxide and rGO Nanocomposite Deposited on Ni Foam

In recent years, supercapacitors have been extensively exploited as an alternative energy storage technology in various fields such as electronics, computer, and mechanical. In this context, we have reported the utilization of the Ni–Co LDH/rGO nanostructure, deposited on the 3D conductive nickel substrate, to fabricate electrode for supercapacitor application. The film formed on the nickel substrate demonstrated superior electric conductivity and higher surface area which resulted in rapid electron transfer and more active mass deposition. Vertical nanorods grown on the rGO sheet was found to maximize electrode performance with a maximum specific capacitance of 2987 Fg−1at a current density of 1 Ag−1. The asymmetric supercapacitor was fabricated with Ni–Co LDH/rGO as a positive electrode and rGO as a negative electrode, which has rendered an energy density of 39.9 Wh/kg with a power density of 1.48 kW/kg1. Based on the obtained results, the fabricated supercapacitor is envisioned to be exploited in various potential applications.
