Summary A photovoltaic solar cell (PVSC) is a type of power system that uses photovoltaic technology to convert the energy of solar light directly into electricity and is therefore capable of operating only when illuminated. Because the sun does not shine at all hours of the day in a given location, solar power is intermittent. Due to this intermittency, PVSCs are unable to provide electricity during the evening and night. For this reason, it is essential to hybridize the PVSCs with electrical energy storage (EES) devices such as capacitors, Li‐ion batteries, and supercapacitors (SC) in one single power unit. One of the most promising support systems for meeting the enormous and diverse power demand in contemporary civilization is sunlight‐powered energy conversion, which simultaneously achieves power conversion and energy storage. SCs can store huge amounts of energy and have a long service life. They also have a fast charge‐discharge time, excellent cyclic stability, and outstanding low‐temperature performance. They are one of the alternatives to traditional batteries for replacing them because of their qualities. Growing demand for green energy, miniaturization, and wearable mini‐electronic devices will result from the combination of PVSCs and SCs into a single hybrid device. This paper describes an integrated system with a NiO2 nanotubular supercapacitor serving as an energy storage device and a nanostructured PVSC operating as an energy conversion device based on CdTe/CdS heterojunctions. Here, a PVSC is disposed of on the light‐receiving front side of a single glass slide, both of which are covered with conductive indium‐tin‐oxide (ITO) thin film and an AAO template with pores filled with a photosensitive (CdS/CdTe) material. The SC part of the device is located on its rear side. The main operations for the fabrication of the proposed device are listed. It was shown that the design features of the device allow combining and simultaneous execution of some similar fabrication operations, which would have to be carried out in the case of separate manufacture of the constituent elements of the device. To date, experimental studies on the practical implementation of the PV part of the device have been carried out. The preparation technique and structural, optical, and morphological properties of glass/ITO/AAO/CdS structures were investigated through XRD, scanning electron microscopy, energy dispersive X‐ray spectroscopy, Raman, and UV‐Visible spectroscopy. The materials were demonstrated to be quite suitable as raw materials for the production of solar cells.

“…For instance, AAO is attractive as template or host material for the growth of ordered nanotube or nanowire arrays for electrochemical applications like energy storage and conversion . As a few examples, AAO templates have been used to fabricate a nanostructured CdS‐CdTe solar cell or a photoanode for water splitting based on Fe 2 TiO 5 nanotubes . In these cases the AAO support is removed after the deposition of the guest material leading to free‐standing nanoporous structures.…”

Fluorine‐Doped Tin Oxide/Alumina as Long‐Term Robust Conducting Support for Earth‐Abundant Water Oxidation Electrocatalysts

In this work we apply a novel and simple methodology to develop a composite that consists of anodic aluminum oxide (AAO) covered by a fluorine‐doped tin oxide (FTO) film. The composite presents suitable morphological and electrical properties to be used as support for water electrooxidation catalysts based on non‐noble metals. AAO substrates were decorated with FTO via spray pyrolysis, followed by deposition of catalyst nanoparticles consisting of a cobalt‐analogue of Prussian Blue that promotes the oxygen evolution reaction. The electrodes were characterized by X‐ray Diffraction, Environmental Scanning Electron Microscopy and resistivity measurements. A promising electrocatalytic activity of the optimized AAO/FTO/PB electrode was observed at neutral pH and ambient conditions. The obtained results open a feasible strategy in the search for competitive water oxidation electrodes based on the combination of earth‐abundant metal catalysts on FTO‐covered anodized alumina supports.

The mechanical properties and interfacial structures for aluminum matrix composites reinforced by nanometer-sized SiC-β particles has been studied using molecular dynamics (MD) simulation. The modified embedded atom methods, was implemented to describe the atomic interactions. The molecular model undergoes an annealing MD simulation from 300 K to 1000 K to reach its minimum energy point. Tensile tests were performed with periodic boundary conditions. The stress-strain relationship has been studied and elastic constants were predicted as well. The results were compared with those given by continuum-based finite element analysis (FEA) together with the experimental data available in the literatures. It showed that both the elastic modulus and yield stress were further strengthened due to the presence of the nano-particles. Also, it was found that the existing SiC nano-particles have an effect on the initial arrangement of Al atoms in such a manner: Al atoms were inclined to aggregate around the particle surface. Aluminum concentrations were also observed inside the SiC particles close to the surface. The depth of hybridization is uniform and planar.
