Special Issue Information

Dear Colleagues,

Energy is currently an important global issue, given the likely decline in common resources (fossil fuels), along with the demand for high-performance energy systems. In this sense, renewable energy technologies have become the core elements of an accelerated energy transition to 2050, and their synergies are likewise important. The current drawbacks of the production systems of some renewable energies are their origin, which in some cases cannot be “on and off” when we want; therefore, there is a need to have the capacity to efficiently store the energy that cannot be used at the time of production.

The main of this Special Issue is to give an overview of innovation in PV and storage technology, covering all aspects of the value chain. Developing more efficient products by implementing advanced materials to constitute the next generation of energy and storage devices is also pursued. Topics of interest include:

  • New alternative absorbers, based on safe and raw materials (nitrides, oxides, etc.);
  • Transparent electrodes free of critical raw materials;
  • Selective contacts for energy and storage devices;
  • Implementation 2D materials to improve device performance;
  • Uses of functional graphenic materials in PV and energy storage technologies;
  • Advanced solar device concepts.

In this study, an amorphous nickel-phosphide (Ni-P) thin film was produced by electroplating, and its possible use as the anode material of a secondary lithium battery was explored. First, by changing the electroplating conditions, we created uniform and flat Ni-P thin films that contained 16–28 at% phosphorus. An evaluation of the manufactured thin film as anode material showed that a thin film with more phosphorus content had a higher specific discharge capacity. In particular, the initial gravimetric capacity of the electrode with the highest phosphorus content (28 at%) was comparable to that of graphite, but it had three times the initial volumetric capacity. The cycling stability improved with a higher phosphorus content. It was suggested that the adhesive strength between the substrate and thin film had a greater impact on the cycling stability than the physical damage caused by the volume changes during charging and discharging. To improve the specific capacity, we formed globular electrodeposits on the surface of the thin film. As a result, a discharge capacity comparable to the theoretical capacity of Ni-P was obtained, and the rate performance was additionally improved, without reduction in the life cycle. Full article

Chromium (Cr)-doped zinc oxide (ZnO) nanorods with wurtzite hexagonal structure were prepared through a thermal decomposition technique. The concentration effect of the Cr doping on the structural, morphological, and optical properties of the ZnO nanorods was established by correlating various measurements: transmission electron microscopy (TEM), photoluminescence (PL), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and several UV-visible studies. The obtained nanorods were investigated as photocatalysts for the photodegradation process of methyl orange (MO), under UV-vis light illumination. Different weights and time intervals were studied. A 99.8% photodegradation of MO was obtained after 100 min in the presence of 1 wt.% Cr III acetate hydroxide and zinc acetate dehydrate “ZnO-Cr1”. The kinetic rate constant of the reaction was found to be equal to 4.451 × 10−2 min−1 via a pseudo-first order rate model. Scavenger radicals demonstrated the domination of OH• radicals by those of O2•− superoxide species during the photodegradation. The interstitial oxygen site Oi is proposed to play a key role in the generation of holes in the valence band under visible irradiation. The ZnO-Cr1 photocatalyst displayed good cycling stability and reusability. Full article
