About This Topic
Photovoltaic (PV) systems hold a key position in renewable energy field. The successful implementation of PV systems relies on several factors. Potential estimation, correct sizing, power electronics, energy conversion, grid stability, dynamic interactions, power quality, power system stability, public policy, investment, and incentives are all different parts of the puzzle for a smooth PV systems operation.
Solar thermal plants (STP) produce electricity using the heat obtained when concentrated solar radiation is converted into thermal energy. The useful heat thus obtained is then converted into electricity by means of a thermodynamic cycle (e.g., Brayton, Rankine, or Stirling). Estimates for global solar thermal potential indicate that it could more than provide for total global electricity needs. There are three primary solar thermal technologies based on three ways of concentrating solar energy: solar parabolic trough plants, solar tower power plants, and solar dish power plants. The mirrors used in these plants are normally constructed from glass, although other techniques are being explored. Power plants of these types use solar heat to heat a thermodynamic fluid such as water in order to drive a thermodynamic engine; for water this will be a steam turbine. Solar thermal power plants can have heat storage systems that allow them to generate electricity beyond daylight hours.
The main difference between a photovoltaic plant and a solar thermal plants is that in the PV panels the solar radiation is converted directly into electricity.
This Special Issue solicits papers that relate to the CSP plants, photovoltaic plant, solar energy, energy conversion, grid stability, electricity, thermal solar storage, performance ratio, and thermodynamic circles.

Abstract Heat integration techniques such as pinch analysis can play a significant role in saving energy in the design of buildings. The application of pinch analysis in this sector encounters difficulties due to the highly time-dependent behavior of energy streams such as waste heat and solar thermal collectors [...] |
Hot Water Preparation along with Combined Solar Thermochemical Energy Storage System: Experimental Validation and Performance SimulationAbstract Hybrid solar thermal systems are regarded as a promising solution for delivering clean thermal energy for building sector, especially when combining them with different renewable energy sources. Solar energy production usually does not match the thermal energy demand, and the energy storage must be integrated. Thermochemical energy storage [...] |
Zinc Silicate Thin Film Composites Obtained by a Sputtering Based Approach: Structural, Dielectric and Photovoltaic PropertiesAbstract Zinc silicates thin films have been obtained by a solid state two steps reaction, consisting in the sputtering deposition of alternating layers of Silicon and Zinc oxide reagents, followed by their annealing carried out at temperatures ranging from 300° to 560 °C, in air or under vacuum.

Melting/Solidification Processes of PEG 1500 in Vertical and Horizontal Annular EnclosureAbstract In this paper, the primary aim is to look at the fundamental melting/solidification processes of polyethylene glycol 1500 (PEG 1500) for energy storage – insulation to prolong the cooling time of pipelines in unexpected shut-down conditions, prevent/minimize the wax deposition, and hydrate formation. Polyethylene glycol 1500 was selected [...] |

Abstract The effect of water ingress on the surface of the buffer layer of a Cu(In, Ga)Se2 (CIGS) solar cell was studied. Such degradation can occur either during the fabrication process, if it involves a chemical bath as is often the case for CdS, or while the modules are in the field and encapsulants degrade. To simulate the [...] |
