Special Issue Information

Dear Colleagues,

Nano-structured or thin-film solar cells are an exciting and promising approach for renewable (i.e., photovoltaics (PV)) energy generation and it offers variety of choices in terms of device design, modelling, fabrication, and analysis for the improvement of conversion efficiency. Nano-structured or thin-film technologies have a great potential to reduce the cost by eliminating wafer slicing and reducing the material consumption by a factor of more than ten. Existing progress in solar or PV systems is causing the demand for silicon wafers to outstrip the capacity to supply, creating a market entry opportunity for a number of competing thin-film technologies, as well as nano-structured solar cells. An absorber layer can be deposited at the required thickness, greatly reducing wastage provided source material utilisation is a very good approach. There are variety of substrates, such as insulators or metals, are used for the deposition of different layers using different deposition techniques. This versatility allows tailoring and engineering of the layers in order to improve the device performance and to improve the conversion efficiency of nano-structured solar or PV cells. For large-area devices required for realistic applications, thin-film device fabrication becomes complex and requires proper control over the entire process. Hence, proper understanding of thin-film deposition processes can assist in achieving high conversion efficiency for different nano-structured or PV cells. Research and development is a new, exotic and simple materials and devices, and innovative, but simple manufacturing processes need to be pursued in a focussed manner. Therefore, we welcome research and review papers (both theoretical and experimental) for the development of high conversion efficiency thin film solar or nano-structured solar or PV cells and related areas. This Special Issue will cover the following, but not limited to this list:

  • Nano-structured solar or PV cells

  • Muli-junction solar cells
  • Solar cells and PV systems
  • Nanotechnology for improvement of solar cell conversion efficiency
  • Semiconductor devices for the development of thin film solar cells
  • Renewable energy technologies for the development of high effocienvcy solar cells

We welcome papers on nano-structred solar cells, thin-film solar cells, semiconductor devices, PV systems, plasmoniuc solar cells, as well as cutting-edge examples or models from industrial practice that can be used to encourage sustainable development and performance of thin film solar cells for the improvement of conversion efficiency.

The solar photovoltaic (PV) system is emerging energetically in meeting the present energy demands. A rise in PV module temperature reduces the electrical efficiency, which fails to meet the expected energy demand. The main objective of this research was to study the nature of OM29, which is an organic phase change material (PCM) used for PV module cooling during the summer season. A heat transfer network was developed to minimize the experimental difficulties and represent the working model as an electrical resistance circuit. Most existing PV module temperature (TPV) reduction technology fails to achieve the effective heat transfer from the PV module to PCM because there is an intermediate layer between the PV module and PCM. In this proposed method, liquid PCM is filled directly on the back surface of the PV module to overcome the conduction barrier and PCM attains the thermal energy directly from the PV module. Further, the rear side of the PCM is enclosed by tin combined with aluminium to avoid any leakages during phase change. Experimental results show that the PV module temperature decreased by a maximum of 1.2 °C using OM29 until 08:30. However, after 09:00, the OM29 PCM was unable to lower the TPV because OM29 is not capable of maintaining the latent heat property for a longer time and total amount of the PCM experimented in this study was not sufficient to store the PV module generated thermal energy for an entire day. The inability of the presented PCM to lower the temperature of the PV panel was attributed to the lower melting point of OM29. PCM back sheet was incapable of dissipating the stored PCM’s thermal energy to the ambient, and this makes the experimented PCM unsuitable for the selected location during summer. Full article

The solar photovoltaic (PV) cell is a prominent energy harvesting device that reduces the strain in the conventional energy generation approach and endorses the prospectiveness of renewable energy. Thus, the exploration in this ever-green field is worth the effort. From the power conversion efficiency standpoint of view, PVs are consistently improving, and when analyzing the potential areas that can be advanced, more and more exciting challenges are encountered. One such crucial challenge is to increase the photon availability for PV conversion. This challenge is solved using two ways. First, by suppressing the reflection at the interface of the solar cell, and the other way is to enhance the optical pathlength inside the cell for adequate absorption of the photons. Our review addresses this challenge by emphasizing the various strategies that aid in trapping the light in the solar cells. These strategies include the usage of antireflection coatings (ARCs) and light-trapping structures. The primary focus of this study is to review the ARCs from a PV application perspective based on various materials, and it highlights the development of ARCs from more than the past three decades covering the structure, fabrication techniques, optical performance, features, and research potential of ARCs reported. More importantly, various ARCs researched with different classes of PV cells, and their impact on its efficiency is given a special attention. To enhance the optical pathlength, and thus the absorption in solar PV devices, an insight about the advanced light-trapping techniques that deals with the concept of plasmonics, spectral modification, and other prevailing innovative light-trapping structures approaching the Yablonovitch limit is discussed. An extensive collection of information is presented as tables under each core review section. Further, we take a step forward to brief the effects of ageing on ARCs and their influence on the device performance. Finally, we summarize the review of ARCs on the basis of structures, materials, optical performance, multifunctionality, stability, and cost-effectiveness along with a master table comparing the selected high-performance ARCs with perfect AR coatings. Also, from the discussed significant challenges faced by ARCs and future outlook; this work directs the researchers to identify the area of expertise where further research analysis is needed in near future.
