Over the last few decades, research works have focused on elucidating the optical properties of semiconductor materials. Despite remarkable progress in the measurement and calculation of the absorption coefficient for semiconductor materials, there is a lack of comprehensive review on the comparative study of absorption coefficient properties for different types of bulk semiconductor materials and their methods for calculating the absorption coefficient. Hence, this paper summarizes the fundamentals of the various methods used to determine the absorption coefficient properties of bulk growth semiconductor crystals, and discusses their advantages and disadvantages. Furthermore, this review provides comprehensive results from recent studies and findings on the absorption properties of near- to mid-infrared (wavelengths from 800 to 7300�nm) group III-V semiconductor materials. In addition, the absorption coefficient of the conventional group IV semiconductors (silicon and Ge) were included for performance comparison. Critical analysis was done for the reviewed materials concerning their material properties, such as band gap structure, crystal quality, and the structural design of the device. The related studies on the methods to determine the absorption coefficients of semiconductors and to improve the likelihood of absorption performance were well highlighted. This review also provides an in-depth discussion on the knowledge of absorption coefficient based on a wide range of semiconductor materials and their potential for sensors, photodetectors, solar and photovoltaic application in the near to mid infrared region. Lastly, the future prospects for research on absorption coefficients are discussed and the advancement in the determination of absorption coefficients for new ternary and quaternary materials is proposed using artificial intelligence such as neural networks and genetic algorithm. � 2022, The Minerals, Metals & Materials Society.

This paper examines the present status and challenges associated with Battery Energy Storage Systems (BESS) as a promising solution for accelerating energy transition, improving grid stability and reducing the greenhouse gas emissions. Serving as a key facilitator, BESS aids in integrating and balancing variable renewable energy sources to maintain a stable energy supply by storing excess energy and releasing it as needed. While global BESS deployment is on the rise, it falls short of aligning with storage capacity projections for a net-zero scenario, necessitating heightened efforts. In Malaysia, BESS is recognized as vital for system stability, prompting the government's plan to install 5 units of 100 MW BESS capacity by 2034. The establishment of grid codes and regulations is critical for the safe and reliable integration of BESS. Although specific guidelines for BESS grid integration are limited, certain sections from existing guidelines for Large Scale Solar (LSS) connections can be adapted. To enable widespread BESS implementation, challenges such as scalability, grid integration, and cost need to be addressed. Robust guidelines and regulations must be developed to successfully integrate BESS into the grid and pave the way for a sustainable energy future. The motivation behind this study is to assess the current state of research on BESS and its integration into power systems, identifying challenges and opportunities associated with this technology. Additionally, the paper aims to shed light on the role of grid codes in governing the connection and operation of BESS and other energy storage systems within the grid. ? 2024 The Authors

Traditional electrical power grids are transitioning from centralised operation with unidirectional energy and information flows (from the generation domain to customers) to smart grids with decentralised mode of operation and bidirectional flows. This reversal of traditional power flow direction is due to the connections of active loads such as distributed energy resources (DERs) and renewable energy sources close to the distribution network. Through advanced and sophisticated information and communication technologies (ICTs), efficient DER management and various applications for reliable and secure power delivery are enabled. However, before the adoption of any ICT solution in the grid, several challenges remain, which include interoperability, security and privacy concerns, and the ever-increasing demands to support various services and applications. Although the information within the grid is becoming more visible because of bidirectional communication flow, this only applies to transmission networks and not active distribution networks, which house numerous smart grid applications. There is also little research that supports the automatic operation of active distribution networks. Hence, this article explores and reviews active distribution network communication technologies, as well as the applications and communication standards. This review paper also highlights issues and challenges with active distribution networks and opportunities and research trends in the distribution domain from an ICT perspective. � 2013 IEEE.

The Urban Heat Islands (UHI) effect is a microclimatic phenomenon that especially affects urban areas. It is associated with significant temperature increases in the local microclimate, and may amplify heat waves. Due to their intensity, UHI causes not only thermal discomfort, but also reductions in the levels of life quality. This paper reviews the important role of green infrastructure as a means through which the intensity of UHI may be reduced, along with their negative impact on human comfort and wellbeing. Apart from a comprehensive review of the available literature, the paper reports on an analysis of case studies in a set of 14 cities in 13 countries representing various geographical regions and climate zones. The results obtained suggest that whereas UHI is a common phenomenon, green infrastructure in urban areas may under some conditions ameliorate their impacts. In addition, the study revealed that the scope and impacts of UHI are not uniform: depending on peculiarities of urban morphologies, they pose different challenges linked to the microclimate peculiar to each city. The implications of this paper are threefold. Firstly, it reiterates the complex interrelations of UHIs, heat waves and climate change. Secondly, it outlines the fact that keeping and increasing urban green resources leads to additional various benefits that may directly or indirectly reduce the impacts of UHI. Finally, the paper reiterates the need for city planners to pay more attention to possible UHI effects when initiating new building projects or when adjusting current ones. � 2021 by the authors.

The rapid evolution of ICT has enabled several institutions to adopt Moodle as their preferred e-learning platform. Moodle is increasingly being used for interactive, personalised, and collaborative learning and improving online assessments. Despite Moodle's increasing popularity, there are limited reviews on the empirical evidence of its efficacy among students. The study aimed to provide an overview of the scientific literature on the studies that investigated the behavioural intention and actual usage of Moodle. This review shows that Moodle is mainly used in universities and effectively improves student performance, attitude, and satisfaction. Most studies that applied a theoretical ground applied the Technology Acceptance Model (TAM). Meanwhile, performance expectancy, effort expectancy, facilitating condition, perceived usefulness of professors, perceived ease of use, and subjective norms are essential drivers for online learning systems' acceptance or actual usage. These findings serve as evidence and reference for educational institutions in developing online learning policies and strategies. Further studies need to incorporate behavioural and motivational theories when designing Moodle courses. � 2023 NSP.

Thermophotovoltaic (TPV) technology harvests electricity from a source of thermal radiation and at current, TPV cells can achieve conversion efficiency of more than 40%. The construct of the TPV system is relatively complex than the conventional solar cell in which the TPV has two critical components, specifically the absorber-emitter and filters, to help in enhancing the transfer of photons to the TPV cell for conversion. Despite its importance, works on the optimization of these components for an ideal TPV system are still lacking. This review examines previous studies on the TPV structure, and details extensive techniques to improve current designs of the TPV systems - notably through the use of textured absorbers, selective emitters and different types of filters. Inevitably, the selection of materials and designs of the absorber-emitter are essential in enhancing the TPV performance. Herein, challenges and enhancements in the form of optical performance, thermal stability, and electrical performance are comprehensively discussed. This review identifies the crucial role of nanoparticles incorporated into the absorber-emitter layer of a TPV system. This review also critically highlights technology advancements incorporated into the TPV technology which will effectively boost performance and improve the fabrication and operational costs of this sustainable technology. � 2023 International Solar Energy Society

The rapid increase in population and widespread use of energy-consuming technologies are contributing to a substantial increase in the world's energy consumption. Supercapacitors have recently become a more desirable alternative due to their quick charging and discharging times, high power densities, and extended cycle lives. For many researchers, improving supercapacitor efficiency for multifunctional applications is a major area of study. Many elements have been employed as electrode materials to provide the best energy and power density while achieving the largest specific capacitance. Among these materials, 2D transition metal carbides and nitrides, commonly called MXenes, are emerging candidates, particularly in electrochemical energy storage applications. Because of their strength, flexibility, unique structure, increased electrical conductivity, large surface area, diversity of active sites, hydrophobicity, and hydrophilicity for cutting-edge energy storage technologies, MXenes are among the best active electrode materials. MXene, with its unique 2D layered structure, offers the infinite possibility of the intercalation of various capacitive materials. Also, MXenes have the properties of high hydrophilicity of metal oxides and high electrical conductivity of metals. Alongside, activated carbon (AC), graphene, carbon nanotubes (CNTs), transition metal oxides, and conducting polymers (CPs) act as excellent electrode materials owing to their outstanding thermal, mechanical, electrical, and morphological properties. According to recent studies, one of the perfect methods for energy storage applications is to integrate MXenes with other superior elements for generating MXene-based composite electrode materials. This review includes recent developments in the investigation of MXene-based hybrid composites for supercapacitors. It covers composite's synthesis strategies, electrode architecture, electrochemical performance, and their efficiency in supercapacitors. ? 2024 Elsevier Ltd

Magnetic field sensing is crucial for various scientific and technological applications, but current methods have limitations in cost, size, and weight. Fiber Bragg Grating (FBG) magnetic field sensors have emerged as a promising alternative, offering compact size, and simplified fabrication. This review introduces FBG synthesis methods and extensively discusses the three primary magneto-optic mechanisms for magnetic field sensing: Faraday effect, magnetic fluid, and magnetostrictive materials. We evaluate their advantages and disadvantages, with Faraday effect relying on the Verdet constant and facing complexity in measurement elements. FBG magnetic sensing with magnetic fluid shows promising sensitivity and versatility but is challenged by optical loss-induced errors. Magnetostrictive materials provide robustness but exhibit limited linearity. Future research should focus on addressing these challenges to enhance the reliability of FBGs for magnetic sensing. The findings highlight the exceptional potential of FBGs in advancing magnetic field sensing applications. � 2023 Elsevier Ltd

Pollution and increasing fuel prices are the main focus for governments today. The main cause of pollution is existing electricity power plants that use huge quantities of fossil fuel. A new strategy should be applied in the coming decades based on the integration of existing power plants with renewable energy sources, such as solar and wind energy. Hybridization of existing power plants with solar energy is one proven option to overcome the problems of pollution and increasing fuel prices. In this paper, a review of the previous studies and papers for integrating solar thermal energy with conventional and non-conventional power plants was carried out. The focus on hybrid solar conventional power plants includes: the review of studies of hybrid solar-steam cycle power plants, integrated solar combined-cycle systems (ISCCS) and hybrid solar-gas turbine power plants, while for hybrid solar non-conventional power plants the focus of study is hybrid solar-geothermal power plants. The most successful option is ISCCS due to their advantages and the plans for implementation at various power plants in the world like in Tunisia, Egypt, Spain, and Iran. � 2012 Published by Elsevier B.V.

With the sharp increase in global energy demand, industrial and residential buildings are responsible for around 40% of the energy consumed with most of this energy portion being generated by non-renewable sources, which significantly contribute to global warming and environmental hazards. The net-zero energy building (NZEB) concept attempts to solve the global warming issue, whereby a building will produce, on-site, its required energy demand throughout the year from renewable energy sources. This can be achieved by integrating photovoltaic (PV) building materials, called building-integrated photovoltaic (BIPV) modules, throughout the building skin, which simultaneously act as construction materials and energy generators. Currently, architects and builders are inclined to design a building using BIPV modules due to the limited colors available, namely, black or blue, which result in a monotonous building appearance. Therefore, there is an increasing demand/need to develop modern, aesthetically pleasing BIPV green energy products for the use of architects and the construction industry. This review article presents the current stage and future goal of advanced building integrated photovoltaic systems, focusing on the aesthetically appealing BIPV systems, and their applications towards overcoming global challenges and stepping forward to achieve a sustainable green energy building environment. Additionally, we present the summary and outlook for the future development of aesthetically appealing building integrated photovoltaic systems. � 2023 by the authors.

This paper proposes an Agent-based Document Classification (AbDC) model that computerizes the systematic literature review (SLR) process by imitating what a researcher is supposed to perform during the literature review process manually. The AbDC model comprises three main components that perform the SLR. Firstly, the document classification algorithm analyses a full text of research articles and evaluates relevancy. Secondly, the multi-agent architecture accelerates the mining process and handles the performance issues. Finally, the web-based systematic review tool tests and validates the functionality of the proposed AbDC model. The first testing was conducted to assess the performance of the proposed AbDC. Result shows that the required processing time was reduced by 33.5% using four agents to achieve the mining process. Meanwhile, the second testing was performed to validate the mining process results. The text extraction method was run on 200 documents from various studies to conduct the review process. The parsing process yielded valid results with 98.5% accuracy. The testing results showed that the proposed AbDC model is significant in providing researchers and postgraduate students with new means to perform SLR. � 2022 Little Lion Scientific
