“…Ho et al 139 used a mathematical simulation of a PV/T system that uses two PCMs in two envelopes and bound together behind the photovoltaic panel as an integral part of it and floats on the surface of a water tank as shown in Figure 15 From reviewing the last section: The electrical efficiency of PV/T-PCM systems increases by 15.0% to 23.0% compared to a single solar panel, 128,133 and the addition of PCM to the PV/T system has significantly enhanced electrical efficiency compared to the cooling capabilities of single-lane fluids or two passes. 132 Electrical efficiency with PV-MEPCM increased by 2.1% when compared with the PV-PCM system, as stated by Reference 138. The thermal efficiency increased when using PV/T-PCM systems with many types of PCM, for example when using uric acid, it was increased up to 90.0%, 129 and it was increased by 69.8% when working with Capric acid, 140 and increased by 72.0% when using Silicon Carbide (SiC) nanofluid and SiC dispersed with paraffin wax.…”

Summary The use of photovoltaics has spread widely, and government agencies have begun adopting plans to deploy plants with large capacities, due to their environmental friendliness, low manufacturing costs, and high productivity. In the sunny countries where this technology should spread, the photovoltaics' energy conversion efficiency decreases due to the high temperature of which the cell's operate at; because a large part of the solar radiation is absorbed by the solar panels as heat, while the smaller part converts it to electricity. From here, the benefit of the shift towards the PV/T technology that works to reduce the photovoltaic modules temperature and improve their electricity produced along with yielded thermal energy which can be utilized in other applications. In this study, a thorough review of many recent research and studies published in the field of PV/T has been carried out. The present study was divided into several sections to clarify and focus on the effect of each technology separately. Researchers used one or more fluids to cool the solar panels, and their research dealt with many of these fluids, starting with air, water, oil, etc. Other researchers have tended to increase the thermal conductivity of liquid cooling fluids by adding many types of nanoparticles with high thermal conductivity. Other researchers have used variable‐phase materials to take advantage of the large storage of the latent heat of these materials. Other researchers have studied improving heat transfer of PCMs by mixing it with nanomaterials with high thermal conductivity. Others have also combined nano‐PCMs and nanofluids together in one system, and they have demonstrated, in theory and practice, that this technique exhibits higher energy collection and utilization than the other types of PV/T. At the conclusion of the study, some critical points are identified that work is still limited and needs more research efforts and studies.

Phase change materials (PCMs) are used as latent heat thermal energy storage materials. The fields of application for PCMs are broad and diverse. Among these areas are thermal control of electronic components and thermal building regulations. These areas are used as heat and cold storage materials. The low thermal conductivity of PCMs is one of the significant and severe technological problems of PCMs. This paper presents a review of the latest works using PCMs in the thermal management of electronic components, buildings, and heat exchangers. Besides, it provides concise pieces of information on the classification of PCMs, their advantages, disadvantages, and thermal storage systems.

“…Many studies have been carried out to develop different materials for the construction of panels, generating less waste and also not allowing the system to overheat (Letcher, 2018;Salameh, New York, & Diego, 2014). From the irradiation incident on the photovoltaic module, only 15 to 20% is converted into electrical energy, hence the great efforts and studies to improve the performance (Fayaz et al, 2019). For wind power to be considered technically feasible, a minimum wind velocity of 7 to 8 m/s is required (Poole et al, 1993).…”

PurposeThis paper aims to point out the scientific development and research density of renewable energy sources such as photovoltaic, wind, and biomass, using a mix of computational tools. Based on this, it was possible to verify the existence of new research trends and opportunities in a macro view regarding management, performance evaluation, and decision-making in renewable energy generation systems and installations.Design/methodology/approachA scientometric approach was used based on a research protocol to retrieve papers from the Scopus database, and through four scientometric questions, to analyze each area. Software such as the Science Mapping Analysis Software Tool (SciMAT) and Sci2 Tool were used to map the science development and density.FindingsThe scientific development of renewable energy areas is highlighted, pointing out research opportunities regarding management, studies on costs and investments, systemic diagnosis, and performance evaluation for decision-making in businesses in these areas.Research limitationsThis paper was limited to the articles indexed in the Scopus database and by the questions used to analyze the scientific development of renewable energy areas.Practical implicationsThe results show the need for a managerial perspective in businesses related to renewable energy sources at the managerial, technical, and operational levels, including performance evaluation, assertive decision making, and adequate use of technical and financial resources.Originality/valueThis paper shows that there is a research field to be explored, with gaps to fill and further research to be carried out in this area. Besides, this paper can serve as a basis for other studies and research in other areas and domains.
