“…The main limitation of PV systems is their low conversion efficiency influenced by their operating temperature [198,199]. For that reason, different thermal regulation techniques were proposed over the last years to overcome the adverse effects of high temperatures on PV panels, including NEPCMs [47,[200][201][202][203].…”

“…A prospective replacement for these energy sources are renewable energy sources such as wind, solar, and geothermal. Solar energy has received further attention among the various kinds of renewable energy because it is limitless and widely available [1]. In the last two decades, two main solar systems have been introduced for converting solar irradiation into heat and electricity for use in different residential and industrial applications.…”

“…To tackle these problems and improve the performance of these systems, different enhancement methods are applied. As an example, some researchers have investigated the effects of adding nanofluids to WF [6], using turbulators through WF [7], employing phase change materials [8], a combination of these methods [1], and applying concentrators [9]. It should be mentioned that each improvement technique has its drawbacks.…”

The annual performance of a hybrid system of a flat plate photovoltaic thermal system and a solar thermal collector (PVT/ST) is numerically analyzed from the energy, exergy, and environmental (CO2 reduction) viewpoints. This system can produce electricity and thermal power simultaneously, with higher thermal power and exergy compared to conventional photovoltaic thermal systems. For this purpose, a 3D transient numerical model is developed for investigating the system's performance in four main steps: (1) investigating the effects of the mass flow rate of the working fluid (20 to 50 kg/h) on the temperature behavior and thermodynamic performance of the system, (2) studying the impacts of using glass covers on the different parts of the system, (3) evaluating the annual energy and exergy analyses of the system under Mashhad weather conditions, and (4) examining the CO2 reduction by using the proposed system. The results show that for the (glazed) PVT and (glazed) ST systems, increasing the mass flow rate of the working fluid from 20 to 50 kg/h results in 22% and 1.5% improvements in both thermal and electrical power, respectively. However, the thermal exergy of the system decreases by 40.1%. Furthermore, the (glazed) PVT/(glazed) ST systems generate approximately 86% and 264% more thermal power and energy than the PVT/ST systems, respectively. Using a (glazed) PVT/(glazed) ST system with a working fluid’s mass flow rate of 50 kg/h results in maximum thermal and electrical efficiencies of 40.7% and 16.22%, respectively. According to the annual analysis, the highest average thermal and electrical power, equal to approximately 338.3 and 24 W, respectively, is produced in August. The amount of CO2 reduction increases by increasing the mass flow rate and using a glass cover. The PVT/(glazed)ST system has the potential to reduce CO2 emissions by 426.3 kg per year.

“…One of the most commonly used systems for this purpose is a photovoltaic thermal (PV/T) system, which generates electricity via solar cells and thermal energy via a heat transfer fluid at the same time. [1][2][3][4] The significant advances in PV/T research over the past decade show a substantial improvement in solar energy conversion performance. The utilization of air, 5,6 water, 7,8 nanofluid, [9][10][11] and phase change materials 12,13 for PV module cooling and waste heat recovery enhances the PV/T system efficiency.…”

Summary Nanofluid spectral splitting photovoltaic thermal (PV/T) systems have become immensely common for the utilization of full‐spectrum. The performance enhancement investigation of the plasmonic hybrid nanofluid spectral filtering PV/T system in dynamical modeling and a practical validation was carried out in this study. The Ag@SiO2 core‐shell nanoplate/ethylene glycol‐CoSO4 plasmonic hybrid nanofluid was synthesized to selectively absorb incident natural sunlight. We used H2O2 as a basic shape‐selective oxidant to synthesize the silver nanoplate using a one‐step method. This approach simplifies seed formation and transformation of spherical nanoparticles to different‐sized nanoplates. A practical study of the plasmonic hybrid nanofluid optical filtering PV/T system was conducted outdoors on sunny days to represent the temperate region and evaluate the dynamic modeling and the system's applicability in real situations. It was found that the plasmonic beam splitter serves as an efficient heat transfer medium and maintains the PV module around the ambient temperature. The highest temperature recorded on the typical day of our experiment was 51.62, 54.34, and 57.56°C for the ethylene‐CoSO4 base fluid and nanofluids with concentrations of 18.3 and 28.3 ppm, respectively, and 33.16°C for the PV panel. The highest overall performance of up to 87.6%, 86.4%, and 85.3% was attained by the spectral filtering plasmonic hybrid nanofluid PV/T system using a 27.3 and 18.3 ppm concentration ratio and hybrid base fluid, respectively. The study shows the nanofluid reduces the electricity output but produces higher merit function values than the PV standalone. This shows that the proposed nanofluid is a potential candidate for PV/T systems targeting utilization of full‐spectrum sunlight and enhancing the overall performance.
