“…[3,8] This truth in application has led to some research looking into hydrogenated amorphous Silicon (aSi:H) being used for the PV components as opposed to traditional mono or polycrystalline Silicon (c-Si), as the temperature coefficient for a-Si:H is typically 0.01% per Kelvin [5] compared to the c-Si value of 0.04% per Kelvin. [1][2][3][4][5][6][7][8][9][10] This is also due to the fact that a-Si:H can operate at a higher temperature, allowing the thermal working fluid to be raised to a higher temperature as well since the Second law of Thermodynamics dictates that heat can only go from a hotter body to a colder one. [5] High temperature conditions also cause accelerated degradation of the photovoltaic system through the means of thermally activated degradation processes, which include polymer degradation and collector contact corrosion.…”

“…[1] It has also been hypothesized in PVT design that the glass cover may also be reflecting light from the cell and lowering some of the electrical efficiency and thus some thermal efficiency as high energy light bouncing off the front panels are simultaneously not creating electron-hole pairs and thermal energy from relaxation processes.…”

“…It is this electron liberation process that is used as electrical energy in all solar powered systems, by creating metal contacts between negative (electron donor) and positive (electron acceptor) type semiconductors to create a circuit. [1][2][3][4][5][6][7][8][9][10][11] Conversely, light that does not have sufficient energy does not interact with the PV component, passing it and thus being collected by the thermal backplate. The backplate also collects radiative heat from the thermal relaxation of promoted electrons that absorbed photons of light larger than Eg that are preparing to recombine in the PV component of the system.…”

“…Not only does this collection method increase the spectral efficiency of the collection system as a whole [1][2][3][4][5][6][7][8][9][10][11], but the thermal component by nature acts as a heatsink for the photovoltaic component. This allows PVT systems to double down on efficiency gains, as higher thermal output means lower PV operation temperatures, which increase PV collection efficiency as well.…”

Photovoltaic/Thermal hybrid (PVT) systems have shown promise as a viable commercial and private source of renewable energy. The purpose of this meta study is to combine contemporary research findings in the area of Photovoltaic (PV) and Photovoltaic/Thermal Hybrid solar systems and attempt to offer general optimisation principles for future PVT devices. Design parameters with which we attempt to optimise through will include PV material choice, CPC inclusion and system temperature optimisation for operational lifetime gain and power yield. It was found that we can combine CPC, closed glass design, spiral web flow and m>0.003kg/s to optimise the c-SI based systems and obtain an overall PVT efficiency gain of 5.5±1.6%, and that mass flow rates exceeding 0.003 kg/s can increase longevity by 80% on average and increase electrical efficiency by 1.2% when compared to conservative lower mass flow rates. Hydrogenated amorphous silicon systems were also deemed to create less high-quality energy and overshooting required thermal needs when using personal/private power statistics as selection criteria.

“…As for the absorber it may have different designs and shapes as well such as rectangular, round and square shapes, also web flow, direct flow, spiral flow, oscillatory flow, serpentine flow, parallel serpentine flow and modified serpentine-parallel flow designs. These systems could also have single passing or double passing [36][37][38][39][40]. This paper aims to revise and review research articles core related to PV/T systems in order to find critical points that can be either enhanced in the future.…”

Abstract-Photovoltaic Thermal (PV/T) combine the solar thermal and photovoltaic systems. This technique benefits from both light and heat of the solar radiation to produce electricity and hot fluids. Research in PV/T systems is rapidly growing with more methods and techniques to increase the overall efficiency, reduce the cost, improve the modeling, and maintain the system for long periods of time and employing them for suitable application. The paper aims to study some of the research conducted in this field in order to understand and derive key points to producing more research and providing constructive criticism for the work presented. Also a detailed explanation of PV/T systems' principles and operation is presented. Classifications of PV/T in terms of absorber design, shape of pipes, PV configuration, type of working fluid (base-fluid) and type of PV panels are all discussed in the literature survey. Finally, it is concluded that there is a clear lack in electrical, economic and environmental evaluations, where most of articles in PV/T are dominated by the thermal study of the system.

Photovoltaic technology plays a crucial role in harnessing renewable energy. While photovoltaic panels directly convert solar energy into electricity, more than 50% of solar radiation is lost as waste heat, diminishing the overall efficiency of the panels. This study reviews various cooling technologies for photovoltaic systems, focusing on the use of phase change materials for cooling in photovoltaic systems. Phase change materials, known for their high latent heat capacity, are extensively used in thermal energy storage applications. Incorporating phase change materials in photovoltaic systems can increase thermal storage potential by 30–50% compared to conventional systems, leading to a 70% extension in heat storage duration and various levels of enhanced power output. The main purpose of the article is to review the advantages and disadvantages of various technologies, determine the research direction of phase change materials for cooling systems in photovoltaics, and ensure the reliability of this technology.
