“…When a refrigeration unit is installed at the rear of the solar cell, the heat transfer area increases according to the surface area of the refrigeration unit that is in contact with the collector fluid. Increasing the heat transfer area will increase the rate of convection heat transfer from the photovoltaic solar cells to the collector fluid and reduce the solar cells' operating temperature [ 79 ]. Cooling down the fluid at the highest radiation intensity of 1000 W/m 2 to reduce the working temperature and increase solar cell performance.…”

“…Aluminum is more affordable and easier to find. In addition, it allows for perfect bonding between photovoltaic laminates or laminates, thereby increasing the heat transfer of photovoltaic solar cells [ 79 , 81 ]. The use of collectors with direct flow designs is easy to manufacture and assemble in photovoltaic thermal collector systems.…”

“…The general assumption, mainly in modeling studies, is that the back layer of the PV panel (tedlar) is well connected to the thermal collector. However, a poor connection between the thermal collector and the PV panel can reduce the electrical performance of the PVT panel because the PV cell temperature tends to be higher, thus lowering the PV cell's efficiency [1]. The bonding quality between the PV panel and the thermal collector greatly determines the thermal performance of the PVT.…”

Photovoltaic thermal (PVT) systems promise a more optimal solar energy utilization by producing electricity and heat simultaneously. However, the thermal collector design and the way it is connected to the PV panels are still a problem for the PVT system. This study aims to answer the use of thermal paste and insulation in thermal collectors are some of the issues in PVT system manufacturing. An experimental study was conducted by making three scenarios of thermal collectors combined with PV panels and then tested in an indoor solar simulator. Each design was tested with five different cooling water flow rates. This study found that thermal paste and insulation can improve the electrical power of PVT systems by up to 17.59% and its thermal performance increase by 10.13%. Thus, the use of thermal paste and insulation should be done in the manufacturing of each thermal collector for PVT systems.

“…There are currently several types of cooling systems for PV modules, classified according to the author and level of development of the technologies [41][42][43], but they are mainly distributed into two major groups: (i) closed-circuit cooling system, in which the fluid circulates in a thermal collector, exchanging heat with the PV module, that is, in a confined environment [44][45][46]; and (ii) open-circuit cooling system, in which the fluid is directed at the PV module, running through its area in an unconfined manner, without the aid of pipes, ducts, chambers, etc., that is, in direct contact com with the environment [47][48][49][50][51][52][53].…”

This work aims at analyzing and architecting natural and artificial parameters to model a water-film cooling system for photovoltaic modules for some months under warm conditions. Methodologically, the theoretical and technical aspects were structured to develop, implement, monitor, and assess the cooling system at an on-grid, outdoor testing unit, considering the following: (i) the criteria to select and to approve the implementation site (infrastructure and climatologic and solarimetric conditions); (ii) the types, frequency and qualities of the monitored data; (iii) the system measurement, monitoring and control equipment; (iv) the commissioning of the system as a whole; and (v) the tests and results empirically obtained. The water-film cooling system reduces the temperature by 15–19%, on average, and up to a maximum of 24–35%. In terms of electric power, there was an average gain of 5–9% at the time of day with the highest solar radiation, and maximum gains of 12% on days with solar radiation above average. Regarding gross energy, average gains of 2.3–6%, and maximum gains of 6.3–12%, were obtained. It was concluded that the test unit helps understand the natural phenomena and the development, operation, and maintenance of performance gain systems of on-grid PV modules for construction on a commercial scale.
