In this paper, a comparison was made between two types of PV modules widely used in the market: polycrystalline and thin-film (both of them are silicon-based manufacturing) to identify the variables and parameters affecting the efficiency of solar cells. The efficiency of polycrystalline is higher than thin-film, although the open circuit voltage is more affected by solar radiation. The comparison was made in Gödöllő in Hungary, characterized by a moderate climate temperature and humidity on a partly cloudy day to study the effect of clouds and the change in the amount of solar radiation on solar cells. The flexible feature of thin-film cells can be used in many applications, especially those related to covering surfaces, as it is considered thin-layer and does not require an expensive metal structure to install. All these variables were calculated and discussed. The difference between the efficiency of polycrystalline and thin-film modules was a small percentage ranging between (-0.2% to 0.5%). This difference comes from the manufacturing technology method and the manufacturing quality itself.

“…The primary object was to enhance energy production. Various parameters were studied to investigate the hybrid schemes behavior based on different approaches applied in the simulation processes [9,10]. In this context, the author in [11] used Matlab simulation to validate the water-cooled unit with the outdoor conditions model.…”

An evaluation of the performance of the Iraqi environments in terms of electrical, thermal and exergy efficiency is introduced in this study. The research is carried out in May 2022, in the Baghdad metropolis. The extraction process of heat from the photovoltaic units which arises from the coolant liquid mass flow rate deem as an essential point. The experimental studies were implemented by absorbing heat energy behind from the photovoltaic cell's surface in insulated conditions and using a cooled water unit. The results indicated that at a mass inflow rate of 0.2 kg/sec, the maximum average total efficiency of the system was recorded 22%. As a result, it is advised that to reduce the payback interval, it is possible to design efficient solar photovoltaic–thermal systems to promote the whole system's efficiency and lower the payback interval.

This study presents the effect of cell temperature on the hybrid solar collectors PV/T for modules with and without using a front glass cover. A numerical model of thermal behaviour was carried out for glazed (PV/Tg ) and unglazed (PV/Tun) modules. As a result of this experimental investigation conducted for presented PV/T modules, a sufficient decrease in the cell temperature of PV/Tun compared to the PV/Tg, PV/Tun module exceeded the PV/Tg by 19%. Thus, the electrical productivity of the PV/Tun module was higher; it was 3.44% higher than the PV/Tg value. The outlet liquid temperature of the un-covered module was 6.34% higher than the outlet liquid temperature of the glass-covered module. Besides, the total efficiency of the PV/Tg was higher during the periods of study. In this sense, the glass-covered module is preferable for applications that deal with overall efficiency as a desirable factor. The un-covered module is much beneficial for applications that need high electrical productivity.
