“…Thus, solar energy utilization is maximized when the solar PV is hybridized with an STC into a hybrid photovoltaic-thermal system (PVT). Consequently, the PVT increases the overall efficiency by converting solar energy into electricity [19], heat, or both electricity and heat [20].…”

Solar energy as a non-fossil alternative energy source has become the best choice to overcome the problem of energy demand in most countries in the world. There are two different techniques to convert solar energy: photovoltaic (PV) panels to produce electricity and thermal collectors to generate heat. The two technologies can be combined to provide electrical and thermal energy either simultaneously or separately. In order to optimize the performance of a hybrid photovoltaic-thermal (PVT) solar air heater, it is necessary to collect experimental data on solar irradiation and temperature. This paper emphasized the development of a PVT energy system for hot air production in a temperature range of 50-55 °C. Additionally, experiments were constructed to monitor the information acquired from the proposed PVT solar air heater and the environment, such as hot air temperature, ambient temperature, and solar irradiation. The real-time monitoring system was set for five sample days. A microcontroller unit was used to control the hot air temperature and save the measurement data into memory. The experimental results showed that the proposed PVT solar air heater is capable of maintaining a certain level of hot air temperature throughout the day and night.

“…Although the direct cooling system has high thermal performance, it is not considered as practical solution for the battery packs especially in the presence of heat transfer fluid. 58,66 The indirect liquid cooling system has more advantages over the direct liquid cooling system, where it has higher flow rate with fixed pumping power, because the used coolants (e.g. CuO/water nanofluid) have lower viscosity than dielectric liquids which are used in the direct liquid systems, also the indirect system is easier to implement.…”

This paper presents a comprehensive review on the battery especially Lithium-ion batteries and the battery thermal management systems for electric vehicles. The basics of the battery system and thermal issues related to the battery have been highlighted. Different battery thermal management systems have been discussed in the review. This paper has presented different thermal management systems for electric vehicle battery in details. Air cooling, phase change, and liquid cooling are studied in the reviewed literature, by showing and discussing the results of the previous studies in these fields. Most promising thermal management system is the liquid cooling, because it has the best cooling potential for the EV batteries which gets the researchers attention to improve it based on wide number of increasing studies and developments in the EV liquid cooling systems. Improving the hydraulic and thermal performance of the liquid cold plate which is part of the EV liquid colling systems has not widely been explored in the fields of developing inlets design, outlets, and fins. The review paper could guide the researchers to innovate better liquid cooling systems and improve their cooling and hydraulic performance in battery thermal management systems.

“…For performance stability, converting heat into valuable energy can control the PV module temperature. That is one of the reasons for combining a PV module with a thermal collector into a hybrid photovoltaic-thermal (PVT) collector [5]. The conversion of solar energy is up to 80-90% [6].…”

Module temperature has a role in determining a PV module's performance. The purpose of this paper is to estimate the Joule heating in a photovoltaic (PV) module by comparing during PV-On (electricity generation) and PV-Off (without electricity generation). Joule heating was less evaluated due to simplifying formulation, which is easier to implement in experimental observation as proposed in this work. The experiment collected the temperature distributions of the PV module during PV-On and PV-Off. PV module temperature distribution follows the normal distribution curve as the irradiation uniformity pattern of the solar simulator has a slight ≤0.3 oC difference between PV-On and PV-Off. Joule heating slightly increased the PV module temperature by 0.53 K/A, proportional to the irradiances. Joule heating has increased almost seven times from 2.65 W at 700 W/m2 to 18.07 W at 1000 W/m2. Joule heating might slightly increase the overall thermal conductivity and slightly decrease the thermal resistances. It might affect the heat transfer. This research may improve the procedures prediction of PV or photovoltaic-thermal (PVT) collector temperature by considering Joule heating.
