For a sustainable system to be designed with the lowest possible cost, photovoltaic thermal (PV/T) system efficiency and heat transmission must be increased. The performance of each hybrid PV/T air system was examined using four air PV/T models with various geometric configurations. The examination of the various mathematical models revealed how each geometry configuration affected each system's performance. Air PV/T arrangements with expanded surfaces, like fins, enhance thermoelectric performance. According to the findings, the thermal efficiencies of finned absorber PV/T and finned Tedlar PV/T are, respectively, 80.3 and 77.54%. Additionally, the figures for electrical efficiencies are 11.88 and 11.93%, respectively. For these two types of PV/T systems, the annual energy output has increased and now stands at roughly 3242 and 3316 kWh/m2, respectively. Additionally, compared to other PV/T systems, the finned Tedlar PV/T system offers higher profitability in terms of cost and revenue according to an economic research.

The hybrid photovoltaic-thermal system has shown great progress. Electrical energy is produced from PV panels while thermal energy is produced via a working fluid carried through the panels. In this paper, the vertical PV/T is introduced using working fluids such as air and liquid, which serve to control the excess temperature of the PV panels as well as to collect heat to be made available as thermal energy. Installations of PV/T systems on building façades, as well as integration with other technologies such as heat pipe and heat pump are also discussed. Current studies of such building integration technologies are also explored, including the scale of application. This study aims to provide constructive information which can be used in future development of building facades for large-scale applications, to contribute to future sustainable development. Practical application: This study helps researchers and engineers who are considering photovoltaic thermal systems for building façades to have better understanding of its effect on electrical and thermal energy – for space heating, fresh air supply and hot water supply – using an active building envelope.

“…In this study, 15 channels were described as optimal for receiving the maximal amount of energy efficiency. Fan et al [24] investigated the dynamics and solving of governing equations using the Crank-Nicolson method for a PV/T system similar to reported data [22,23], which are connected to a solar-powered air heater in series mode. They finally compared the response of modeling the system stable state and dynamical mode-modeling and reported that a stable state response could well predict the behavior of the system.…”

“…Jin et al [22] experimentally investigated two PV/T systems including a heat converter with parallel rectangular channels and with a flat panel air collector using air-fluid medium They reported in different flow rates, the optimal flow rate was 0.0287 kg/s to achieve maximum efficiency. Tabet et al [23] used a heat converter similar to reported data [21,22], out of 5, 10, and 15 flow channels to analyzed a PV/T system with airfluid medium. In this study, 15 channels were described as optimal for receiving the maximal amount of energy efficiency.…”

“…To overcome the mentioned shortages, in this research the development of static modeling and a novel accurate solution of a MCPV/T system with multi-flow channels as well as validation of the equations obtained with experimental results have been considered which is completely different from the numerical method stated in literature [22][23][24]. The contact of air to the back surface of Tedlar PVF Film is direct and a novel fan positioning is considered in the middle of the system.…”
