In this work, the thermoelectric generator (TEG) layer has been combined with conventional layers of photovoltaic-thermal (PVT) modules to use the waste heat and increase the efficiency. To reduce the cell temperature, there exists a cooling duct in the bottom of the PVT-TEG unit. Type of fluid within the duct and structure of duct can change the performance of the system. So, hybrid nanofluid (mixture of Fe3O4 and MWCNT with water) has been replaced instead of pure water and three various configurations of cross section [STR1 (circular), STR2 (rhombus), STR3 (elliptic)] have been implemented. Through the tube incompressible laminar flow of hybrid nanofluid has been solved while in solid layers of panel, pure conduction equation has been simulated involving heat sources resulting from optical analysis. According to simulations, the third structure (elliptic) has the best performance and rise of inlet velocity causes overall performance to enhance about 6.29%. The values of thermal and electrical performances for elliptic design with equal fractions of nanoparticles are 14.56% and 55.42%, respectively. With the best design, electrical efficiency improves about 16.2% in comparison with an uncooled system.

“…F, Figure 44. The solar PV-T collector system [122] Chi et al proposed 1-, 2-, and 3-direction-automatic-rotation (1-DAR, 2-DAR, and 3-DAR) vertical sun-tracking shading panel arrays placed on the southern wall of the office building and concluded that the shading panel array integrated with the automatic rotation control method simultaneously prevented sun glare [123]. For the first time, Anctila et al demonstrated the net energy benefit of transparent PVs in building applications, using a life cycle approach that is thought of as a change in electricity generation and building performance [124].…”

The need for energy sources in the world is gradually increasing day by day. Photovoltaics (PVs) usage has worldwidely spread thanks to the efficiency and reliability increase and price decrease of solar panels. The photovoltaic (PV) glazing technique is a preferred method in modern architecture because of its aesthetic properties besides electricity generation. Traditional PV glazing systems are mostly produced from crystalline silicon solar cells (c-SiPVs). The development of low-cost PV cells for the production of costeffective and energy-saving glass systems has been of great interest. Solar control glass which is one of the crucial components of PV panels is largely employed for architectural and automotive windows to lower the sunlight and heat inlet for the comfort. Hereby a general overview of solar glass panels is presented.

“…The effect of operating conditions on the performance of the PVT systems is also studied extensively [36]. It is observed that a higher mass flow rate of the working fluid, Lower inlet temperature, moderate solar irradiance, high wind speed, and lower ambient air temperature leads to better performance [5,37].…”

Although, the effect of mass flow rate and solar irradiance variation is present in literature, it is still of significant interest to investigate the extent of the effect especially when utilizing a custom absorber design. In this paper, the effect of changing the mass flow rate and solar irradiance on the performance and temperature uniformity of a PVT using a custom spiral absorber design is simulated using ANSYS CFD software. By increasing the mass flow rate, the temperature uniformity and the performance parameters such as the average PV temperature, water outlet temperature, thermal and electrical efficiency all increase. By increasing the irradiance level, performance and temperature uniformity drop albeit at a smaller degree compared to change observed in mass flow rate variation. Amongst the tested range, the optimum mass flow rate and solar irradiance levels for best performance are 40 kg/h and 800 – 1000 , respectively.
