Photovoltaic Thermal (PVT) with Advanced Tube Design and Working Fluid - A Review

This paper reviews the state-of-the-art cooling classification methods for photovoltaic system (PVs) modules and evaluates water or nanofluid, in details, the performance of radioactive cooling method. This review also covers the future development of absorber tubes photovoltaic thermal collector PVT. Daily heat budgets of PV modules with different absorbed tubes used in solar cells to reduce the temperature of the surface were analysed. This paper provides an overview of the various solar absorber tubes of Photovoltaic thermal (PVT) collector technologies, including their efficiencies, benefits, drawbacks, and research opportunities. The results show that the shape and diameter of the tube, the mass flow rate and the working fluid improved the total efficiency for the PV cell.
