Hybrid photovoltaic/ thermal systems are very promising clean energy harvesting devices where they can be used either standalone system or can be incorporated with other systems. In this study, historical developments leading to current Hybrid Photovoltaic/Thermal (HPV/T) systems as it is used today and global findings to enhance the performance of HPV/T system through state-of-the-art analyses are presented in a thematic way. The findings from initial studies on the HPV/T systems is revealed in an historical way and rest of sections are formed based on selected criteria. The paper covers basic and advanced type collectors, working fluids, analyzing methods to assess performance, thermodynamic approaches, optimization of design parameters and mass flow rates, techniques to enhance performance and comparative studies. Especially, various parametric studies to optimize performance of the HPV/T with respect to selected parameters including different types of absorbers, packing factor, cooling schemes, working fluid types, modifications at different sections of the system are comprehensively investigated. Based on the conclusions, the variation in electrical and thermal efficiencies are mainly in the scope of this study. It is observed from the literature that solar HPV/T system has a great potential to be one of the up and coming clean energy technology.

In the current paper, the performance of an externalfin-assisted thermosyphon is investigated experimentally. The thermosyphon is produced with a copper tube and includes three parts-the evaporator, the adiabatic, and the condenser. The condenser part is enhanced with external longitudinal fins. In this study, different number of fins, filling ratios (FRs), coolant flow rates, a wide range of heat inputs, and initial absolute pressures are considered. The experiments are carried out by measurement of temperature distribution of the thermosyphon's wall and the temperature difference of the coolant. The results depict that increasing the heat input and FR reduces the thermal resistance, while raising the coolant flow rate augments the thermal resistance. Adding external fins to the condenser causes further condensation, which enhances the thermosyphon thermal performance by a reduction of 26.32% in thermal resistance and an increment of 28.55% in the thermosyphon efficiency.

Summary A novel hybrid PVT/parabolic trough concentrator (PTC)/organic Rankine cycle (ORC) solar power system integrated with underground heat exchanger has been proposed. The evaporator unit consists of a transparent flat PVT solar collector and a PTC connected in series. The first transparent solar collector has transparent covers and consists of solar cells totally immersed within a pressurized transparent organic fluid that allows the solar radiation to reach the solar cells, cools them effectively, and captures all thermal losses from the solar cells. The second concentrator is a conventional one with opaque black receiver used to reheat the transparent organic fluid to higher temperatures. Both solar collectors (the PVT and PTC) perform as the boiler and superheater for the ORC. The performance of the proposed system is investigated by a steady‐state mathematical model. The results show that, at design conditions, the efficiency of the PV modules stabilizes around 12%, absorber efficiency varies within 64% to 75%, and the ORC efficiency varies within 7% to 17%.
