  4. Abstract:
  5. Hybrid nanofluids have several advantages compared with the conventional types due to their modified properties. Their enhanced thermophysical and rheological properties make them more appropriate for solar energy systems. In this review paper, an overview of solar energy systems is represented, and afterwards, applications of hybrid nanofluids in various solar technologies, especially solar thermal, are reviewed. Comparison between the nanofluidic systems, and the conventional ones is performed in order to gain a deeper insight into the advantages of using nanofluids. According to the results of the reviewed studies, the most important reason for performance enhancement of nanofluidic solar energy systems can be attributed to the improved thermal properties of the convective fluid. In addition, it can be concluded that the nanofluids’ specifications such as concentration of the nanostructures, type of the solid phase, etc., have significant impact on the behavior of the considered systems. © 2019 Elsevier B.V
