| الملخص: | Recently, solar energy research popularity has been growing rapidly due to its pollutant-free renewable energy source. As an alternative energy to the existing conventional fossil resources, solar energy is projected to drive the future research to a new level in renewable energy field. One of the methods to harvest the solar energy is through the solar thermal collector, which utilizes heat transfer fluid to capture the solar radiation. In this paper, a recent development of application using concentrated direct absorption solar collector on nanofluids is comprehensively discussed. Our emphasis is on concentrating solar collector including parabolic trough, parabolic dish, heliostat field collector and Fresnel solar collector. To accomplish this, an inclusive review on the analytical, numerical and experimental studies in this field is prepared. Finally, some issues related to the concentrated direct absorption solar collector using nanofluid are also presented. © 2019, Akadémiai Kiadó, Budapest, Hungary.
