This paper gives a comprehensive overview about the recent advances related with the application of the
nanotechnology in various kinds of the solar collectors. Papers reviewed including theoretical, numerical
and experimental up to date works related with the nanotechnology applications in the flat plate, direct
absorption, parabolic trough, wavy, heat pipe and another kinds of the solar collectors. A lot of literature
are reviewed and summarized carefully in a useful tables (Tables 1–7) to give a panoramic overview
about the role of the nanotechnology in improving the various types of the solar collectors. It was found
that the use of the nanofluid in the solar collector field can play a crucial role in increasing the efficiency
of these devises. We think that this paper can be considered as an important link between the nanotechnology
and all available kinds of the solar collectors. From the other side, further researches are
required to study the effect of nanotechnology to enhance the solar collector industry over the next
several coming years.
