This paper reviews solar selective films, that is, solar selective absorbers and solar selective transparent filters which are necessary for the utilization of solar thermal energy. The optical characteristics required for the solar selective films is described and the notion of the efficiency in the solar selective films is introduced. Many solar selective absorbers and transparent filters which have been proposed and fabricated up to the present are classified according to the mechanisms by which these films work and some examples are shown. The evaluation of the efficiency and the durability of the fabricated solar selective films is described.
