Abstract: PURPOSE: A quantum dot sensitive solar battery and a manufacturing method thereof are provided to easily recover the supercritical fluid or the subcritical fluid including unabsorbed quantum dot precursor. CONSTITUTION: A quantum dot precursor(60) is introduced within a high pressure reservoir(11), and is dissolved by using the subcritical fluid or the supercritical fluid. The manufactured quantum dot precursor solution is transferred to a conductive film substrate(61) consisting of metal oxide introduced within the high pressure reactor, and is absorbed in metal oxide thin films. The quantum dot precursor solution which is not absorbed is transferred with the subcritical fluid or the supercritical fluid to the high pressure reservoir and recovered. The subcritical fluid or the supercritical fluid in a gas phase is eliminated from the high pressure reactor. The adsorbed quantum dot precursor is reacted with the compound including the second element forming the quantum dot.
