PROBLEM TO BE SOLVED: To provide a method of manufacturing a quantum dot sensitization solar battery capable of adsorbing a quantum dot to a photoelectrode in a short time while keeping a good photoelectric conversion rate.SOLUTION: A quantum dot sensitization type solar battery has a photoelectrode 12 having an oxide semiconductor layer 21 formed on a substrate 11 with a transparent electrode layer 20, and a quantum dot 22 formed on the oxide semiconductor layer. A method of manufacturing the quantum dot sensitization type solar battery includes the following steps of: forming the oxide semiconductor layer 21 to the substrate 11; generating the quantum dot 22 in a mixture containing a dispersant consisting of an interfacial active agent; separating the quantum dot 22 that adsorbs a polar molecule; producing fluid dispersion obtained by dispersing the separated quantum dot 22 in a low-boiling point organic solvent; and contacting the substrate 11 to which the oxide semiconductor layer 21 is formed with the fluid dispersion. |
