▎ 摘　　要

NOVELTY - The method involves preparing titanium dioxide colloid that is coated on a conductive glass substrate. A titanium dioxide film is prepared. A quantum dot sensitized titanium dioxide photo-anode is coated on long after-glow material. Isopropanol chloroplatinic acid solution is prepared. A platinum counter electrode is prepared by pyrolysis and arranged on the conductive glass substrate. A quantum dot is formed on the long afterglow material. Liquid electrolyte is added for assembling a middle-hole-sensitized solar cell light anode on a sensitized platinum counter electrode. USE - Method for preparing a graphene-based quantum dot-mesoporous-sensitized solar battery. ADVANTAGE - The method enables simplifying graphene-based quantum dot-mesoporous-sensitized solar battery manufacturing process with stable performance, low manufacturing cost, all-weather mesoporous sensitized solar cell large space and high photoelectric conversion efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-based quantum dot-mesoporous-sensitized solar battery. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a relationship between characteristics of a graphene-based quantum dot-mesoporous-sensitized solar battery.
