NOVELTY - Manufacture of dye-sensitized solar cell involves preparing tetraamino manganese phthalocyanine (TAMnPc) dye; preparing titanium dioxide (TiO2) nanocrystal semiconductor thin film having a thickness of 25 mu m by silk-screen printing method; and putting TiO2 nanocrystal semiconductor thin film in dimethylformamide (DMF) solution of TAMnPc, using dye-sensitized TiO2 thin film as electrode and platinum-plated fluorinated tin oxide conducting glass as counter electrode, sealing with heat-sealing polymeric membrane, and injecting electrolyte iodine/potassium iodide/acetonitrile solution.    USE - Method for manufacturing dye-sensitized solar.    DETAILED DESCRIPTION - Manufacture of dye-sensitized solar cell involves:    (A) mixing materials comprising manganese acetate tetrahydrate, tetranitrophthalic acid and carbamide at ratio of 1:4:40 with ammonium molybdate tetrahydrate (catalyst), uniformly grinding, adding into 500 ml three-opening flask, adding nitrobenzene solution, heating flask in oil at 180-200 degrees C, simultaneously stirring, reacting for 5 hours, cooling, filtering, rinsing with methanol and filtering until there is no nitrobenzene smell, boiling obtained solid powder in hydrochloric acid (1 mol/L), filtering, boiling in sodium hydroxide (1 mol/L), filtering, washing with deionized water until mediosilicic, and drying to obtain tetranitro manganese phthalocyanine (TNMnPc); and adding TNMnPc and sodium sulfide nonahydrate at mole ratio of 1:10 into 100 ml flask, adding DMF solution and stirring, heating to 60 degrees C in oil with argon, stirring, condensing and refluxing, reacting for 5 hours, cooling, adding distilled water to reaction, repeatedly washing, filtering, and drying to obtain TAMnPc as solid product;    (B) preparing TiO2 nanocrystal semiconductor thin film having a thickness of 25 mu m by silk-screen printing method; and    (C) putting TiO2 nanocrystal semiconductor thin film in DMF solution of TAMnPc, using dye-sensitized TiO2 thin film as electrode and platinum-plated fluorinated tin oxide conducting glass as counter electrode, sealing with heat-sealing polymeric membrane, and injecting electrolyte iodine/potassium iodide/acetonitrile solution.
