TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The laminated organic thin-film solar battery comprises an aluminum electrode, a C60 layer, a copper phthalocyanine layer, a titanium oxide/poly(3,4-ethylenedioxythiophene) doped with polystyrenesulfonate layer, N,N'-disubstituted-1,3,8,10-methyl quinoline acridine ketone material layer and tin oxide glass. The solar battery layers are prepared by a coating method comprising vacuum evaporation on washing of copper and tin oxide glass, respectively, evaporating N,N'-disubstituted-1,3,8,10-methyl quinoline acridone layer (10-20 nm), and C60 (2-40 nm), preparing titanium oxide/poly(3,4-ethylenedioxythiophene) doped with polystyrenesulfonate layer (50-100 nm) and titanium oxide layer (5-100 nm), by spin coating method, and vacuum evaporation of copper phthalocyanine (40-60 nm).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The N,N'-disubstituted-1,3,8,10-methyl quinoline acridine ketone compound of formula (I) is obtained by mixing 3,5-methyl amine (4-6 parts by weight), 2,5-terephthalic acid ethyl ester (4-6 parts by weight) and absolute ethyl alcohol (80-120 parts by weight), filtering the obtained product, dispersing in chloronaphthalene under argon gas, and heating at 200-300 degrees C for 2-5 hours; washing the obtained filtrate with potassium carbonate solution (8-10 parts by weight) to obtain a crude product, filtering and washing the crude product in ethanol (12-20 parts by weight), stirring in acetic acid (5-10 parts by weight), adding nitrobenzene (5-12 parts by weight), potassium hydroxide (2-8 parts by weight) and diethylene glycol (1-4 parts by weight), stirring for 6 hours at 50-100 degrees C, and purifying to obtain 1,3,8,10-methyl quinoline acridine ketone; and adding tetrahydrofuran (30-70 parts by weight), sodium hydride (4-6 parts by weight) and sodium bromide (3-15 parts by weight) to 1,3,8,10-tetramethyl quinoline acridine ketone, stirring at room temperature for 12 hours and purifying by column chromatography.R = CnH2n+1, -S(CH3)3, -Si(CH(CH3)2)3 or 2-phenylethynyl, when the alkyl bromide is methyl bromide, ethyl bromide, propyl bromide, cyclobutyl bromide, pentyl bromide, hexyl bromide, heptyl bromide, octyl bromide or nonyl bromide, R is brominated alkyl compound, phenylacetylene bromide, brominated trimethyl silane or isopropyl bromine silane; andn = 1-9.
