TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The silicon chip is p single crystal silicon chip, p poly-silicon chip, n single crystal silicon chip and n poly-silicon chip. The inorganic fluorescent powder is the ultra-dispersive grains of inorganic fluorescent powder. The basal body of the fluorescent powder is composed of solid and liquid of sodium aluminate of the same type of barium and yttrium and its formula is Baalphaa(Y,Gd)3betaAl2alpha+5betaO4alpha+12beta; the syngony of crystal lattice changes along with the variation of property relation between barium and yttrium; the valuing scope of alpha is that alpha is less than or equal to 1 or alpha is greater than or equal to 1; beta is less than or equal to 1 or beta is greater than or equal to 1. The synergistic light conversion film system is composed of polycarbonate film having a molecular mass m=12000 standard; where the volume concentration of fluorescent powder is 30%. Preferred Conditions: The wavelength of the first specific segment wave is 300-580 nm; the wavelength of the second specific segment wave is 530-610 nm. Moreover, when alpha is less than or equal to 1 and beta is less than or equal to 1, the lattice structure of solid liquid is loose and it belongs to monoclinic system. The quantum radiation rate of the synergistic light conversion film changes in the scope ranging from 75-96%, bigger along the optimization of the film concentration in the scope ranging from 0.1-0.5 mm; the whole reflection rate of the film to the natural daylight received by cell is 4-6%. Also, the polymerized layer is the organic polymer; the average polymerization degree is m=100-500; the molecular mass is 10000-20000 standard units. The synergistic light conversion film is formed by dissolving the polycarbonate into the solution of methyl dichloride (CH2Cl2) of 20% and then by cast soldering. Also, the synergistic light conversion film is formed by extruding it into the polyethylene film under the temperature of 190 centigrade; the concentration of inorganic fluorescent powder in the film is 18%; compositions specifically are: 62% low density polyethylene, 20% EVA, 18% fluorescent powder; besides, the concentration of the polyethylene is 10 more or less than 120, it comprises a high homogeneousness and toughness.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The synergistic light conversion film is further filled with epoxy resin. The synergistic light conversion film system is oxygenic polymer formed based on the polycarbonate or polysiloxane or polyacrylic ester; the polymer is filled with fluorescent powder with the oxide of II, III, IV elements having the frame of garnet crystal as basal body; the diameter of the grain is smaller than the peak wavelength; the content of the fluorescent powder in the polymer is 0.1-50%.
