TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Properties: The hollow silica particles have refractive index of 1.17-1.4. The antireflection film has surface resistance of 105-1012 Omega /cm. The refractive index of low refractive layer is 1.2-1.49 at 25 degrees C. Preferred Component: The antireflection film further includes a hard-coat layer formed between the substrate and the low refractive layer.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The low refractive layer composition comprises organic-inorganic hollow silica particles (in weight parts) (1-50), (meth)acrylate monomers (0.1-50), photoinitiators (0.1-5) and solvent (0.1-95) with respect to whole composition (100). Preferred Component: The fluorine compound comprises one component chosen from benzotrifluoride derivative, hexafluoro xylene derivative, trifluoromethoxy derivative, fluoroaromatic derivative, perfluorinated carboxylic acid derivative, perfluorinated carboxylic salt derivative, perfluorinated sulfonic acid derivative, perfluorinated sulfonic salt derivative, aliphatic fluorine derivative and perfluorinated fluorine derivative. EXAMPLE - An ionic compound having average particle diameter of 40 nm and solid content of 20.5%, was prepared using ionic liquid (in weight parts) (100), acetonitrile (500), potassium (30) and dichloromethane (500). Organic/inorganic hollow silica particles (A) coated with multi-functional silane compound and having refractive index of 1.35, was obtained by agitating the obtained ionic compound (10.22) and methanol (0.2) at 80 degrees C for 3 hours under nitrogen atmosphere. Component (A) (11), dipentaerythritol penta/hexaacrylate (as acrylate monomer) (5) having refractive index of 1.476, methyl isobutyl ketone (75.4), methyl ethyl ketone (7), I-184 (RTM: 1-hydroxy cyclohexyl phenyl ketone) (1), BYK- 378 (RTM: silicone denaturated oil) (0.5) and DS-1100 (RTM: perfluorinated fluoride) (0.1) were mixed, to obtain a low refractive layer composition. The obtained composition was coated on a transparent substrate having triacetyl cellulose film, and subjected to UV curing at 50 degrees C for 1 minute, to form a low refractive layer of 0.1 mu m thickness. The low refractive layer had refractive index of 1.37, excellent haze and reflectivity without degradation of light transmission. Solar cell module produced using the low refractive layer had high reliability and generation efficiency.
