NOVELTY - Preparation of a solar cell packaging glass comprises processing the glass in 0.5-2 wt.% hydrofluoric acid solution at 10-45 degrees C for 0.5-2 minutes; processing the glass in a corrosive liquid at 10-40 degrees C for 1-6 minutes to obtain a corrosion resistant glass, where the corrosive liquid is obtained by dissolving (g/L) hydrofluoric acid (60-460), ammonium fluoride (50-220), and sorbitol (250-850) in water; and coating with a coating film comprising (pts.wt.) a silane compound (0.01-7), alkaline matter (0.01-5), and water (0-9.8).    USE - Method for the preparation of a solar cell packaging glass (claimed).    ADVANTAGE - The packaging glass has increased light transmittance and reduced reflectivity, and can increase the power and the power retention rate of the solar cell.    DETAILED DESCRIPTION - Preparation of a solar cell packaging glass comprises:    (A) processing the glass in 0.5-2 wt.% hydrofluoric acid solution at 10-45 degrees C for 0.5-2 minutes;    (B) processing the glass in a corrosive liquid at 10-40 degrees C for 1-6 minutes to obtain a corrosion resistant glass, where the corrosive liquid is obtained by dissolving (g/L) hydrofluoric acid (60-460), ammonium fluoride (50-220), and sorbitol (250-850) in water; and    (C) coating with a coating film comprising (pts.wt.) compound of formula Si(R)n(X)4-n (I) (0.01-7), alkaline matter (0.01-5), and water (0-9.8).    R=H, 1-24C alkane, aryl (including optionally substituted carboatomic ring or heterocycle group containing a 5-membered ring, 6-membered ring, or 10-membered ring connected to Si through a covalent bond or 1-8C linear-chain or branch-chain alkyl), amino-alkyl (including 1-18C fatty group, or 1-18C aromatic group containing a primary amine or secondary amine group), epoxy, 1-18C cyan-alkyl, 1-18C dithiocyano-alkyl or isocyanate-alkyl, or 1-18C sulfenyl-alkyl or fluorinated group (including all-fluorinated 1-18C alkyl or 1-18C aryl, or the alkyl or phenyl in which H on the 1-8C from the tail end of the group are substituted);    x=halo or 1-6C alkoxy; and    n=0-2.    An INDEPENDENT CLAIM is included for a solar cell packaging glass.
