摘要： An aqueous acidic solution and an aqueous acidic etching solution suitable for texturizing the surface of single crystal and polycrystal silicon substrates, hydrofluoric acid; nitric acid; and at least one anionic polyether, which is surface active; a method for texturizing the surface of single crystal and polycrystal silicon substrates comprising the step of (1) contacting at least one major surface of a substrate with the said aqueous acidic etching solution; (2) etching the at least one major surface of the substrate for a time and at a temperature sufficient to obtain a surface texturization consisting of recesses and protrusions; and (3) removing the at least one major surface of the substrate from the contact with the aqueous acidic etching solution; and a method for manufacturing photovoltaic cells and solar cells using the said solution and the said texturizing method.

摘要： Quaternized terpolymer formed from (A) ethylene, (B) C2-C14-alkenyl esters of one or more aliphatic C1-C20-monocarboxylic acids or C1-C24-alkyl esters of acrylic acid or of methacrylic acid and (Cq) ethylenically unsaturated monomers which comprise at least one tertiary nitrogen atom which is partly or fully in quaternized form. The quaternized terpolymer is suitable as a fuel additive for reducing or preventing deposits, for reducing fuel consumption and for minimizing power loss in direct-injection diesel engines, especially in diesel engines with common-rail injection systems.
