Abstract (en)
[origin: WO2012156199A1] Dispersion comprising metal oxide particles, in which a) the metal oxide particles a1) are selected from one or more oxides from the group consisting of titanium dioxide, cerium oxide, zinc oxide and zirconium dioxide, a2) are present in the dispersion with a proportion of at least 25% by weight, a3) have a mean aggregate diameter of 20 to 120 nm, and b) the liquid phase comprises b1) 90 to 99.5% by weight of one or more alkanols CnH2n+1OH where n = 2 to 4, b2) 0.5 to 10% by weight of one or more a,ß-unsaturated carboxylic acids having 4 to 12 carbon atoms, b3) 0 to 2% by weight of one or more alkanediols HO(CH2)xOH where x = 2 to 4, b4) a maximum of 5% by weight of water and b5) a maximum of 2% by weight, in total, of dispersing additives from the group consisting of polyoxyethylenated alkyl ether phosphates, polyoxyethylenated aryl ether phosphates; alkylolammonium salts of block copolymers having acidic groups; polyalkylene glycols, polyalkylene imines, polyalkylene alcohols. Use of the dispersion for production of dye solar cells.
