Use of rylene derivatives I with the following definition of the variables: X together both -COOM; Y a radical -L-NR1R2(y1) -L-Z-R3(y2) the other radical hydrogen; together both hydrogen; R is optionally substituted (het)aryloxy, (het)arylthio; P is -NR1R2; B is alkylene; optionally substituted phenylene; combinations thereof; A is -COOM; -SO3M; -PO3M2; D is optionally substituted phenylene, naphthylene, pyridylene; M is hydrogen; alkali metal cation; [NR5]4+; L is a chemical bond; optionally indirectly bonded, optionally substituted (het)arylene radical; R1, R2 are optionally substituted (cyclo)alkyl, (het)aryl; together optionally substituted ring comprising the nitrogen atom; Z is -O-; -S-; R3 is optionally substituted alkyl, (het)aryl; R' is hydrogen; optionally substituted (cyclo)alkyl, (het)aryl; R5 is hydrogen; optionally substituted alkyl (het)aryl; m is 0, 1, 2; n, p m=0: 0, 2, 4 where: n+p=2, 4, if appropriate 0; m=1: 0, 2, 4 where: n+p=0, 2, 4; m=2: 0, 4, 6 where: n+p=0, 4, 6, or of mixtures thereof as photosensitizers in solar cells.
