Optoelectronic component comprises an electrode (2), a counter electrode (6), and at least one organic light-sensitive layer (4) between the electrode and the counter electrode, which comprises an electron withdrawing-extended donor block-electron withdrawing compound as a main component. The extended donor block has maximum of 9 conjugated double bonds in linear sequence, made of heterocyclic 5 rings, systems of same or mixed type annelated from it and/or vinylene. The donor block has at least one substituent.
