A terrylene compound of formula I:
wherein R
1
to R
4
are each independently an unsubstituted or substituted alkyl, aryl, thiophenyl or oligothiophenyl group, or a hydrogen atom. Two adjacent radicals selected from R
1
to R
4
, together with the carbon atoms of the benzene ring to which they are bonded, may also form a fused ring system having 1 to 8 additional rings. With the carbon atoms to which it is bonded, A forms a fused monocyclic, dicyclic, tricyclic, tetracyclic, pentacyclic or hexacyclic ring system which optionally contains one or more independently selected substituents. A process for preparing the terrylene compound. An organic solar cell with a photoactive region including at least one organic donor material in contact with at least one organic acceptor material, the donor material and the acceptor material forming a donor-acceptor heterojunction, and the photoactive region including at least one such terrylene compound.
