POLYMERS COMPRISING 3 -SUBSTITUTED THIOPHENE MOIETIES AS ACTIVE LAYERS FOR SOLAR CELLS

The invention relates to new monomers and polymers as well as blends of such polymers with an electron acceptor. The invention also relates to a blend for use in a photovoltaic device, comprising: (a) a polymer comprising monomer units according to the formula (I), wherein L' is selected from the group consisting of L-C(O)O-J, L-C(O)NR'-J, L-OCO-J', L-NR'CO-J', L-SCO-J', L-O-J, L-S-J, L-Se-J, L-NR'-J and L-CN wherein L is a linear or branched alkylene group having from 1 to 10 carbon atoms, wherein J is a hydrogen atom or a linear or branched alkyl group having from 1 to 4 carbon atoms, wherein J' is a group having from 1 to 10 carbon atoms, being saturated or unsaturated, linear or branched, comprising a phenyl unit or not comprising a phenyl unit, wherein R' is a hydrogen atom or a linear or branched alkyl group having from 1 to 4 carbon atoms, and (b) an electron acceptor such as a fullerene derivative.
