A photovoltaic device and a method for production thereof. The photovoltaic device comprises an anode ( 32 ), a cathode ( 46 ) spaced apart from the anode, and at least one subcell disposed between the anode and the cathode. The subcell comprises a charge-transfer dyad ( 38 ) with a light absorbing electron donor moiety ( 40 ) and an electron acceptor moiety ( 42 ), which are covalently linked to each other in a non-flexible configuration and oriented such that each subcell is capable of performing primary photo-induced vectorial electron transfer between the donor and acceptor moieties in the direction from the anode to cathode. The structure of the donor-acceptor molecule is highly symmetric, which greatly increases the intramolecular electron transfer probability and, thereby, the efficiency of the device.
