Modification of Donor/Acceptor Interface for Efficient Charge Transfer in Organic Solar Cells
Organic Solar Cells (OSCs) have various advantages such as low fabrication cost, lightweight, and high flexibility, compared with inorganic solar cells. Poly(3-hexylthiophene) (P3HT) is the most studied conjugated polymers as an electron donor, and 6,6-phenyl-C61 butyric acid methyl ester (PCBM) is known as an excellent acceptor.1 The concept of bulk heterojunction (BHJ), I.e. A simple mixture of a donor and an acceptor in the films, was a major breakthrough for the improvement of the performance. Although relatively high performances have been reported, there is almost no information about the molecular structures at the interface of the donor and the acceptor in BHJ. Because important photophysical processes of OSCs such as charge transfer and recombination occur only at the interfaces, the understanding and the control of theinterfacial structuresare very important to improve the efficiency of OSCs.
