Conjugated polymer blends operation

In this section we review theoretical and experimental results important for understanding the photophysics of polymer solar cells. We examine the states that are involved in the processes of photoinduced charge generation, and present a theoretical framework that describes the separation and recombination of charge-transfer states. Finally, we review the mechanisms for charge formation that operate in a fdm of a single conjugated polymer and the additional mechanisms, relevant to solar cell devices, that occur in binary donor acceptor blends.
