Charge separation and recombination in organic solar cells — •James Durrant — Imperial College London

My lecture will focus on charge separation and recombination in polymer / fullerene solar cells. The talk will be based around transient optical and optoelectronic studies of yields and lifetimes of charge carriers in blend films and solar cells. Comparative studies will be presented of different materials systems, including over 20 different polymers. On the basis of these data, I will address the parameters which influencing charge separation and recombination, including the roles of interfacial energetics, interface structure and blend nanomorphology and macroscopic electric fields and how these processes impact upon device performance.
