Charge Transfer Complexes of a Conjugated Polymer

摘要

The combination of the optical,mechanical,and electrophysical properties of conjugated polymers,as well as their ease of processing,recommends them for different applications,including large-area photovoltaic converters.For organic photovoltaics,efficient charge generation after excitation is of crucial importance.Such a process is exemplified by photoinduced charge transfer from a conjugated polymer,acting as a donor,to an acceptor,for example,C_(60),this process being rather efficient [1,2].In the course of photoinduced charge transfer,the exciton excited at the polymeric chain diffuses to the donor/acceptor interface and dissociates into the pair of separated charges.
