The mechanism of photocarrier generation and transport in conjugated polymer is studied. After analyzing thermalization of polaronexcitons which were formed through relaxation by dissociation electronhole pairs produced by photoexcitation initially. We infer that polarons along the polymer chains recombine rapidly and polarons between chains generate photocurrent. After investigating the transport mechanism of chargecarrier in conjugated polymer, a formula of conductivity of copolymers can be derived from chargecarriers generation and transport model (see Eq(6)), the calculated values agree with experimental data very well (see Table 2). We conclude that the conductance and photoluminescence in conjugated polymer could be attributed to polaron hopping between chains.
