Abstract
The time dependence of the current response induced by a chopped laser beam was measured for dye-doped vinylidene fluoride/trifluoroethylene copolymers spin coated on an ITO coated glass substrate. In addition to conventional pyroelectric response, an anomalous current was observed in the high dye concentration region. This effect was explained by the photoconductivity of dye molecules densely dispersed in the noncrystalline regions of the polymer matrix
