ABSTRACT
Binh et al. (1992) measured photogeneration efficiencies of poly(3-dodecylthiophene). The field and temperature dependencies agreed with one-dimensional Onsager models due to Haberkorn and Michel-Beyerle (1973) and Seiferheld et al. (1983). In one-dimensional models of the Onsager formalism, the photogeneration efficiency does not saturate with decreasing field, as predicted for three dimensional arguments. The thermalization distance was between 40 and 50 A, considerably larger than values for polymers derived from three-dimensional Onsager models. The spectral dependence of the photogeneration efficiency was described by an argument based on the dissociation of a Frenkel exciton.
