These changes are reflected in the model by the variation of internal parameters such as permittivity and effective mass of the hole. We used this approach to modify the model recently designed by Arkhipov, Emelianova and Baessler, describing a thermally activated escape of a hole from a quantum well in a Coulombic field of a localized electron. Our approach is particularly suitable for the description of the charge carrier photogeneration process in a polymer consisted of tenuously packed p conjugated polymer chains, as documented by its application to the experimental results of charge carrier photogeneration in poly{1-[4-(trimethylsilyl)phenyl]-2-phenylacetylene}.
