rigorous parameterization of p3ht: pcbm dispersion using modified tauc-lorentz dispersion model.

A rigorous parameterization of the optical functions of p3ht: pcbm is presentedin which the imaginary part of the dielectric functione is determined by multiplying the taucjoint density of states by the obtained 2  from the lorentz oscillator model. the real part ofthe dielectric function 1 is obtained from 2  using kramers–kronig integral relations. theparameters of this model are fit to n and k data for p3ht: pcbm experimental data.
