摘 要:A systematic study of the charge transport and electrical properties in poly(3-hexylthiophene) (P3HT) polymer layers is *** demonstrate that the temperature-dependent current-voltage J (V,T) characteristics of hole-only devices based on P3HT can be accurately described using the recently introduced extended Gaussian disorder model (EGDM).A particular numerical method adopting the uneven discretization and Newton iteration method is used to solve the coupled equations describing the space-charge limited (SCL) current in conjugated *** the polymer studied,we find the width of the density of states σ =0.1 eV and the lattice constant a =*** on the numerical method and EGDM,we further calculate and analyze some important electrical properties for P3HT in detail,including the variation of current-voltage characteristics with the boundary carrier density and the distribution of charge-carrier density and electric field with the distance from interface.
