摘要

The influence of the buckminsterfullerene C_(60) on photocurrent generation and hole transport properties in polymer films of poly(styrene) (PS) doped with N,N'-bis-(3-tolyl)-N,N'-diphenyl-1,1'-biphenyl-4,4'-diamine (TPD), has been determined and analyzed by using the time-of-flight technique (TOF). Measurements were realized on indium-tin oxide/polymer composites/indium-tin oxide samples. The dependence of the charge mobility as a function of the electric field and temperature was investigated and analyzed by using the Gaussian disorder model. An enhancement of photocurrent and hole mobility was observed with increasing the C_(60) concentration from 0 to 2 wt.%.
