Abstract

The effect of additives of sensitizing Zn(II) and Co(II) complexes with 5,15-(diethoxyphosphoryl)-10,20-diphenylporphyrin on the mobility of holes in thin poly3-hexylthiophene films is studied. The charge carrier mobility is measured using the CELIV and photo-CELIV methods. It is found that the sensitizing additive does not affect the mobility of the equilibrium charge carriers, but causes a decrease in the mobility of the nonequilibrium charge carriers.
