the doping sensitization can be considered to be D/A sensitization, which causes
dopant ionization.
This model predicts that the ionization rate of blended films can be further
increased by increasing the H 2 Pc ratio. In fact, the ionization rate (Fig. 9.10e)
increases proportionally to the H 2 Pc ratio and approached 97% at 99:1 (H 2 Pc:C 60 ).
