The enhancement of charge separation in optically excited TiOPc caused by nano-structural C60 thin films was studied.The C60 thin films were prepared by vacuum evaporation and electrophoretic method respectively.Nano structure of C60 with size of 200 nm was observed in the latter ones.The photovoltaic response of both types of TiOPc/C60 films was studied in the near infrared region(NIR)with monochromatic irradiation,which shows linear dependence on the pump power.The TiOPc/C60 films with nano-structural C60...
