Photoelectric Effect in Single and Double Layers of Metal-Free and Lead Phthalocyanines Evapolated films
Photoelectric properties of evapolated metal-free phthalocyanine (H 2 Pc) and lead phthalocyanine (PbPc) films were investigated in the sandwich type cells using three kinds of metal electrodes (Au, Al, Pb). Current-voltage (I-V) characteristics and short circuit photo current (I sc ) spectra strong...
