Abstract
Electric properties and photovoltaic effects in vacuum were investigated on the evaporated Ⅲb metal phthalocyanine thin films. The Ⅲb metals have been used such as Aluminum, Gallium and Indium, The dark-conductivity and photo-conductivity up to the middle electric field show the ohmic conduction after the correction with the value of photovoltages. The activation energies calculated from the plot of Log lp vs. 1/T are between 0.06 and 0.1 eV. The photovoltages of AlClPc, GaClPc and InClPc under Xenon lamp are 364.279 and 154 mV, respectively.
When the incident irradiation was directed through the transparent NESA electrode, photovoltaic action spectrum of GaClPc matches the absorption spectrum, and spectral peakes of InClPc correspond to the absorption bottom, GaClPc and InClPc are estimated to be p-type and n-type semiconductors, respectively.
