- Abstract
With the purpose of developing organic photosensitive cells with a wide photosensitivity spectrum and improved photogeneration characteristics, an ITO/pentacene/DiMe-PTCDI/Al heterostructure formed by alternate vacuum deposition of pentacene and perylene N,N′-dimethyl-3,4,9,10-perylenetetracarboxylic diimide (DiMe-PTCDI) derivative films on the ITO substrate was studied. The effect of the heterostructure’s formation conditions on its spectral photosensitivity and photovoltaic properties was also studied. An analysis of current-voltage characteristics and frequency dependences of the impedance showed that the current through the heterojunction is controlled by thermionic emission with an ideality factor of 1.5–2.2, and the heterostructure can be simulated by an equivalent circuit consisting of two series elements representing the heterostructure bulk and space charge region.
