Paper Abstract

Copper phthalocyanine (CuPc) is an important versatile organic material. It has attracted more and more attention because of its unusual stability and photoelectric properties. Copper phthalocyanine (CuPc) films, grown by vacuum sublimation, were characterized with X ray diffraction (XRD), Raman and UV-VIS spectrometry. CuPc/Aluminum (Al) Schottky solar cells were studied by varying the thickness of the CuPc layer from 30 nm to 130 nm. Optimum current density-voltage characteristics of ITO/CuPc/Al was obtained for 110 nm thick CuPc layer, which revealed the Short circuit current densities of 0.086 mA/cm2 and the Open circuit voltages of 300 mV. Bathocuproine (BCP), tris (8-hydroxyquinolato) aluminum and LiF were used respectively as buffer layer to discuss their influences on the electrical characteristics of ITO/CuPc/Al Schottky solar cells. It was found that the insertion of a thin buffer layer would improve the performance except LiF.
