Abstract

Copper phthalocyanine(CuPc) thick film solar cells were fabgricated byspin coating and their photovoltaic behavior was studied. Polyvinylidene fluoride (PVdF) was used for the binder. Aluminum and indium were employed as electrode metals to form Schottky contact to CuPc layer. The cells showed rectifying J-V characteristics in the dark and photovoltaic effect associated with white light irradiation. The photovoltaic performance of the cells strongly depended on contact metals, in which the formation of oxide layer between binder layer and electrode interface affected the solar cell. Influnce of the CuPc layer thickness, CuPc/PVdF ratio on the photovoltaic performance of the cells were also examined.
