Abstract

In this research, three copper sulfide thin films using three different copper-source precursors including: copper sulfate, copper chloride and copper acetate (M1, M2 and M3 samples, respectively) are prepared by SPRAY PYROLYSIS method at 285oC on glass substrate and their physical properties were investigated. The physical study on these three layers showed that using different copper source precursors lead to various properties not only in morphologies of the samples, but also on their structural, electrical and OPTICAL PROPERTIES. From structural study (XRD) we found that M1 and M2 samples are crystalline in covellite phase with preferred direction of (200) and (102), respectively, but M3 has an amorphous structure. Also from OPTICAL PROPERTIES point of view it is found that all samples have a relatively high absorbance ( ~ 105 cm-1). ELECTRICAL PROPERTIES study showed all samples have p-type conductivity and among these samples M3 has the highest hole concentration (about 1×1019 cm-3). Due to exclusive properties of the sample prepared by copper acetate precursor, i.e. M3, in continue we have investigated the spray rate effect on physical properties of this sample. It was revealed that with decreasing the spray rate the OPTICAL PROPERTIES of the layers are improved and this could be useful in transmitting solar light control device applications.
