Bath temperature and deposition potential dependences of CuSCN nanorod arrays prepared by electrochemical deposition
Source abstract
Abstract
In this study, we report on the electrodeposition of p-type semiconductor copper thiocyanate (CuSCN) nanorods on ITO substrate from an aqueous solution. The influence of the bath temperature and deposition potential on the properties of CuSCN layers was studied. Nanorods deposited at low temperature (25 °C) exhibited better crystalline quality and orientation along the c-axis than the nanorods grown at elevated temperatures. The deposition potential turned out to influence strongly the crystallographic orientation, the morphology, as well as the optical properties of the product. Mott–Schottky measurement demonstrates that the CuSCN nanorods are p-type semiconductor, with a hole concentration (N A) eight times larger than that of the 2D thin films when the cylindrical geometry of the nanorods was taken into consideration. The CuSCN nanorods obtained in this study can be used as inexpensive inorganic hole-transporting material in solar energy application and it offers new possibilities to fabricate nanostructured solar cells in reversed process, which starts from the formation of nanostructured p-type electrode.
