Abstract |
|
|
| The opto-electronic properties of copper sulphide can be tuned by the controlled incorporation of selenium. In this paper we report the growth of Copper Sulpho Selenide (CuSSe) using a hybrid process involving the Chemical Bath Deposition (CBD) of CuS and Electrodeposition (ED) of selenium precursors on CuS. The incorporation of selenium affects the structural, optical and morphological properties of the resulting film, which are characterized by X-ray diffraction (XRD), UV-VIS Spectrometer and Scanning Electron Microscopy (SEM) & Atomic Force Microscopy (AFM). It is found that the incorporation of selenium resulted better crystalline structure and excellent optical properties. The SEM pictures confirm the uniform surface morphology with good distribution of crystallites. This new approach encompasses many advantages over the conventional methods in terms of reaction conditions (i.e. lower temperature), product quality, and cost. CuSSe thin film obtained by this method could be potential building blocks to construct functional devices, solar cell, etc. |
