Scalability of copper selenide (CuSe) thin films using electrodeposition technique with three electrode configurations for solar energy applications

In this work, copper selenide was synthesized potentiostatically at varied voltage on conductive FTO substrate of dimension 2 by 2.4 cm² with three electrode configurations in which graphite was selected as working electrode (cathode), carbon as counter electrode (anode) and Ag/AgCl as reference electrode. In order to synthesis stoichiometric CuSe films as a good alternative window layer material with unique properties for diverse of applications, we therefore employed electrodeposition (ED) technique owing to its scalability and self- purification capability. We employed X-ray diffractometer (XRD), scanning electron microscopy (SEM), energy dispersive x-ray (EDX), x-ray fluorescence (XRF) and ultraviolet visible spectrophotometer (UV) to study the material properties and the film suitability in solar cells fabrication.
