Impact of Annealing Temperature on the Morphological, Optical and Photoelectrochemical Properties of Cauliflower-like CdSe<sub>0.6</sub>Te<sub>0.4</sub> Photoelectrodes; Enhanced Solar Cell Performance
We are reporting on the impact of air annealing temperatures on the physicochemical properties of electrochemically synthesized cadmium selenium telluride (CdSe<sub>0.6</sub>Te<sub>0.4</sub>) samples for their application in a photoelectrochemical (PEC) solar cell. The CdSe&l...
