Structural and optical properties of nanocrystalline CdSe and Al:CdSe thin films for photoelectrochemical application

► The CdSe and Al:CdSe thin films have been successfully deposited by SPT. ► Hexagonal cubic structured CdSe and Al: CdSe thin films are observed. ► Large number of fine grains, Uniform and compact growth morphology. ► Hydrophilic surface nature. ► Al:CdSe have better PEC performance than CdSe.
