Abstract :
In this work, pure and Bi3+, Cd2+, Na+ - doped Cu2Se thin films were prepared by chemical bath deposition (CBD) method. The effect of doping on optostructural properties was analyzed. XRD patterns show the cubic phase for pure and Bi3+, Cd2+, Na+ - doped Cu2Se thin films. The doped films show higher absorption than Cu2Se in the visible region. The band gap energies of the films were found to be 1.75 eV, 1.70 eV, 3.66 eV, 2.55 eV for pure and Bi3+, Cd2+, Na+ - doped Cu2Se thin films, respectively.
