Abstract
In present work, we have successfully deposited flower-like CdSe0.6Te0.4 thin films onto glass and FTO coated glass substrates by facile chemical bath deposition (CBD) method. The X-ray diffraction study revealed that the films are polycrystalline in nature exhibiting hexagonal crystal structure. FESEM analysis showed the formation of 3D flowerlike CdSe0.6Te0.4 nanostructures composed of number of flake-like thin nanopetals. Moreover, the optical absorption study revealed the band gap energy of 1.61eV and water contact angle of CdSe0.6Te0.4 thin film lies in the hydrophilic regime which enhances the intimate contact at electrode/electrolyte interface. The photo-conversion efficiency and fill factor of this photo-electrochemical cell are found to be 0.43% and 0.58, respectively.
