Synthesis and characterization of chemically deposited flower-like CdSe0.6Te0.4 thin films for solar cell application

In present work, we have successfully deposited flower-like CdSe 0.6Te0.4 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 1.61 eV and water contact angle of CdSe 0.6Te0.4 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
