Metal chalcogenide hierarchical nanostructures as energy conversion devices were studied in this chapter. Cd-chalcogenide nanostructures were chosen as sample study due to their unique properties as energy converter. In the first step, different methods were introduced to grow this type of nanostructures. It was discussed three low cost-effective methods to grow the Cd-chalcogenide nanostructures such as thermal evaporation (chemical and physical vapor depositions), chemical bath deposition, and electrochemical methods. However, it was observed that samples were grown by a pulsed laser deposition method as a complex method. In addition, effects of growth conditions on morphology and optical properties of the nanostructures were investigated. In the second step, the fundamentals of solar energy conversion were described. Furthermore, quantum physics of semiconductor solar cells was studied. Finally, the Cd-chalcogenide nanostructures were introduced as solar energy conversion and important factors that can affect the efficiency of this type of solar cells were introduced.

Abstract:The structural and optical properties of the CdS, Cd 2x (CuIn) 1-x S 2 (CCIS) thin films, at x=0.2,heterojunction were studied in the present paper. The heterojunction films deposited successfully on glass slides using by the spray pyrolysis technique at 623K. The thin films CdS, CCIS and the heterojunction ITO/CdS/CCIS were characterized by using x-ray diffraction. This is to find the polycrystalline series of the CdS, and CCIS solid solution with many phases as a mixture of chalcopyrite and zinc blend. The CdS, and CCIS thin films have a grain size 35 nm, and 16 nm respectively. The surface morphology was characterized by using atomic force microscopy (AFM) technique. The optical properties of the prepared thin films were investigated by using a UV-VIS spectrophotometer in the wavelength of 300 nm to 1100 nm. The films, ITO, CdS, and CCIS show direct transition with optical energy gap (Eg) values 3.52, 2.42, and 1.7eV respectively. The optical transmission (T),absorption (A) andrefractive index (n) were also discussed . Keywords: The ITO/CdS/Cd 2x (CuIn) 1-x S 2 Structure, Optical, heterojunction and thin films..

“…Out of other thin films production techniques, CBD method is an attracting considerable attention as it does not require sophisticated instrumentation like vacuum system, high temperature system and other (531) expensive equipments. It is low cost, simple and convenient wet chemical method that has been previously used for deposition of a variety of metal chalcogenide thin films [16,19,20]. In CBD method, different substrates such as insulators, semiconductors and metals, and a large number of substrates can be coated in a single run with a proper jig design.…”

Polycrystalline manganese ditelluride (MnTe2) thin films are synthesized on commercial glass substrates by chemical bath deposition technique at different pH values (pH = 9, 10, 11 and 12). The effect of pH on the structural and optical properties of chemically deposited MnTe2 thin films have been investigated in this study. The structure and optical properties of the films are characterized by X-ray diffraction and optical absorption spectroscopy. The X-ray diffraction results suggest that the films are polycrystalline with a mixture of dominant cubic MnTe2 phase and few traces of orthorhombic MnTeO3 and MnTe2O5 phases. The optical band gap of the films increases approximately from 1.66 eV to 2.62 eV with increasing pH. Moreover, optical parameters of the films such as refractive index, extinction coefficient, real and imaginary dielectric constants are investigated using absorption and transmittance spectra taken from the UV-vis spectrophotometer. At 600 nm wavelength, refractive index and extinction coefficient values vary in the range of 1.39-1.55 and 0.17-0.23, respectively. An increase in optical band gap could be attributed to the quantum confinement effect.
