“…The electrical and optical properties make it extremely useful as window layer material for many photovoltaic solar cell modules [4][5][6][7]. Furthermore CdS has remained a focus of the material science community due to its important band gap, conversion efficiency, high absorption coefficient, stability and last but not the least its significantly low cost [8].…”

“…It has also been a subject of intensive research not only because of its useful band gap but also high absorption coefficient, conversion efficiency, stability, and low cost [3]. CdS thin films are a desirable and the most commonly used window materials for high-efficiency polycrystalline thin-film photovoltaic devices [4,5].…”

Thermal decomposition of suitable coordination compounds may be used as efficient route for fabrication of semiconducting layers. A new potential CdS precursor-a cadmium complex with all-sulfur Cd-coordination sphere [Cd{l-SSi(OBu t ) 3 }(S 2 CNC 4 H 8 )] 2 1-has been prepared, and its properties are investigated. The complex was obtained in the reaction between dimeric bis(tri-tert-butoxysilanethiolato)cadmium(II) [Cd{SSi(OBu t ) 3 } 2 ] 2 and ammonium N,Ntetrametylene-dithiocarbamate and characterized by spectral methods (IR, UV-Vis, MS, and NMR). X-ray structure analysis revealed the complex as molecular and dimeric in solid state with each of chelating dithiocarbamate ligands bonded to one Cd center and sulfur atoms from two tri-tertbutoxysilanethiolato ligands bridging metallic centers and thus completing the CdS 4 coordination sphere. Thin film of the precursor prepared on SiO 2 substrates via spin-coating technique was analyzed by AFM. Its decomposition was studied by thermal analysis methods (TG, DSC, and TG-FTIR). After melting at 227°C, [Cd{l-SSi(OBu t ) 3 } (S 2 CNC 4 H 8 )] 2 undergoes endothermic decomposition leading to CdS as the only solid product further identified by XRD, EDS, FIR as hexagonal CdS form. Its morphology is characteristic and may be described as ''micro-noodles''.

“…CdS, belongs to II-VI compound family, has a great application potential such as solar cells, optical detectors and optoelectronic devices [1][2][3] . It is a very desirable window layer for many photovoltaic solar cells because of its optical and electrical properties [4][5][6][7] . CdS has been the subject of intensive research because of its band gap, high absorption coefficient, reasonable conversion efficiency, stability and low cost [8] .…”

A suitable deposition method of CdS is necessary for the high performance CIGS(Cu(In0.7Ga0.3)Se2.2) solar cells. In this paper, CdS films were deposited onto glass substrates at the substrate temperture of 50°C、100°C、150°C by thermal evaporation, the effect of the temperature were presented. CdS film deposited at substrate temperture of 150°C was annealed at 150°C for 30min. All films were characterized for their morphology, structure and optical property using scanning electron microscope(SEM), X-ray diffractometer(XRD) and UV–VIS–IR transmittance respectively.The quantum efficiency of the fabricated solar cells with annealed CdS buffer layer was also enhanced at short wavelength. This new method leads to the improved performance of CIGS solar cells and also simplify the whole fabrication technology.
