نویسندگان
چکیده
Thin films of copper indium diselenide (CIS) were prepared by chemical bath deposition technique onto glass substrate at 60C. The studies on composition, morphology, optical absorption, electrical conductivity and structure of the films were carried out. Characterization includes X-ray diffraction (XRD), Scanning electron microscopy (SEM), Atomic force microscopy (AFM), Energy dispersive x-ray analysis (EDAX), Absorption spectroscopy. The results are discussed and interpreted.

Study of Composition and Optical Properties of Chemically Deposited Pd-xSb2S3 Thin Films
The study reports on the effects of different concentration of palladium impurities on the compositional and optical properties of Palladium Doped Antimony Sulphide (Pd-xSb2S3) thin films grown by the chemical bath deposition method. The films were grown at room temperature and other deposition conditions such as the bath temperature, pH, complexing agents were kept constant. The concentration ...
متن کاملCuIn(S,Se)(2) thin films prepared from a novel thioacetic acid-based solution and their photovoltaic application.
Low-cost and high-yield preparation of CuInSe2 films is the bottleneck for promising CuInSe2-based thin film solar cells. Here, we developed a simple, safe and cost-effective method using thioacetic acid to fabricate the absorber films of CuIn(S,Se)2 (CISSe). Dissolution of Cu2O and In(OH)3 in thioacetic acid was attributed to the strong coordination ability of S. The adhesive precursor solutio...

Crystalline tantalum thin films of about 500nm thickness were deposited on AISI 316L stainless steel substrate using magnetron sputtering. To investigate the nano-mechanical properties of tantalum films, deposition was performed at two temperatures (25°C and 200°C) on TaNx intermediate layer with different N2/Ar flow rate ratio from 0 to 30%. Nano-indentation was performed to obtain the mechani...
متن کاملStudies on sol-gel dip-coated nanostructured ZnO thin films
Nanostructured ZnO thin films were prepared by sol-gel dip coating technique. Zinc acetate and ammonium hydroxide were used as precursors and ethanol was as solvent. Ammonium hydroxide (NH4OH) solution was added drop-wise under vigorous stirring to obtain the sol-gel of different pH (varying from 6.9 to 7.2). ZnO thin films were obtained by dipping the glass substrates for few seconds and then ...

Thin films of indium doped zinc sulfide (ZnS) for different indium (In) concentrations (x=0.0 - 0.8) were deposited onto glass substrate by spray pyrolysis method at 523K temperature. Aqueous solution of zinc acetate, indium chloride and thiorea were used to deposit the In-Zn-S film. The deposited thin films were characterized by Energy dispersive X-ray (EDX), Scanning electron microscopy (SEM)...
