Evaporation Method

This research aims to grow a thin film Sn(Se0.2S0.8) by evaporation method. The researcher can understand the effect of spacer variations towards the crystal structure, lattice parameter, surface morphology, and chemical composition of Sn(Se0,2S0,8) thin film. The process of Sn(Se0.2S0.8) thin film preparation was done by using the evaporation method with pressure about 2 x 10-5 mbar. The process of Sn(Se0.2S0.8) thin film deposition was performed by giving some space between the substrate and the source i.e. 25 cm, 15 cm, and 10 cm. Characterization process was performed by using X-ray Diffraction (XRD) to determine the structure and parameter of thin film, Scanning Electron Microscopy  (SEM) to determine the thin film of surface morphology, and Energy Dispersive Analysis X-Ray (EDAX)  to determine the chemical composition of the thin film. The result of XRD characterization show that the Sn(Se0.2S0.8) thin film was  polycrystalline and it has an orthorombic crystal structure, with the lattice parameter  were sample 1 (spacer 25 cm): a = 4.306 Å, b = 11.30 Å, c = 4.139 Å; sample 2 (spacer 15 cm): a = 4.286 Å, b = 11.18 Å, c = 4.123 Å; sample 3 (spacer 10 cm): a = 4.301 Å, b = 11.30 Å, c = 4.143 Å. The result of SEM characterization in the sample 2 of Sn(Se0.2S0.8) showed that the surface morphology of the sample consisted of homogeneous oval shaped grains, with the diameter size of crystal grains on the surface about 0.3 μm – 0.5 μm. The result of EDAX analysis showed that comparison of percentage of chemical composition thin film Sn(Se0.2S0.8) was 1 : 0.11 : 0.79. Keywords: evaporation method, semiconductor Sn(Se0.2S0.8), solar cell, material characteristics

Electrochemical deposition and characterization of nanocrystallite-CdS thin films for thin film solar cell application are reported. The two-electrode system used provides a relatively simple and cost-effective approach for large-scale deposition of semiconductors for solar cell and other optoelectronic device application. Five CdS thin films were deposited for 45 minutes each at different cathodic deposition voltages in order to study their properties. X-ray diffraction study reveals that the as-deposited films contain mixed phases of hexagonal and cubic CdS crystallites with large amounts of internal strain and dislocation density. Postdeposition annealing results in phase transformation which leaves the films with only the hexagonal crystal phase and reduced strain and dislocation density while increasing the crystallite sizes from 21.0–42.0 nm to 31.2–63.0 nm. Photoelectrochemical cell study shows that all the CdS films have n-type electrical conductivity. Optical characterization reveals that all samples show similar transmittance and absorbance responses with the transmittance slightly increasing towards higher growth voltages. All the annealed films show energy bandgap of 2.42 eV. Scanning electron microscopy and energy dispersive X-ray analyses show that grains on the surface of the films tend to get cemented together after annealing with prior CdCl2 treatment while all the films are S-rich.

In the present report, the synthesis process of CuInxGa1-xSe2 nanoparticles as an absorption layer in tetraethylene glycol using metallic chloride and Se powder for the purpose of solar cell application. Whole processes were performed under glovebox condition. Nanoparticles sizes were achieved via manipulation of reaction temperature and various precursor concentrations. CuInxGa1-xSe2 or CIGS nanoparticles with diameters in the range of about 20-50 nm were prepared via polyol route and purified through centrifugation and precipitation processes. Then nanoparticles were dispersed to obtain stable inks that could be directly used for thin-film deposition via spin coating. Then, CIGS nanoparticles were coated on soda lime glass for fabrication of inorganic thin film solar cell via spin coating as a film. In those devices, the prepared films yielded relatively dense CuInGaSe2 films with some void spaces. For elimination of the void spaces, the nanocrystals were exposed to selenium vapor atmosphere. Filling the voids with selenium can lead to the fabrication of CIGS absorptive layers having good dense structures and high efficiency. CIGS thin films were characterized by various analytical tools, such as XRD, UV-Visible spectroscopy and SEM imaging.

AbstractWe apply variational autoencoders (VAE) to X-ray diffraction (XRD) data analysis on both simulated and experimental thin-film data. We show that crystal structure representations learned by a VAE reveal latent information, such as the structural similarity of textured diffraction patterns. While other artificial intelligence (AI) agents are effective at classifying XRD data into known phases, a similarly conditioned VAE is uniquely effective at knowing what it doesn’t know: it can rapidly identify data outside the distribution it was trained on, such as novel phases and mixtures. These capabilities demonstrate that a VAE is a valuable AI agent for aiding materials discovery and understanding XRD measurements both ‘on-the-fly’ and during post hoc analysis.

Sol Gel Process

Strontium substituted hydroxyapatite(SrHAp) were fabricated both in the form of powder as reference and thin film by using inorganic precursor reaction. The sol-gel process has been used for the deposition of SrHAp layer on stainless steal 316L substrate by spin coating technique, after that the films were annealed in air at various temperatures. The chemical composition of SrHAp is represented (SrxCa1-x)5(PO4)3OH, where x is equal to 0, 0.5 and 1.0. Investigations of the phase structure of SrHAp were carried out by using X-ray diffraction technique (XRD). The results showed that strontium is incorporated into hydroxyapatite where its substitution for calcium increases in the lattice parameters, and Sr3(PO4)2 can be detected at 900°C. The SEM micrographs showed that SrHAp films exhibited porous structure before develop to a cross-linking structure.

<div style="text-align: justify;">Thin film solar cell experience fast development, especially for thin film solar cell CdTe and Cu(In,Ga)Se2 (CIGS). However, the usage of rare element in the nature such as In, Te, and Ga and toxic such as Cd give limitation in the future development and production growth in big scale. Development of other alternative compound with maintain the profit of electronic and optic character which get from CIGS chalcopyrite compound will be explain. Compound of Cu2ZnSnSe4 (CZTSe) is downward compound from CIGS with substitute the In and Ga element with Zn and Sn. The compound kesterite structure can be modified with variation of chalcogen element to get wanted character in solar cell application. Efficiency record of photovoltaic devices conversion used this compound or downward reach 9.7%.©2016 JNSMR UIN Walisongo. All rights reserved.</div>
