Abstract We report on the adsorption performances of HCN, H 2 S, HF, and gases Nb Co embedded WS monolayer using density functional theory calculations. The configurations, energy, charge transfer, state, band structure, recovery time were studied to evaluate possible tailoring gas sensing properties improve sensitivity selectivity monolayer. results show that HCN exhibits better Nb-embedded with an energy −1.09 eV transfer −0.18 e, whereas S shows superior Co-embedded −1.1 0.23 e. Better...
The presence of defects, grain boundaries and other impurities in Cu2ZnSnS4 (CZTS) thin film material is detrimental on output performances fabricated solar cells. Moreover the formation non stable high resistance contacts to CZTS contribute also lower values short circuit density (Jsc), open voltage (Foc), fill factor (FF) therefore efficiency This study evaluates baseline ZnO/CdS/CZTS cell structure using AMPS-1D program quantifies reasons for limits predicted such a device. effect back...
Thin films of Copper zinc tin sulfide (Cu <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ZnSnS xmlns:xlink="http://www.w3.org/1999/xlink">4</inf> , CZTS) is one the promising semiconductor materials used in over recent years as a next generation absorber thin film solar cells thanks to its tunable direct band gap energy, large absorption coefficient, cost effective and eco-friendly nature.

ZnO thin films have been prepared by dip coating sol gel method using Taguchi technique. The underlying principle was to make something as little conceivable the measure of examination and sense best conditions for developing with great properties. We used a trial plan L9, three levels (high, medium, low) four elements (annealing temperature, precursor concentration, speed, annealing time). For each paper sol-gel arrangements were arranged, test is rehashed time. chosen carry out...
Thin films of Cadmium sulfide (CdS) is one the promising semiconductor materials which can be used as a tampon deposited by chemical bath deposition (CBD) in thin film solar cells thanks to its tunable direct band gap energy, large transmission coefficient and cost effective. The role CdS layer still debated within scientific community, but material efficiency obtained with this fine n-type very high. It could protect damage associated following spray deposits defects surface absorber or...

According to the literature, conceptual change is a primary challenge in science education. Several studies have indicated that learners use their intuitive conceptions even after instruction. Therefore, our study aimed create working conditions would support learners' achievement of change. We hypothesized integrating into teaching-learning process collaborative setting will positively impact performance reflect degree which they achieve After realization course respecting official...
