The purpose of our paper is to simulate and optimize the electro-optical characteristics a reversed Perovskite planar solar cell. Firstly, synthesis CH3NH3PbI3 was exposed. Then, absorption, reflection transmission phenomena were studied. effects thicknesses CH3NH3PbI (d) HTL (D) layers on efficiency presented have been simulated. Subsequently, back contact metals effect Jsc, Voc, FF η taken into account. For thickness d=0.6µm, output parameters reached Voc=1.07V, Jsc=22.75mA/cm2 , FF=78%...
Abstract The sub-ppm ozone (O 3 ) sensitivity of pure cuprous (Cu 2 O) thin films based sensors have been investigated by utilizing conductivity measurements at different temperatures varies from 150 to 200 °C. structural and morphological properties Cu O sensitive layers the scanning electron microscope (SEM) x-ray diffraction (XRD) respectively. detection strongly altered electrode geometries layer thickness. sensors’ responses investigations revealed that has improved with increase in...
This work reports the manufacture and characterization of α-Fe2O3 thin thick films grown on glass substrates at 350°C using chemical spray technique subsequently modified by thermal annealing 450°C. The Crystalline structure, surface morphology optical properties were investigated. decreases film thickness affect all physical improving optical, structural mostly ethanol sensing wherein we note an improvement response from 4 under 5000 ppm for layer to 13 only 100 layer.We also this layer,...
In this work, we studied and simulated a GaAsNSb structure on Si substrate. Moreover, applied the anticrossing model conduction valence bands (VBAC). We considered antimony (Sb) nitrogen (N) concentration effect strain, band gap energy electrical characteristics. Then determined efficiency η of solar cell GaAsNSb/Si. The Sb N concentrations is taken into account. For = 12% 1% an around 27% obtained. This investigation allowed us to optimize in order create high reliable cell. Our results can...
