In this study, an ideal planar perovskite solar cell (PSC) has been proposed and simulated by using Tungsten Disulfide (WS2) as electron transport layer (ETL). Effects of various amphoteric defect states PSC based on CH3NH3PbI3−xXx absorber the interface properties both ETL hole (HTL) are quantitatively analysed SCAPS-1D numerical simulator. Results show that device performance is highly influenced defects in rather than (IDL). It also revealed quantitative tolerable range IDLs less 1015...
Abstract Radio frequency (RF) magnetron sputtering was used to deposit tungsten disulfide (WS 2 ) thin films on top of soda lime glass substrates. The deposition power RF varied at 50, 100, 150, 200, and 250 W investigate the impact film characteristics determine optimized conditions for suitable application in thin-film solar cells. Morphological, structural, opto-electronic properties as-grown were investigated analyzed different powers. All WS exhibited granular morphology consisted a...
In this study, nickel oxide (NiO) thin films were deposited on soda lime glass using radio-frequency magnetron sputtering at different growth (substrate) temperatures ranging from room temperature (RT) to 400 °C. The effects of substrate the structural, morphological, electrical, and optical properties investigated. XRD pattern unveiled a dominant peak with (2 0 0) preferential orientations for film grown 100 However, samples high temperatures, gradual decrease intensity was observed, which...
Controlling the defect in perovskite absorber layer is a very crucial issue for developing highly efficient and stable solar cells (PSCs) as it exhibits existence of unavoidable defects even after careful fabrication process. In this study, presence has been evaluated through analysis its structural optical properties. Then investigations on impact density associated cell parameters have carried out by numerical simulation utilizing SCAPS-1D software. Besides density, thickness also varied...
ABSTRACT This article describes the adsorption and tensile behavior of electrospun polyacrylonitrile (PAN) nanofiber mats loaded with different amounts ZnO [0.5, 1.0, 2.0, 5.0 wt%] nanoparticles. X‐ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transforminfrared (FTIR) spectroscopy, thermal gravimetric analysis (TGA) were utilized to characterize resulting composite nanofibers. Microscopic investigations revealed that increase in surface roughness diameter PAN nanofibers...
Bilayer nanofiber membranes with enhanced adsorption and mechanical properties were produced by combining a layer of polyacrylonitrile (PAN) functionalized metal oxides (MO) ZnO or TiO2 chitosan (CS) via consecutive electrospinning. The the bilayer PAN/MO–CS against lead (Pb(II)) cadmium (Cd(II)) ions investigated, including effects solution pH, initial ion concentrations, interaction time. integration CS into PAN/MO nanofibers increased capacity 102% 405%, compared to single layer....
Abstract Quantum dots (QDs) are semiconducting inorganic nanoparticles, tiny molecules of 2–10 nm sizes to strength the quantum confinements electrons. The QDs good enough emit light onto electrons for exciting and returning ground state. Here, CdSe/ZnS core/shell have been prepared applied electrochemical sensor development in this approach. Flat glassy carbon electrode (GCE) was coated with as very thin uniform layer result selective efficient 3-CP (3-chlorophenol). significant analytical...
Abstract The interface between the electron transport layer (ETL) and perovskite is essential for fabricating efficient stable solar cells (PSCs). In this study, we introduced a bilayer ETL of W-doped ZnO single crystalline anatase TiO2 nanoparticles (average diameter = 6-10 nm) to mitigate degradation MA-containing layer. After 12 hours annealing at 85°C, grown on exhibited strong peaks, indicating significant slowdown in decomposition. Moreover, device demonstrated superior thermal...
