In this paper, we report a size-controlled metal oxide under low-temperature process for the fabrication of an electrochemical sensor based on ultra-small nickel (NiO) nanoparticles (NPs) which are utilized as electrode materials detection n-butylamine chemical. The small size effect (∼6 ± 0.5 nm) and richness Ni 3+ ion concentration as-synthesized NiO exhibited high reproducible sensitivity ∼9.51 mA·mM −1 ·cm −2 , limit (LOD) ∼144.21 μ M correlation coefficient (R) ∼ 0.9688 with improved...
In this work, a new embodiment of flexible perovskite solar cell is based on graphene (Gr) as the barrier layer and atmospheric plasma jet (APjet)-treated ZnO quantum dots (QDs) mesoscopic metal oxide ITO-PET substrates. The substrate was treated with oxygen (O2) before creating an efficient Gr, thereafter as-synthesized QDs were deposited by spin coating ITO-PET/Gr thin film. ITO-PET/Gr/ZnO-QDs film substrates finally subjected to APjet treatment using RF power ∼40 W frequency ∼13.56 MHz,...
Abstract A new and novel organic π-conjugated chromophore (named as RCNR) based on fumaronitrile-core acceptor terminal alkylated bithiophene was designed, synthesized utilized an electron-donor material for the solution-processed fabrication of bulk-heterojunction (BHJ) small molecule solar cells (SMOSCs). The exhibited a broad absorption peak near green region strong emission due to presence electron-withdrawing nature two nitrile (–CN) groups fumaronitrile acceptor. highest occupied...
A high performance perovskite solar cell was fabricated using the distinguished morphology of polyaniline nanoparticles (PANI-NPs) as an efficient hole transporting layer (HTL) with methylammonium lead iodide (CH3NH3PbI3) sensitizer. PANI-NPs were simply synthesized by oxidative chemical polymerization aniline monomer at 0-5 °C. reasonable solar-to-electricity conversion efficiency ∼6.29% a short circuit current (JSC) ∼17.97 mA/cm(2) and open voltage (VOC) ∼0.877 V accomplished...
Metal-oxide-based electrodes play a crucial role in various transparent conductive oxide (TCO) applications. Among the p-type materials, nickel is promising electrically material due to its good stability, large bandgap, and deep valence band. Here, we display pristine 3 at.%V-doped NiO synthesized by solvothermal decomposition method. The properties of both at.%V:NiO nanoparticles were characterized field emission scanning electron microscopy (FESEM), transmission (TEM), X-ray...

Hybrid organic-inorganic perovskites have been investigated for their potential to serve in next-generation perovskite solar cells (PSCs). While PSC technology is approaching commercialization, thermal and moisture stabilities remain a concern. Here, we describe the assembly of PSCs using an imidazoanthraquinone derivative (AQ) as small organic additive enhance device performance stability. Unlike polymer additives, AQ easy synthesize more economical. was synthesized because it has both...
A conversion from commercial titania (TiO2) nanoparticles to nanotubes was achieved by a hydrothermal method. The titanate nanotube (titanate) film then deposited on Si (001) substrate using an electrophoretic deposition (EPD) technique. post treatment carried out annealing the films at 300–1000°C for 30min in static air. major amount of intercalated sodium (Na) as-synthesized removed during electrodeposition process. collapse tubular structure can be seen clearly when annealed above 500°C....
