چکیده
This study utilized the exceptional optical and electrical properties of polypyrrole (Ppy) to fabricate high-performance optoelectronic devices. The synthesis porous-spherical Cr2O3-Cr(OH)3-Ppy/Ppy nanocomposite thin film was achieved by preparing a second Cr2O3-Cr(OH)3-Ppy on initial Ppy using K2Cr2O7 as an oxidant. nanocomposite’s were thoroughly characterized, including XRD absorbance analyses. analysis showed that crystalline size 20 nm, while demonstrated had higher in wide range compared nanomaterials, evidenced enhancement bandgap (Eg) value from 3.33 eV for 1.89 Cr2O3-Cr(OH)3-Ppy. fabricated exhibited excellent light-sensing behavior, evaluation Jph values under different light conditions various monochromatic lights with detectivity (D) 3.6 × 106 Jones (at 340 nm). device its potential solar cell, short circuit current (JSC) 13 µA open voltage (VOC) 1.91 V. Given low cost, high technical production, superior properties, it has significant use commercially available high-tech

متن کاملExchange bias in thin-film (Co/Pt)3/Cr2O3 multilayers
We have fabricated exchange-biased Co/Pt layers ((0.3 nm/1.5 nm) 3) on (0 01)-oriented Cr2O3 thin films. The multilayered films showed extremely smooth surfaces and interfaces with root mean square roughness of E0.3 nm for 10mm 10mm area. The Cr2O3 films display sufficient insulation with a relative low leakage current (1.17 10 A/cm at 380MV/m) at room temperature which allowed us to apply elec...
متن کاملPorous (001)-faceted anatase TiO2 nanorice thin film for efficient dye-sensitized solar cell
Anatase TiO2 structures with nanorice-like morphology and high exposure of (001) facet has been successfully synthesized on an ITO surface using ammonium Hexafluoro Titanate and Hexamethylenetetramine as precursor and capping agent, respectively, under a microwave-assisted liquid-phase deposition method. These anatase TiO2 nanoparticles were prepared within five minutes of reaction time by util...
