Influence of post-deposition annealing on structural, optical and transport properties of nanocomposite ZnO-Ag thin films

Fabrication and characterization of ZnO/Si Heterojunction by Laser Ablation for Solar Cell Application

“…I-V characteristics of the solar cell under forward and reveres bias at room temperature under darkness were explained in figure (8) and with illumination of 41 µW/cm 2 in figure (9). It is clear from figures (8,9) that the current value with illumination was higher than that in darkness for the same voltage, because of electron-hole generation due to light absorption [20,25]. Which indicate the effective generation of electron-hole in the junction by incident photon?…”

“…The reveres (I-V) characteristics of the heterojunction measured under dark and illumination of (41µW/cm 2 ) tungsten lamb. Figures (8,9, and 10) illustrate the I-V characteristics.…”

“…ZnO thin films one the most intensive material that has demonstrated significant interest in modern industry [5][6][7]. Several studies have been done in the last few years about their potential applications in transparent electrode display, windows layers in solar cells, ultraviolet laser emission photo detectors, light emitting diodes, laser diodes, gas sensing, and bio sensor [8][9][10][11]. Since the morphology of the synthesized nanoparticles depend on the preparation of nanoparticles method, therefore it is important to get optimum conditions for synthesizing ZnO nanoparticles and controlling on the crystals morphology such as size, shape and various parameters that effect on the ZnO properties.…”

Two-step strategy, growth mechanism and optical properties of plasmonic Ag-modified ZnO nanomaterials

“…In order to expand the potential applications and improve the application properties of ZnO, many researchers have tried to modify ZnO with different materials, such as metals 7 and semiconductors. 8 Among them, ZnO compounded with metallic nanoparticles (NPs) has received signicant attention, such as Sr/ZnO, [9][10][11] Cu/ ZnO, 12,13 Ag/ZnO, [13][14][15] Au/ZnO, 16,17 Ce/ZnO, 18,19 and so forth. Kumar et al proposed that metal-semiconductor nanocomposite lms have a wide range of promising applications in plasma and photonic elds, such as optical sensing, photoemitters, and photoelectric conversion elds.…”

“…Kumar et al proposed that metal-semiconductor nanocomposite lms have a wide range of promising applications in plasma and photonic elds, such as optical sensing, photoemitters, and photoelectric conversion elds. 14 Noble metal nanoparticle structures have attracted signicant attention owing to their unique localized surface plasmon resonance (LSPR) (i.e., oscillations of free electrons generating large electric elds on the surface of metal nanostructures under external light irradiation). For example, Zuo et al proposed that noble metal NPs can induce LSPR to activate photocatalytic hydrogen precipitation reaction (HER) and to enhance the luminescence or absorption ability of the semiconductors.…”
