This paper discussed the effect of different composition ratio of Iodine doped multiwalled carbon nanotubes (I-MWCNTs) in MEH-PPV for organic solar cell applications. The I-MWCNTs compositions were varied from 0, 30, 50, 60 and 80 wt% and the effect to the electrical, optical and physical properties were investigated. The MWCNTs was doped with acceptor atoms which is Iodine, before it is being mix...
Titanium dioxide (TiO2) nanopowders of pure and niobium (Nb) doped TiO2 were synthesized using a sol gel immersed heater method. The nanopowders were then used as a filler in poly [2-methoxy-5-(2'-ethylhexyloxy)-p-phneylene] (MEH-PPV) to form hybrid organic-inorganic solar cells. In this study, the influence of TiO2 doped with different concentrations of niobium on the properties of nanohybrid MEH-PPV:...
Nb-doped TiO2 thin films have been successfully prepared using liquid phase solution method. For the first time, Nb-doped sol-gel has been combined with commercially available TiO2 nanopowder (Degussa P25) for preparing Nb-doped TiO2 photoanode for DSSC application. EDX analysis confirms the presence of Nb in the thin films. Nb-doped TiO2 sample showed improvement in term of electrical resistivity...
Amorphous carbon (a-C) thin films was deposited using Aerosol-Assisted CVD (AACVD) method and the properties was discussed. Flow rate of the experimental setup was varied (15, 30, 45 and 60 bubbles per minute) in order to optimize the a-C thin film characteristics and the electrical, optical and structural properties were investigated. The electrical properties was characterized by current-voltage...
In this paper, we report the electrical conductivity of nanocomposited MEH-PPV:I-MWNT thin film by varying the composition of Iodine doped multi-walled nanotubes (I-MWNT) in MEH-PPV matrix from 0, 2 and 4 wt%. Electrical conductivity showed increasing in value as the composition of I-MWNT increased from 0, 2 to 4 wt%. The value of conductivity is very outstanding when the polymer was blended with...
Aligned Aluminum (Al)-doped zinc oxide (ZnO) nanorod arrays were prepared on seeded catalyst-coated glass substrates using a novel technique of sonicated sol-gel immersion method at different annealing temperatures. The diameter sizes of synthesized hexagonal-shaped nanorods are found to be in the range between 50 nm to 150 nm. The annealing treatment up to 500 °C did not give any significance effects...
Nitrogen-doped amorphous carbon thin films have been prepared by thermal chemical vapor deposition (CVD) technique at different temperature. The preparation involved argon, camphor and nitrogen as carrier gas, carbon source and dopant respectively. The effects of nitrogen incorporation in the amorphous carbon thin film on electrical and optical properties was characterized by using Advantest R6243...
Titanium Dioxide (TiO2) thin films have been successfully deposited on glass substrate using sol-gel method. The samples were then annealed in a furnace under different oxygen gas flow rate. Current-Voltage (I-V) measurement, SEM, and UV-Vis characterization are done for all samples. SEM images confirm the nanostructured nature of the thin films. The sample with higher oxygen flow rate shows significant...
Amorphous carbon thin films have been grown on quartz substrates by an economical and simple technique, thermal CVD system with methane as starting material. Since, the decomposition of methane required high thermal energy, thus the deposition temperatures were varied from 700-1000°C. The formation of a-C thin films and its properties were characterized using UV-Vis Spectrophotometer and Advantest...
Amorphous carbon (a-C) thin films deposited with thermal CVD, have been characterized by a standard two-probe method using Advantest R6243 DC Voltage Current Source/Monitor and SemiPro Curve Software and Raman scattering experiment at an excitation wavelength of 514.5 nm provided by HORIBA Jobin Yvon (HR800) Raman. The films were prepared at various deposition temperatures ranging from 650-900°C....
Zinc Oxide (ZnO) nanofibers have received broad attention for their wide high technological applications such as for nanosensors, thin film transistors and optoelectronic devices. In this paper, a novel ZnO nanofibers synthesis method using gas blocker in thermal CVD was introduced. ZnO nanofibers with diameter varies from approximately 10 to 50 nm were successfully synthesized. The structural properties...
