Organic semiconductor have been discovered in different application devices such as organic light emitting diodes (OLEDs). Poly [2-methoxy-5(2′-ethylhexyloxy)-1, 4-phenylenevinylene], MEH-PPV widely used in this device because its ability to produce a good optical quality films. The MEH-PPV was prepared on glass substrate by spin coating method. The thin film was investigated with different concentration...
The effect of Iodine flow rate in nanocomposited MEH-PPV:I-MWCNT was investigated by means of electrical, optical and physical characterization. First, 120 mg of MWCNT was doped with 1g of Iodine using thermal chemical vapour deposition method (TCVD). The doping process was done for 1 hour with Iodine flow rate varied from 0.1, 0.3, 0.5, 0.7 and 0.9 l/min. On the other hand, 40 mg of MEH-PPV was stirred...
Vertically aligned Al:ZnO nanorod arrays has been used as window layer in the fabrication of ordered bulk heterojuction hybrid solar cells. The utilization of the nanorod arrays will enhance the electron transport in vertical direction and also for light harvesting applications for high performance devices. The performance of this hybrid polymer/metal oxide photovoltaic devices based on MEH-PPV [poly(2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene)]...
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:...
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...
Our work focuses on nanocomposited poly [2-methoxy, 5-(2′-ethyl-hexyloxy)-phenylenevinylene] (MEH-PPV) blend with carbon nanotube (CNTs) and titanium dioxide (TiO2). The conductivity under illumination of the nanocomposited MEH-PPV:CNTs:TiO2 thin film was investigated with the thickness increased. The conductivity showed decrement in value from 6.7 × 10−6 to 0.6 × 10−6 S/m as the thickness increased...
Our work focused on nanocomposite MEH-PPV: CNTs prepared by spin coating technique. The MEH-PPV which is in powder form (commercially available) was weighted and then dissolved in Toluene and stirred for 48 hours. Then, a small amount of CNTs were added to the MEH-PPV solution. It is sonicated for 1 hour to ensure that CNTs is well dispersed in the MEH-PPV solution. The addition of CNTs in the MEH-PPV...
