| Summary: | This research focused on the electrical and optical properties of nanocomposited MEH-PPV: CNTs organic solar cell thin film with different composition ratio of CNTs. The project are focusing on adding 0 wt%,l wt%, 2 wt%, 3 wt% and 4 wt% of the CNTs in order to observe the effect on it. The toluene been used as solution to dissolve the MEH-PPV and CNTs. The thin film was deposited on 2cm x 2cm glass substrate by using spin coating technique. The electrical properties characterize been done by using two point probe solar simulator to measured the current-voltage characteristic. The optical properties of the thin film were characterized using UVVIS/NIR spectrophotometer to observe the absorption and transmittance characteristic. The current-voltage was measure in two condition, which is in dark and illumination condition. The highest value of conductivity among the 5 concentration is at 4wt% concentration of CNTs with 0.02738 Sm"1 . The smaller optieal band gap among the 5 concentration was recorded at 4wt% concentration of CNTs which is at 2.00eV. |
