Electrical and Physical Properties of Nanocomposited MEH-PPV: CNTs for Organic Solar Cells Application

Abstract

This paper discussed the physical and electrical properties of annealed and non-annealed CNTs in nanocomposited MEH-PPV:CNTs. By comparing these two types of CNTs, it is proven that annealed CNTs showed improvement in both properties compared to the non-annealed CNTs. The main improvement related to the physical properties from one aspect, influence the electrical of the nanocomposited MEH-PPV:CNTs thin film. The non-annealed CNTs with diameter size 8-9 nm is lessen to 5-6 nm after annealing. The photo conductivity increased from 11.2 x 10-3 S/m to 22.9 x 10-3 S/m.
