Abstract
An organic nanocomposites, based on a conjugated polymer (MEH-PPV) as electron donor material and carbon nanopearls (CNPs) as electron acceptor material, have been elaborated and optoelectronically studied. The effect of CNPs concentration on the electric and photoelectric properties in these blends has been investigated. Dielectric measurements demonstrate that the blend conductivity displays a dramatic increase, reaching 0.6 S/m for a CNPs concentration about 1 wt.%. The elaborated organic nanocomposites were used as photoactive materials in organic solar cells.
