%X Multiwalled carbon nanotubes (MWCNTs) mixed in poly(3-hexylthiophene)  (P3HT) were used as a photoactive layer for organic solar cells (OSC). The  flexible OSCs of a structure of PET/rGO-P3HT/P3CT/PCBM/LiF-Al were  prepared by spincoating. The UV-Vis absorption spectra of the photoactive  films and current-voltage characteristics of the OSCs showed the advantage of  the composite devices above the pristine-polymeric ones. Under illumination  of light with a 100 mW/cm2-powerdensity, the photoelectrical conversion efficiency  (PCE) of the OSCs with 3.0 wt% MWNCTs embedded in the photoactive  layer possess a value as large as 2.35%. The obtained results suggest  further useful applications of the flexible large-area solar cells.
