Poly[2-methoxy-5-(20-ethylhexyloxy)-p-phenylenevinylene](MEH-PPV),[6,6]-phenyl-C61-butyric acid methyl ester(PCBM) and titanium dioxide(TiO2) nanoparticles(n-type) were dissolved,mixed and deposited by physical methods(spin-coating) on indium tin-oxide(ITO) substrate.The incorporation of the titanium dioxide nanoparticles changed the morphology and increased the roughness of polymers film(MEH-PPV/PCBM),and the photocurrent density of the composite(MEH-PPV/PCBM +n-TiO2) was higher than that of single MEHPPV/PCBM film.The study showed that the presence of n-TiO2 particles in the polymeric film improves the photoelectrochemical properties of MEH-PPV/PCBM composite.
Poly (2-methoxy-5- (20-ethylhexyloxy) -p-phenylenevinylene] (MEH-PPV), [6,6] -phenyl-C61- butyric acid methyl ester (PCBM) -type) were dissolved, mixed and deposited by physical methods (spin-coating) on indium tin-oxide (ITO) substrate. The incorporation of the titanium dioxide nanoparticles changed the morphology and increased the roughness of polymers film (MEH-PPV / PCBM ), and the photocurrent density of the composite (MEH-PPV / PCBM + n-TiO2) was higher than that of single MEHPPV / PCBM film. The study showed that the presence of n-TiO2 particles in the polymeric film improves the photoelectrochemical properties of MEH-PPV / PCBM composite.
