Abstract
Copper oxide (CuO) nanoparticles (<50 nm) were incorporated in the P3HT—poly(3-hexylthiophene):PCBM-[6,6]—phenyl-C61-butyric acid methyl ester bulk heterojunction organic solar cells. The ratio of P3HT to CuO in the blend was varied, while maintaining the fixed ratio of PCBM. The addition of CuO nanoparticles was found to significantly improve the power conversion efficiency in the P3HT:PCBM solar cells under AM 1.5 G and 100 mW/cm2 irradiation. The mixing of CuO in the active layer widens the light absorption range and introduced a red shift in the absorption spectra. The CuO-conjugated active layer increased the surface roughness. The CuO nanoparticles agglomerated in the blend as their concentration relative to P3HT increased in the active layer.
