- Abstract
- CeO2 nanoparticles were synthesized by using a precipitation method. High-resolution transmission electron microscopy images, X-ray diffraction patterns, energy dispersive X-ray spectroscopy spectra, and UV-Visible absorption spectroscopy spectra showed that the formed samples were CeO2 polycrystalline nanoparticles. Inverted organic solar cells with a structure of indium-tin-oxide/CeO2/poly(3-hexylthiophene) (P3HT):[6,6]-phenyl C-61 butyric acid methyl ester (PCBM)/MoO3/Ag were fabricated. Current density-voltage results showed that the power conversion efficiency of the device of the fabricated inverted OPV cells with a CeO2 interlayer between the P3HT:PCBM and the cathode was 0.39% larger than that without a CeO2 interlayer.
