We report on the efficiency improvement of organic solar cells (OPVs) based on the low energy gap polyfluorene derivative, APFO-3, and the soluble C60 fullerene PCBM, upon addition of a residual amount of poly (4-vinylpyridine) (PVP). We find that the addition of 1% by weight of PVP with respect to the APFO-3 content leads to an increase of efficiency from(More)
—Biocellulose and biocellulose composites are being investigated as substrates and as gate dielectrics for organic field effect transistors. Spin coated films of regioregular poly(3-hexylthiophene) (RR-P3HT) and thermally evaporated pentacene were used as semiconducting materials. Preliminary results on device characteristics are reported.
