摘要

Solution-processed transparent electrodes made from silver-nanowires and peroxo-polytitanic (PPT) acid gel were developed for enhancing efficiency of organic solar cells. The electronic and optical properties of multilayer silver nanowires were significantly improved through the interconnection layers of amorphous titanium oxide (TiOx) from PPT acid gel. The AgNW-TiOx composite film showed averaged 92.14% optical transmittance with only 16.01 Omega sq(-1) sheet resistance. Combining the transparent electrodes with poly(3-hexylthiophene):[ 6,6]-phenyl-C61-butyric acid methyl ester (P3HT: PC61BM) blend, the efficiency of organic solar cells was 1.45 times that of devices using an ITO electrode. Optical simulations verified that the improvement was attributed to the enhanced near-field absorption and substantial scattering of incident light resulted from the random nature of the AgNW-TiOx core-shell nanostructure.
