Inverted-structure polymer solar cells (I-PSCs) containing sequentially sprayed electron-transporting layers (ETLs) and photoactive layers were fabricated. Low-temperature sol–gel-derived ZnO thin films were used as the ETLs and films of a poly(3-hexylthiophene) (P3HT)/[6,6]-phenyl-C61-butyric acid methyl ester (PCBM) blend were used as the photoactive layers. Nanoripples-containing ZnO ETLs could...
ZnO nanorods were synthesized on carbon nanotube (CNT) yarns by an electrochemical deposition method. The grown ZnO shapes varied from a sharp cone-type nanorod to a hexagonal type nanorod according to the increase of counter electrodes. A hexagonal type nanorod changed about 0.3% of its static dimension when it was exposed to an external electric field. From an external pressure with a constant force...
