By further thermal annealing the ZnO embossed hybrid nanowires, a unique superhighway-like architecture which composed of alternating parallel channels of P3HT nanofibrils and ZnO nanocrystals could be further obtained. This donor/acceptor (D/A) parallel-channel structure gave access to the improvements in the exciton dissociation and charge transport, thereby enhancing photoluminescence quenching, charge transport, and device performance. The photovoltaic devices with the D/A parallel-lane structure gave a high PCE of 0.61% as compared to only 0.07% from a conventional P3HT/ZnO bulk heterojuction solar cell. Our approach offers a versatile route to coassemble inorganic nanocrystals with -conjugated polymer hosts, forming uniform one-dimensional hybrid nanochannels potentially useful in optoelectronic applications. © 2014 American Chemical Society. |
