Recently, ZnOnanocones with exposed {10_11} facets were prepared and used as photoanode material in a N719-sensitized solar cell, which displayed a better conversion efficiency (3.84%) than the devices fabricated with commonly used ZnOnanorods with predominantly exposed {10_10} facets due to the significantly less dye aggregation on the ZnO {10_11} facets as compared to the other ZnO facets [26].
