High-efficiency dye-sensitized solar cells of up to 8.03% by air plasma treatment of ZnO nanostructures†
Abstract
By using the simple but effective method—air plasma to treat the precursor Zn(OH)2, the hydrogen-related defects in ZnO, which lead to increased charge carrier recombination, have been reduced. Successfully, a photoelectric conversion efficiency of 8.03% for pure ZnO-based DSSCs has been achieved, which is the highest one up to now.
