摘要：

Here comes the sun: A conversion efficiency as high as 5.4% has been achieved on dye-sensitized ZnO solar cells with photoelectrode films consisting of poly-disperse aggregates, compared to 2.4% for the films with only nanosized crystallites. The aggregation of nanocrystallites with a broad size distribution is effective in enhancing the light-harvesting efficiency by inducing light scattering within the photoelectrode films.
