A comparative study on the dye sensitized solar cell performance of solution processed ZnO

Here, we report the effect of the aspect ratio and surface area of solution processed zinc oxide (ZnO) on the performance of ZnO based dye-sensitized solar cells (DSSC). The dye sensitized solar cells constructed using the prepared ZnO nanostructures and N719 dye molecules, exhibited efficiencies that varied as a function of surface area of the samples, with ZnO prisms exhibiting a maximum efficiency of around 1.38 ± 0.01%.
