Nanostructured ZnO, TiO2, and Composite ZnOTiO2 Films for Application in Dye-Sensitized Solar Cells

Abstract EN

The effects of using composite semiconductor films on the efficiency and stability of dye-sensitized solar cells (DSSCs) were investigated.

Four different types of composite ZnO/TiO2 cells were developed and sensitized with the organic molecules Coumarin 343 (C343) and Rose Bengal (RB).

A comparative assessment of the different composite cells was conducted, and the photovoltaic performance of single-semiconductor ZnO and TiO2 solar cells was also compared to that of the composite ZnO/TiO2 cells.

It was observed that composite cells with ZnO/TiO2 ratio equal to 90/10 have comparable efficiency to single-semiconductor cells and have the advantage of higher stability.

The effects of using various multicomponent electrolytes on the efficiency and stability of the ZnO/TiO2 cells were also investigated.

It was observed that the combined properties of the materials used in these electrolytes enhance the efficiency of the composite ZnO/TiO2 cells.
