Nanoporous ZnO Photoelectrode for Dye-Sensitized Solar Cell

الملخص EN

Nanoporous and macroporous structures were prepared by using self-assembled monolayer (SAM) onto ZnO thin films in order to investigate the efficiency of dye-sensitized solar cells (DSSCs) produced using these films.

Using SAM on ZnO thin films, it is obtained successfully assembled large-area, highly ordered porous ZnO thin films.

Varying nanoporous radius is observed between 20 and 50 nm sizes, while it is 500–800 nm for macroporous radius.

The solar conversion efficiency of 2.75% and IPCE of 29% was obtained using ZnO nanoporous/N719 dye/I−/I3- electrolyte, while macroporous ZnO given solar conversion efficiency of 2.22% and IPCE of 18%.
