Abstract

A quantum dot sensitized solar cell based on a porous ZrO₂ film, sensitized with CdSe quantum dots using CdS as an intermediate layer is presented. We observe electron injection from photo-excited quantum dots into the ZrO₂, which is unexpected due to the much higher conduction band edge (closer to the vacuum level) of bulk ZrO₂ compared to TiO ₂.
