N2 - We report a rational design and engineering of quantum dot sensitized nanostructured solar cells (QDSNSC) by utilizing quantum dots (QDs) (e.g., CdSe QDs) into vertically oriented TiO2 nanotubes fabricated by electrochemical anodization. A water soluble bifunctional group (i.e., dithiocarbamate) capped CdSe QDs is synthesized via a biphasic ligand exchange. The -COOH group at the dithiocarbamate functionalized CdSe QDs surface reacts with the -OH group at the TiO2 nanotube surface, thereby facilitating interfacial interaction between the electron donor (i.e., CdSe) and electron accepter (i.e., TiO2). The effects of the size of CdSe QDs and the aspect ratio of nanotubes on the performance of QDSNSC are studied.
