Chapter 51 Deposition of Perylene Diimide Derivatives for Dye-Sensitized Solar Cells

摘要

The aim of this work is to examine the photosensitivity of dye-sensitized materials. Three types of organic dye sensitizers, i.e. perylene diimide (PDI) derivatives with different terminal groups were synthesized. The synthesized PDI derivates were deposited by dipping on a glass/ITO substrate covered with arrays of ZnO nanorods (NR) grown by an electrochemical process. An Ag grid contact was deposited on the PDI films on the stack glass/ITO/ZnONR/PDI; then I-V characteristics of the structures were measured in dark and under illumination with a halogen lamp. The photosensitivity of the different dye-sensitized materials is discussed.
