Abstract: The project plans the synthesis of new dye molecules and new ZnO photoanodes to be tested in dye-sensitized solar cells.
The general idea to design a metal-free organic dye is to have the dye with a D--A configuration, i.e., a donor group (D) for pushing the electrons, an acceptor group (A) for pulling the electrons, the -conjugated bridge to connect between D and A species, and an anchoring group linked to A to attach to the surface of ZnO. In this project we will use the triphenylamine derivatives for donor substitutes and cyanoacrylic acid or rhodanine-3-acetic acid groups for acceptor substitutes.

The new photoanodes will be sensitized with the new dye molecules and the corresponding devices will be assembled and tested. Benchmarking commercial dyes on ZnO photoanodes and the new dyes on commercial TiO2 photoanodes will be also applied to investigate the improved functional properties of the new ZnO-based DSSCs with respect to consolidated systems.
