A derivative of the two dye-sensitized enough enemy types, which are composed of a base. The electron donor and an electron acceptor. Were synthesized for use in dye sensitized by
3,4,5-trimethoxybenzaldhyde As the electrons of the two dyes. Which Pzn-COOH A carboxyl functional groups as electron acceptor and Pzn-BIA-COOH A carboxyl functional elements such as an electron, but with increasing π-Spacer is Schiffbase Struture. The individual dyes are absorbed on titanium dioxide Nth different. The study found that dye-sensitized enough enemy Pzn-BIA-COOH Birth red-shifted. There is a broadened electronic spectra respect to the reference PZnACOOH as expected. Schiff base unit is expected to add to the meso position energy leval of excited-state oxidation potentials The highest power conversion efficiency of the two dyes based on DSSCs reached 1.75% under AM 1.5 G irradiation.
