Synthesis of Conjugated bis-Schiff Base and Their Complexes as Dye-Sensitizer for Dye Sensitized Solar Cell (DSSC) Application

Schiff base and their metal complexes have been widely used as photovoltaic materials due to excellent π-electron transfer properties along the molecule. A total of eleven conjugated symmetrical bis-Schiff with different π-spacers synthesized spectroscopically characterized in order investigate conversion efficiency dye-sensitizer solar cells (DSSC). All compounds were either substituted hydroxy (-OH) or methoxy (-OMe) electron donor difluoro boron (BF2) acceptor without any substituent. applied DSSC using titanium (IV) oxide (TiO2) coated on a fluoride doped tin glass working electrode electric paint containing carbon black, whereas graphene indium counter electrode. The power efficiencies bases compared N3 Dye benchmark standard. results showed that compound aromatic ring bridge π-spacer -OMe substituent gave highest at 0.0691% BF2 lowest 0.0012%.
