Abstract :We report on photovoltaic cell devices based on metallo phthalocyanine structures, such as zinc and nickel phthalocyanines insert ignore into journalissuearticles values(ZnPc and NiPc);, which are formed by 4-insert ignore into journalissuearticles values(Diphenylamino); benzaldehyde containing substituents D-π-D features were synthesized and used for dye-sensitized solar cells insert ignore into journalissuearticles values(DSSCs);. These novel compounds were characterized by using FTIR, UV-vis, MS spectroscopic data and elemental analysis. Furthermore, the relationship between ZnPc and NiPc morphology and photovoltaic properties are discussed. Among ZnPc and NiPc, the ZnPc-DSSC exhibited significantly excellent photovoltaic activities under radiation of visible light. In this case, photovoltaic cell efficiencies are up to 1.139% for ZnPc, compared to an average of 0.427% for NiPc. Moreover, the ZnPc device prepared at room temperature exhibits relatively higher photovoltaic cell efficiency insert ignore into journalissuearticles values(PCE); because of the significant improvements in short-circuit photocurrent insert ignore into journalissuearticles values(J sc ); and open-circuit voltage insert ignore into journalissuearticles values(V oc );. However, a DSSC assembled with NiPc material due to metallic behavior of nickel in the structures electrochemical reactions run at the interface between NiPc and back contact, which causes electrochemical corrosion of metal. Thus NiPc-DSSC shows lower photovoltaic properties than ZnPc-DSSC.
