We
report on photovoltaic cell devices based on metallo phthalocyanine structures,
such as zinc and nickel phthalocyanines (ZnPc and NiPc), which are formed by
4-(Diphenylamino) benzaldehyde containing substituents D-π-D features were
synthesized and used for dye-sensitized solar cells (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 (PCE) because of the significant improvements in short-circuit
photocurrent (Jsc) and open-circuit voltage (Voc). 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.
