Abstract
We have designed and synthesized a new unsymmetrical zinc phthalocyanine based on ‘push-pull’ and extended π-conjugation concept, PCH008. The new sensitizer was fully characterized by CHN anlysis, UV-Vis., fluorescence spectroscopies and cyclic voltammetry. The new sensitizer which upon anchoring onto nanocrystalline TiO2 film exhibit a short circuit current of 5·63 mA cm−2, open circuit potential of 557·0 mV and a fill factor of 0·75 corresponding to an overall conversion efficiency of 2·35% under standard global air mass (AM) 1·5 solar conditions and compared its performance with literature reported phthalocyanine dyes.
