Zinc phthalocyanine sensitizer having double carboxylic acid anchoring groups for dye-sensitized solar cells with cobalt(II/III)-based redox electrolyte

摘要

Red-absorbing zinc phthalocyanine (ZnPc) PcS25 with double carboxylic acid anchors has been synthesized and used as the sensitizer for dye-sensitized solar cells with cobalt(II/III)-based redox electrolyte. Double anchored ZnPc sensitizer PcS25 exhibited higher conversion efficiency than single-anchored sensitizers.
