We synthesized a diporphyrin compound [4,7-bis[5-[arylethynyl]-10,20-bis(triisopropylsilyl)ethynyl}porphyrin-15-yl]]-2,1,3-benzothiadiazole dimagnesium(II)], in which two porphyrin units were linked using a benzodiathiazole unit as an electron-withdrawing moiety. These diporphyrins have low-lying HOMO and LUMO levels with long-wavelength light absorption property. Power conversion efficiency of the organic solar cell using this diporphyrin and mix-PCBM (a 85:15 mixture of [6,6]-phenyl- C 61-butyric acid methyl ester ( PC 61 BM ) and [6,6]-phenyl- C 71-butyric acid methyl ester ( PC 71 BM ) was 2.75% with short-circuit current density of 8.79 mA/cm2, open-circuit voltage of 0.80 V, and fill factor of 0.39. Photocurrent conversion in the near infrared region was demonstrated by the incident photon-to-current efficiency spectrum.
