In summary, we have successfully synthesised novel HKK-Por
dyes and obtained materials with interesting optical and electro-
chemical properties. Among the series of HKK-Por dyes, which
had a different
p-conjugating system and similar electron donor
moieties, the value of HKK-Por1 was relatively large, but the rel-
e
ative quantum efficiency of HKK-Por2 was a little high. Under
standard global AM 1.5 solar conditions, the HKK-Por1 sensitiser
cell gave a JSC of 10.7 mAcmꢁ2, VOC of 0.67 V, and FF of 0.70, corre-

improvement of the power conversion efficiency of porphyrin
derivative dyes can be investigated by using them as dye sensitis-
ers instead of expensive ruthenium dye sensitisers in the near
future.
