초록

Two isomeric organic dyes, JK-51 and JK-52 containing benzo[cd]indole were synthesized. Under standard global AM 1.5 solar condition, the JK-51 sensitized cell gave a short circuit photocurrent density of 17.43 mA/cm(2), open circuit voltage of 0.680V, and a fill factor of 0.71, corresponding to an overall conversion efficiency 21 of 8.42%. On the other hand, a solar-to-electric conversion efficiency of 6.88% was achieved with the isomeric dye JK-52. We found that the power conversion efficiency was shown to be quite sensitive to the isomeric configurations. (c) 2008 Elsevier B.V. All rights reserved
