Abstract
Three organic sensitizers, JK-128, JK-129, and JK-130 containing quinoline unit are designed and synthesized. Under standard global AM 1.5 solar condition, the JK-130 sensitized solar cell gave a short circuit photocurrent density of 11.52 mA cm-2, an open circuit voltage of 0.70 V, and a fill factor of 0.75, corresponding to an overall conversion efficiency of 6.07%. We found that the η of JK-130 was higher than those of other two cells due to the higher photocurrent. The higher Jsc value is attributed to the broad and intense absorption spectrum of JK-130.
