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 $\eta$ of JK-130 was higher than those of other two cells due to the higher photocurrent. The higher $J_sc}$ value is attributed to the broad and intense absorption spectrum of JK-130.
我们设计并合成了三种有机敏化剂,分别是JK-128、JK-129和JK-130,其中JK-130含有
喹啉单元。在标准全球
AM 1.5太阳光条件下,JK-130敏化太阳能电池的短路光电流密度为11.52 mA
$cm^-2}$,开路电压为0.70 V,填充因子为0.75,总转换效率为6.07%。我们发现JK-130的
$\eta$高于其他两种电池,这是由于JK-130的光电流更高。JK-130的
$J_sc}$值更高,这是由于其吸收光谱更宽、更强烈。
