我们已经开发出一种高效的，青色的，和新颖的方酸染料敏化ZnO太阳能电池，在630 nm处产生最大的入射光-电子转换效率（IPCE）为59%。通过具有大体积基团以防止染料聚集的Sq 3敏化的太阳能电池在标准AM 1.5照射（100 mW cm（-2））下实现了1.5%的太阳能-电转换效率（q），短路电流密度为4.04 mA cm（-2），开路光电压为0.61 V，填充因子为0.61。
We have developed an efficient, cyan-colored, and novel squaraine-dye-sensitized ZnO solar cell, producing a maximum incident photon-to-electron conversion efficiency (IPCE) of 59% at 630 nm. The solar cell sensitized by Sq 3 having bulky groups to prevent aggregation of dyes has achieved a 1.5% solar-to-electricity conversion efficiency (q) with a short-circuit current density of 4.04 mA cm(-2), an open-circuit photovoltage of 0.61 V, and a fill factor of 0.61 under standard AM 1.5 irradiation (100 mW cm(-2)).
