A significant enhancement of efficiency in thieno[3,4-b]-thiophene/benzodithiophene:[6,6]-phenyl C71-butyric acid methyl ester (PTB7:PC70 BM) solar cells can be achieved by methanol treatment. The effects of methanol treatment are shown in an improvement of built-in voltage, a decrease in series resistance, an enhanced charge-transport property, an accelerated and enlarged charge extraction, and a reduced charge recombination, which induce a simultaneous enhancement in open-circuit voltage (Voc), short-circuit current (Jsc), and fill factor (FF) in the devices.
甲醇处理可显著提高噻吩[3,4-b]噻吩/苯并二噻吩[6,6]-苯基 C71-丁酸甲酯（PTB7:PC70BM）太阳能电池的效率。甲醇处理的效果表现为内置电压提高、串联电阻降低、电荷输运性能增强、电荷提取加速和扩大、以及电荷复合减少，这导致器件的开路电压（Voc）、短路电流（Jsc）和填充因子（FF）同时提高。
