A series circuit of bulk hetero-junction (BHJ) organic thin-film solar cells (OSCs) is investigated for electrolyzing water to gaseous hydrogen and oxygen. The BHJ OSCs applied consist of poly(3-hexylthiophene) as a donor and [6,6]-phenyl C61 butyric acid methyl ester as an acceptor. A series circuit of six such OSC units has an open circuit voltage (V(oc)) of 3.4 V, which is enough to electrolyze water. The short circuit current (J(sc)), fill factor (FF), and energy conversion efficiency (η) are independent of the number of unit cells. A maximum electric power of 8.86 mW cm(-2) is obtained at the voltage of 2.35 V. By combining a water electrolysis cell with the series circuit solar cells, the electrolyzing current and voltage obtained are 1.09 mA and 2.3 V under a simulated solar light irradiation (100 mW cm(-2), AM1.5G), and in one hour 0.65 mL hydrogen is generated.
将体异质结（BHJ）有机薄膜太阳能电池（OSC）串联用于水的电解以产生气态氢和氧。所应用的 BHJ OSC 由聚（3-己基噻吩）作为供体和[6,6]-苯基 C61 丁酸甲酯作为受体组成。六个这样的 OSC 单元的串联电路具有 3.4 V 的开路电压（V(oc)），足以进行水电解。短路电流（J(sc)）、填充因子（FF）和能量转换效率（η）与单元数量无关。在 2.35 V 的电压下，获得了 8.86 mW cm(-2)的最大功率。通过将水电解池与串联太阳能电池组合，在模拟太阳光照射（100 mW cm(-2)，AM1.5G）下，获得的电解电流和电压分别为 1.09 mA 和 2.3 V，在一个小时内可产生 0.65 mL 的氢气。
