聚合物太阳能电池是由最近合成的低带隙交替聚芴共聚物APFO - Green2与有机溶液中的[6,6]-苯基- C61 -丁酸甲酯（PCBM）结合而成。太阳能电池的外量子效率（EQEs）在850 nm处开始，在650 nm处出现bbb10 %的峰值，这与聚合物的扩展吸收光谱相对应。在太阳模拟器空气质量1.5 (AM 1.5) （1000 W m-2）的光照下，基于这种新型低带隙聚合物的太阳能电池的光电流为3.0 mA cm-2，光电压为0.78 V，功率转换效率为0.9%。
Polymer solar cells have been fabricated from a recently synthesized low band‐gap alternating polyfluorene copolymer, APFO‐Green2, combined with [6,6]‐phenyl‐C61‐butyric acid methyl ester (PCBM) from organic solutions. External quantum efficiencies (EQEs) of the solar cells show an onset at 850 nm and a peak of > 10 % located at 650 nm, which corresponds to the extended absorption spectrum of the polymer. Photocurrent of 3.0 mA cm–2, photovoltage of 0.78 V, and power conversion efficiency of 0.9 % have been achieved in solar cells based on this new low‐bandgap polymer under the illumination of air mass 1.5 (AM 1.5) (1000 W m–2) from a solar simulator.
