以[6，6]-苯基C61丁酸甲酯(PCBM)为受体，以二氰基取代的低聚硫吩作供体，制备并表征了有机体异质结(BHJ)太阳电池。低聚硫吩衍生物能够吸收太阳辐射的长波光子，使优化重量比为1：1.4时的太阳电池在AM 1.5G光照下具有良好的短路电流密度(12.4 mA/cm~2)和开路电压(0.88V)，强度为100 mW/cm~2。获得了3.7%的功率转换效率，是溶液处理小分子BHJ太阳电池中最好的转换效率之一。
Organic bulk heterojunction (BHJ) solar cells based on a dicyanovinyl-substituted oligothiophene as a donor and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) as an acceptor were fabricated and characterized. The oligothiophene derivative can absorb long wavelength photons of the solar radiation, which makes the solar cells with an optimized weight ratio of 1:1.4 have a decent short-circuit current density (12.4 mA/cm2) and open-circuit voltage (0.88 V) under AM 1.5G illumination with an intensity of 100 mW/cm2. A power conversion efficiency (PCE) of 3.7% is achieved, which is among the best PCEs of solution processed small molecule BHJ solar cells.
