采用有机墨水喷雾打印技术制备了聚合物太阳能电池的有源层。筛选出各种高沸点的溶剂和添加剂，以制备高质量的聚合物薄膜。研究了热处理和溶剂蒸气退火对薄膜器件性能的影响。溶剂的组成对控制液膜的干燥速度，减少膜表面的颗粒状突起，实现聚合物相中的高分子有序化具有重要意义。优化后的聚3-己基噻吩基C(60)衍生物太阳能电池器件的填充因子高达67%，功率转换效率为2.53%。Poly[N-9-heptadecanyl-2，7-carbazole-alt-3，6-bis(thiophen-5-yl)-2，5-diethylhexyl-2，5-dihydropyrrolo-[3，4-]pyrrole-1，4-dione]和C(70)衍生物的组合使器件面积分别为0.03和1 cm(2)时的功率转换效率分别为3.92%和3.14%。
Active layers of polymer solar cells were prepared by aerosol jet printing of organic inks. Various solvents and additives with high boiling points were screened for the preparation of high-quality polymer films. The effects on device performance of treating the films by thermal and solvent vapor annealing were also investigated. The components of the solvent were important for controlling the drying rate of the liquid films, reducing the number of particle-like protrusions on the film surface, and realizing high molecular ordering in the polymer phases. The optimized solar cell device with poly(3-hexylthiophene) and a C(60) derivative showed a high fill factor of 67% and power conversion efficiency of 2.53% without thermal annealing. The combination of poly[N-9-heptadecanyl-2,7-carbazole-alt-3,6-bis(thiophen-5-yl)-2,5-diethylhexyl-2,5-dihydropyrrolo-[3,4-]pyrrole-1,4-dione] and a C(70) derivative led to power conversion efficiency of 3.92 and 3.14% for device areas of 0.03 and 1 cm(2), respectively.
