使用氯苯作为基础溶剂的沉积的聚（3-己基噻吩-2，5-二基）（P3 HT）层中的P3 HT：苯基-C61-丁酸甲酯扩散双层太阳能电池，我们研究了添加少量的高沸点溶剂具有相似的化学结构上得到的活性层的形貌的影响。结果表明，P3 HT薄膜的结晶度以及在有源层中的垂直施主-受主梯度可以通过这种方法来调节。高沸点溶剂的使用改善了所有光伏参数，并导致功率转换效率提高了32%。
Using chlorobenzene as a base solvent for the deposition of the poly(3-hexylthiophene-2,5-diyl) (P3HT) layer in P3HT:phenyl-C61-butyric acid methyl ester diffusive bilayer solar cells, we investigate the effect of adding of small amounts of high-boiling-point solvents with similar chemical structures on the resulting active layer morphologies. The results demonstrate that the crystallinity of the P3HT films as well as the vertical donor–acceptor gradient in the active layer can be tuned by this approach. The use of high-boiling-point solvents improved all photovoltaic parameters and resulted in a 32% increase in power conversion efficiency.
