PCPDTBT是一种边缘可结晶的聚合物，使用溶剂蒸气退火使其结晶成新的晶体结构。使用TEM/艾德，GIWAXS，和偏振拉曼光谱与三种不同的聚合物链取向的高度有序的地区。的光学和结构特性显着不同的膜制备的标准设备的准备方案。然而，双层太阳能电池显示出类似的性能。
PCPDTBT, a marginally crystallizable polymer, is crystallized into a new crystal structure using solvent-vapor annealing. Highly ordered areas with three different polymer-chain orientations are identified using TEM/ED, GIWAXS, and polarized Raman spectroscopy. The optical and structural properties differ significantly from films prepared by standard device preparation protocols. Bilayer solar cells, however, show similar performance.
