借助光导原子力显微镜，展示了分子设计在决定有机光伏性能中的微妙作用。使用导电和光导AFM对含有BP和PCBM或PCBNB的p/i/n架构的OPV器件的每一层进行表征，以深入了解这些器件整体性能不同的原因。结果表明，层的化学结构的微小变化可以对薄膜的形貌、相分离和器件性能产生重大影响。
The subtle role of molecular design in determining organic photovoltaic performance is demonstrated with the aid of photoconductive atomic force microscopy. Each layer of OPV devices with a p/i/n architecture containing BP and PCBM or PCBNB is characterized using conducting and photoconducting AFM to gain insight as to why these devices perform differently in the bulk. The results illustrate how a slight change in the chemical structure of the layers can have a large impact in the film morphology, phase separation, and the device performance.
