Narrow bandgap conjugated polymers in combination with fullerene acceptors are under intense investigation in the field of organic photovoltaics (OPVs). The open circuit voltage, and thereby the power conversion efficiency, of the devices is related to the offset of the frontier orbital energy levels of the donor and acceptor components, which are widely determined by cyclic voltammetry. Inconsistencies have appeared in the use of the ferrocenium/ferrocene (Fc + /Fc) redox couple, as well as the values used for the absolute potentials of standard electrodes, which can complicate the comparison of materials properties and determination of structure/property relationships.
在有机光伏领域，窄带隙共轭聚合物与富勒烯受体的组合受到了广泛关注。器件的开路电压，进而功率转换效率，与供体和受体组分的前沿轨道能级的偏移有关，而这些能级的偏移通常由循环伏安法确定。在使用 ferrocenium/ferrocene（Fc+/Fc）氧化还原对以及标准电极的绝对电势值方面存在不一致，这可能会使材料性能的比较和结构/性能关系的确定复杂化。
