Abstract
The field dependence and yield of free charge carrier generation in polymer:fullerene blends with varying energetic offsets is not affected when the excitation energy is varied from above band-gap to direct CT state excitation. Instead, the ability of the CT state to split is dictated by the energetic offset between the relaxed CT state and the charge separated (CS) state.
摘要
当激发能从带隙以上变为直接 CT 态激发时，具有不同能量偏移的聚合物：富勒烯混合物中自由电荷载流子生成的场依赖性和产率不会受到影响。相反，CT 态的分裂能力由弛豫 CT 态和电荷分离（CS）态之间的能量偏移决定。
