A new transient charge extraction technique is presented, which facilitates simultaneous measurements of mobility and lifetime of photogenerated charge carriers in organic solar cells under real operating conditions. An adaptive field control is implemented keeping the solar cell at open circuit conditions during recombination. The practical benefit of the new technique is demonstrated by determining the mobility-lifetime parameter of solar cells based on PCDTBT:PC(71) BM and P3HT:PC(61) BM.
提出了一种新的瞬态电荷提取技术，该技术可在实际工作条件下同时测量有机太阳能电池中光生电荷载流子的迁移率和寿命。通过在复合过程中保持太阳能电池开路条件，实现了自适应场控制。通过基于 PCDTBT：PC（71）BM 和 P3HT：PC（61）BM 的太阳能电池的迁移率-寿命参数的确定，证明了该新技术的实际效益。
