我们发展了可应用于有机太阳能电池的实验和分析方法,以揭示载流子复合动力学。我们还制作了太阳能转换效率高达7%的太阳能电池,并将其用作样品。研究发现,在开路条件下,载流子以理想的双分子复合方式复合,而在短路条件下,晶区形成的载流子没有损失地被提取。此外,我们还阐明了在开路和短路之间的工作点上的复合动力学,其中陷阱载流子起着重要的作用。
英文摘要
We developed experimental and analytical methods that can be applied to working organic solar cells to reveal the carrier recombination kinetics. We also fabricated solar cells with a solar conversion efficiency up to 7%, and used them as samples. It has been found that under open-circuit conditions carriers recombine via an ideal bimolecular recombination manner, whereas carriers formed in crystalline regions are extracted without a loss under short-circuit conditions. In addition, we elucidated the recombination kinetics at working points between open and short-circuit conditions, where trapped carriers play an important role.
