| Research Abstract |
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.
