| Research Abstract |
Correlation between the interfacial electronic structure and device performance of organic photovoltaics is indispensible to provide well-defined guidelines for highly efficient organic photovoltaics(OPVs). In this research, we first elucidated the distribution of the internal potential in planar heterojunction OPVs using Kelvin probe method. Secondly, the electronic structure at donor/acceptor interface could be modified by the control of substrate work function. Based on this finding, it was found that the formation of the interfacial dipole at the donor/acceptor interface strongly influences photocurrent generation
