摘要
The ultrafast dynamics at a well-characterized CuPc/C-60 organic photovoltaic heterojunction have been directly measured with time-resolved two-photon photoemission (TR-2PPE). Phthalocyanine/C-60 donor-acceptor interfaces, characterized in detail via scanning tunneling microscopy, provide model systems for studies of critical charge separation and recombination processes that determine device performance. TR-2PPE studies of copper phthalocyanine (CuPc)/C-60 interfaces reveal ultrafast charge separation and provide evidence for recombination via low-lying CuPc triplet levels.
