Key metrologies/systems: Scanning tunneling microscopy and one- and two-photon photoemission/Model organic heterostructures - pentacene:C60 and metal phthalocyanine:C60. Advanced platforms and protocols are being developed towards innovative metrologies to fully characterize the charge transfer dynamics of next-generation organic photovoltaic systems.
Electronic Structure and Excited-State Dynamics at Donor-Acceptor Interfaces
Organic photovoltaic cells rely upon molecular interfaces to separate charge. Efficient charge separation depends molecular structure and electronic band alignment across donor-acceptor interfaces. Correlation of molecular structure determined with scanning tunneling microscopy and interfacial electronic structure measured with one- and two-photon photoemission techniques allows determination of the factors that control the efficacy of charge separation.
