  • Visible-pump / X-ray probe photoelectron spectroscopy monitors exciton migration and charge generation in a molecular heterojunction between a copper-phthalocyanine (CuPc) donor and a fullerene-based (C60) acceptor. Singlet excitons in the interfacial region (blue) dominate charge generation on the shortest timescales. On longer timescales, however, triplet excitons from excitations within the bulk material (red) contribute the majority of generated charges, ultimately dominating the time-averaged charge generation yield.
