摘要：

Interface disorder comprehensively explains the up-and-down (or vice versa) energy shift commonly measured for molecular donor-acceptor interfaces including those used in organic photovoltaics. Full characterization of such interfaces with photoelectron spectroscopy and complementary electrostatic calculations reveal that electronic tail states, induced by disorder, lead to the complex energy level alignment observed. © 2015 WILEY-VCH Verlag GmbH & Co.
