In article number 1301354, Yasuo Nakayama and co‐workers report the discovery of a very tiny density of “gap states” at the acceptor (C60)/buffer (bathocuproine, BCP) interface using low‐energy ultraviolet photoelectron spectroscopy with very high sensitivity. Energy levels and electrostatic potential distribution are demonstrated for the complete device structure under sun light illumination using this technique.
