Research Abstract

The effects of the molecular orientation and the electronic structure at the interface between molecule and metal atoms were studied aiming at an improvement of organic solar cell performance. It was found that the molecular orientation is controllable by inserting a thin buffer layer and that the molecular orientation is one of the important factors to improve the device performance. Formation of interface states through an interaction between LUMO and metal atomic orbitals was confirmed by ultraviolet electron spectroscopy and the simulation of density functional theory. It is suggested the interaction between LUMO and metal atomic orbitals plays an important role in electron transport at the metal/molecule interface.
