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.

为了提高有机太阳能电池的性能，研究了分子取向和分子与金属原子界面的电子结构的影响。研究发现，通过插入薄的缓冲层可以控制分子取向，并且分子取向是提高器件性能的重要因素之一。紫外电子能谱和密度泛函理论模拟证实了通过LUMO和金属原子轨道之间的相互作用形成界面态。这表明LUMO与金属原子轨道之间的相互作用在金属/分子界面的电子传输中起着重要作用。
