摘要

Using electrode buffer layer is one of effective ways to enhance electric performances of organic solar cells. And LiF is the widest materials, which is used as a cathode buffer layer. In this paper, small molecule organic solar cells based on ZnPc and C60 are fabricated. And the LiF cathode buffer layer is studied. The mechanisms and functions of LiF layer are summarized and qualitatively explained. The thickness of LiF is also investigated. And it is found that its optimum thickness must be controlled at the interval from 1.0nm to 1.5nm.
