Enhanced power conversion efficiency in polymer solar cells is achieved by surface energy control. Surface modification based on a mixed self-assembled monolayer allows the independent control of the surface energy and work function. These results demonstrate that controlling the surface energy of a buffer layer that lies underneath a photoactive layer is an effective method for improving the performance in polymer solar cells.
