| Research Abstract |
We have studied on the developments of next-generation organic photovoltaic devices based on photo-electronic processes of rapid and high-efficient photo-induced charge transfer. We have fabricated device structures based on random and condensed organic/ organic or organic/ inorganic interpenetrating interfaces. We have developed the fabrication technique, and realized to control the nano-structure, the size of which was comparable with an exciton diffusion length in organic solid films. We have also developed the fabrication technique of crystallization or molecular alignment in the interpenetrating bi-layer structures of donor and acceptor, resulting in the marked improvement of photovoltaic properties and photo-conversion efficiency.
