| Research Abstract |
I have tried to investigate the fabrication of P-N-nano-structure and its application to organic thin film solar cells. I chose the fullerene derivative and liquid crystalline materials as N-type and P-type semiconductors, respectively. In the materials having lower ordered liquid crystal phases, the liquid crystal phase disappeared in low-concentration mixture with fullerene derivative(less than several%). On the other hand, in the material having highly ordered liquid crystal phase, mesophase appeared in spite of high-concentration mixture with fullerene. This fact indicates that the highly ordered liquid crystal is very effective for fabrication of nano-structure using liquid crystal phase. I also developed liquid crystalline materials having highly ordered liquid crystal phase and measured their carrier transport properties, and developed fabrication of very uniform thin film using liquid crystal phases.
