Research Abstract

In this study, we came up with new ways of thinking about organic semiconductor devices(organic light emitting diode, organic transistor, organic solar cell) by using inorganic semiconductor. As a result, the performances of organic devices were improved. We proposed the inverted organic light emitting diode using AZO thin film for high luminance. In organic transistor, we succeeded to fabricate organic transistor with high current density by using band conduction materials. In addition to these organic devices as mentioned above, we fabricated new concept organic solar cell with the effect of photosynthesis promotion.

  • [Remarks] フレキシブルプラスチック基板上に作製した折り曲げ可能な縦型有機トランジスタでは、低電圧で大電流駆動が可能であり、有機ELディスプレー駆動に必要なレベルを達成し、論理回路においても低電圧化での動作を実証している。この成果は、研究責任者である渡邊康之が研究開発した成果であり、国際会議のホームページ(29 July 2009、: SPIENewsroom)でも取り上げられ、国内外で注目される技術の一つとなっている。
