Procreation of devices and development of metal organic decomposition inks for next generation printed electronics

研究の背景 Background


To realize the permanent sustainable human society, industrial reducing waste products of raw materials, energy consumption and greenhouse gas emissions have gained global attention in the world. Printed electronics (PEs), which can be produced electronics devices by printing method is one of the emerging manufacturing technology expected to overcome these environmental issues. Moreover, PEs technology of materials and process is actively studying and developing intended to additional wearable functions, such as flexible, stretchable, and transparent properties.

研究の目標 Outcome


Very recently, the metal organic decomposition inks for semiconductor and electrode wiring as PEs technology have developed in our research group. The organic metal salt inks, especially, precursor of oxide semiconductor ink has been developed by a variety of sintering methods such as high intense pulsed photo-sintering. The goal of the future studies, the next generation electrics devices such as the thermoelectric conversion modules, the photo voltaic solar cells, and thin film transistors as well as with the functional properties are making by combining these techniques, which contribute to the realization of future ubiquitous human society.
