Titanium oxide particles
Graduate school engineering course professor and chair Doctor of Engineering, Tsutomu Miyasaka
Assignment: evenly disperse nano-level titanium oxide particles and obtain paste without air bubbles Case example: nano particle dispersion and deaeration performance contributed to creating of suitable paste
Dye sensitized solar cells are the next generation solar cells that most of film- and optics-related companies study and develop. This solar cells use thin resin material instead of hard materials such as glass or silicon. They are flexible and light, easy to transport, hard to break, and able to generate electric power even if they are bended. Design for our solar cells can be created with commonly used printing method, enabling easy mass-production. Production cost is lowered to 1/10 of traditional silicon solar cells. The issues we have are improvement of durability and power generation efficiency.
What's important here is to figure out well-balanced ratio of water and alcohol, type of pigment, electrolysis solution ratio for when impasting titanium. The most important of all is to turn 20 nano meter size titanium oxide particles into milky liquid form and create the viscosity that stays on when applied onto plastic surface. In this process, THINKY MIXER is essential. Without it, the fine titanium oxide paste, the core of the technology cannot be created. It may be possible to create it in some other way, but that would probably take 10 times longer and cost a lot more. If our dye sensitized solar cells are put into practical use, they would become "unbreakable solar cells" that can be familiar to general consumers. We expect new needs such as turning them into drapes and placing them on bags.
