Materials Environment Durability improvement of perovskite solar cells by
diamond-like carbon coating  |
 |
| Professor SUZUKI, Tetsuya Department of Mechanical Engineering |
||
|
Perovskite solar cells, which are attracting attention as low-cost, high-efficiency solar cells, deteriorate with time and conversion efficiency decreases. We aim to improve the durability of perovskite solar cells by coating diamond-like carbon with excellent gas barrier properties and light transmission on perovskite solar cells.

Materials Industry Nano-Processing of Next Generation Materials
 |
 |
| Professor YAN, Jiwang Department of Mechanical Engineering |
||
|
We develop new technologies for nano-scale processing and surface property control of materials in order to improve the functional capability and added value of industrial products. We deal with super hard alloys, ceramics, semiconductors, diamond, CFRP, and so on. Recently, we have succeeded in generation of silicon nanostructures by laser irradiation on waste silicon sludge to produce high-performance lithium-ion batteries.

Materials Industry High-performance Optical Component Fabrication
 |
|
| Professor YAN, Jiwang Department of Mechanical Engineering |
||
|
We develop new fabrication technologies for nano-precision free-form optics and their molds by using multi-axis numerical control ultraprecision machines. High-speed surface finishing of optical crystals, such as Si, Ge, ZnSe, CaF2, etc. has been realized by ductile machining technology. Recently, we also succeeded in fabricating ultra-thin Si-HDPE hybrid lenses for future IR devises.
