Outline of Annual Research Achievements

This project targets at high-efficiency of organic and perovskite solar cells, and at the same time investigate the underlying mechanisms of fluid-nanomaterials interaction. The research achievement is summarized as follows:
1 We have proposed a new architecture for organic solar cell which employs molybdenum oxide-SWNT nanocomposite layer as transparent electron blocking electrode. The low-lying work function of molybdenum oxide served as p-type dopant for SWNTs, which results in a three-fold decrease in the sheet resistance of SWNTs. The doping effect of molybdenum oxide was confirmed by UV-vis-NIR absorption spectroscopy and photoelectron yield spectroscopy. The SWNT organic solar cell in this work showed a power conversion efficiency of 6.04%. Flexible application shows 3.91% efficiency and is capable of withstanding a severe cyclic flex test. The research results were published in Journal of the American Chemical Society.
2 We further investigated the breath-figure interaction between fluid and SWNTs by modulating the diameters of SWNTs. We have proposed a new catalyst design paradigm which utilizes the anchoring effect between Co and Cu. The diameter of SWNTs was reduced from 2 nm to 0.75 nm, with the Raman G/D ratio kept over 30. The result has been submitted to Nanoscale (now under review) presented in several conferences as invited speech (see 学会発表).
The fluid-nanomaterial interaction and additive manufacturing of SWNT architecture will be continued at MIT under the support of MIT-UTokyo International Science and Technology Initiative.
