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.

本项目以有机和钙钛矿太阳能电池的高效率为目标，同时研究流体-纳米材料相互作用的潜在机制。主要研究成果如下：1提出了一种新型的有机太阳能电池结构，该结构采用氧化钼-碳纳米管纳米复合层作为透明电子阻挡电极。氧化钼的低位功函数作为单壁碳纳米管的p型掺杂剂，使单壁碳纳米管的方阻降低了三倍。通过UV-VIS-NIR吸收光谱和光电子产额谱证实了氧化钼的掺杂效应。本文所研究的单壁碳纳米管有机太阳能电池的功率转换效率为6.04%。灵活的应用显示3.91%的效率，并能够承受严重的循环弯曲测试。研究结果发表在《美国化学学会杂志》上。2我们通过调节单壁碳纳米管的直径，进一步研究了流体与单壁碳纳米管之间的呼吸-图形相互作用。我们提出了一种利用钴和铜之间的锚定效应来设计催化剂的新范式。单壁碳纳米管的直径从2 nm减小到0.75 nm，拉曼G/D比保持在30以上。这一成果已作为特邀演讲(见学会発表)提交给纳米尺度(目前正在审查中)的几个会议。在麻省理工学院-东京大学国际科学技术倡议的支持下，单壁纳米管结构的流体-纳米材料相互作用和添加剂制造将在麻省理工学院继续进行。
