Outline of Final Research Achievements

In this study, I proposed the method that can control the diameter distribution of vertically aligned CNTs by using Ink-jet printing of metal nanoparticle catalyst. In addition, the end-contacted structure, which can form CNTs and metal electrodes with good electrical connections, has been developed. The CNT-Si heterojunction solar cells have been fabricated with this end-contacted structure. The electrical measurements were performed for the characterization of this devices. These results show the photovoltaic behaviors of the new solar cell with the end-contacted structures and the possibility of making CNT-Si solar cells with better power conversion efficiency.
