| Outline of Annual Research Achievements |
This research is focuses on development of perovskite solar cells employing SWCNT electrodes having the ability to outperform the metal electrode. The lifetime of the device also can be longer in terms of thermal and chemical stability by adding antioxidant doping. This will solve the current problems of perovskite solar cell technology. In addition, we are negotiating the use of new heterostructures of SWCNT-graphene and MoS2@SWCNT for the next stretchable and tandem solar cell devices, respectively. The achievements include;
-Co-authored publication of review article entitled ‘Single‐Walled Carbon Nanotubes in Emerging Solar Cells: Synthesis and Electrode Applications’in Adv. Energy Mater. (IF: 21.875).
-Fabrication of high-performance perovskite solar cell using doped-SWCNT achieved with ~18.7% of power conversion efficiency.
-Fabrication of highly stable perovskite solar cells employed Li@C60 as antioxidant on laminated SWCNT electrode achieved with ~17.5% of power conversion efficiency.

| Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
-Finalizing the experiments for the stability test of the high performance SWCNT-based perovskite solar cells.
-Understanding the antioxidation and doping effect of Li@C60 on SWCNT electrode for stable solar cell devices.
-Preparing two manuscripts for submission in high-impact journals.
Obstacles: We are recently trying to certify the photoconversion efficiency of our produced solar cells. The are a lot of restrictions according to measurement’s standards. Therefore, we negotiate the collaboration with different teams in Japan for this issue.
