| Outline of Research at the Start |
Our original reactive polyiodide melt（RPM）method allows us to explore Pb－free Perovskite and non－Perovskite absorber layers in order to overcome the problem related to the toxicity of Pb-based compounds in the state－of－art MAPbI3 Perovskite solar cells．Using the RPM method. we will synthesize various absorber layers by replacing Pb with earth－abundant non－toxic materials (X). The RPM method，which is of great interest to academia and industry，opens a new route to realize eco－friendly，stable and efficient solar cells in the best interest of our society．

| Outline of Annual Research Achievements |
This year, I further investigated by XRD the formation of MASnI3 film made by reacting Sn metal film with MAI vapor at 130 and 150C. I observed that the reactions paths lead to different products and investigated the possible reactions mechanisms. The results were reported at the conference.

| Current Status of Research Progress |
Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
Progress is in accordance with our research plan, although delayed due to the working conditions and rules to prevent the Covid-19.
|
| Strategy for Future Research Activity |
1) This year, I will further study the reaction mechanisms of MASnI3 and FAPbI3.
2) This year, I am planning to attend conferences to report our recent results.
