"Perovskite semiconductors" developed by Kojima Laboratory were exhibited at Osaka Science Museum

Perovskite semiconductors for optical cooling" developed by our laboratory will be on permanent display at the Osaka Science Museum from July 4, 2025. The actual perovskite semiconductor is displayed as an example of the use of cesium in the “Utilization of Elements” section, which introduces products containing each element. If you are in the neighborhood, please stop by.

【Comment from Naoki Nobuo, Research Manager】
Our research team is developing light-cooled semiconductors (perovskite semiconductors) with the goal of lowering temperature with light (optical cooling). Please take a look at these crystals, which have a very unique property of absorbing energy when illuminated by light, while at the same time removing heat and cooling the material.
The 72nd JSAP Spring Meeting 2025

I participated in the 72nd JSAP Spring Meeting, which was held in Chiba Prefecture from March 14. It was my first external presentation, and I was quite nervous, but I was able to complete my presentation successfully. Through the presentations and discussions, I learned how my research is positioned and gained valuable insights that will guide my future research activities. I was also able to broaden my knowledge by engaging in the latest research findings and studies from other fields. (Tanaka)

On the Departure of a Lab Staff Member
Our secretary, Ms. Hanada, who has supported the Kojima lab since its inception, will be leaving us to pursue a new challenge. Throughout her time with us, she provided support in a wide variety of tasks, and her warm and thoughtful assistance was a great help to all of our members.
We sincerely wish her all the best in her future endeavors.
