May 28 (Thu) Zoom Seminar: "Degradation Mechanisms of Perovskite Solar Cells and Design for Higher Efficiency and Longer Lifespan ~Molecular-Level Material Evaluation by Electron Spin Resonance (ESR) Method~"

AndTech Inc. (Headquarters: Kawasaki, Kanagawa; CEO: Masao Suyama), as part of its R&D support services, will host a lecture explaining the "ESR analysis method" and "achieving higher efficiency and longer lifespan" for "perovskite solar cells".

Introducing ESR research on perovskite solar cells and explaining its utility for developing organic devices!

This seminar will provide a detailed explanation on improving the performance and lifespan of perovskite solar cells. It will cover the analysis using the highly sensitive and precise Electron Spin Resonance (ESR) method, which allows for material evaluation at a molecular level, thereby gaining insights from a microscopic perspective.

*A recording will be available for those who cannot attend on the day of the event.
