H.I.S., Saule, and Lawson Are Starting The First Trials Of Perovskite Solar Cells Within Japan’s Retail Chain
H.I.S., Saule Technologies, and Lawson are piloting perovskite solar technology in Tokyo to innovate retail energy solutions.
- H.I.S., Saule Technologies, and Lawson are testing film-based perovskite solar cells at the Green Lawson store in Tokyo, starting December 16, 2024.
- The solar cells power electronic shelf labels and electronic paper, enabling remote content updates.
- Perovskite panels installed on interior walls generate energy for in-store displays.
- The project promotes innovative and sustainable solutions for the retail industry.
Monday, December 16, 2024, H.I.S. Co., Ltd. joined forces with Saule Technologies and Lawson, Inc. – large chain of retail grocery stores based in Japan – to launch a pilot program at “Green Lawson” in Tokyo. This initiative will test the use of film-based perovskite solar cells, a cutting-edge energy solution, within the store environment.

Key Pilot Features
Electronic Shelf Labels
Traditional batteries have been replaced with perovskite solar cells that generate electricity from indoor lighting. This sustainable solution powers remote updates for product details and pricing, streamlining operations.
Electronic Paper
Electronic paper replaces conventional in-store paper ads, displaying dynamic information. Powered by perovskite solar cells, these digital signs can be updated remotely, reducing waste and improving efficiency.
Interior Power Generation Panels
Panels featuring perovskite solar technology are mounted on the store’s interior walls. These panels generate electricity for powering electronic paper displays, enhancing the store’s energy independence.
About the Store
Store Name: Green Lawson (Lawson Kita-Otsuka 1-chome)
Location: 1-13-4 Kita-Otsuka, Toshima-ku, Tokyo
