Japan-based Sekisui Chemical was established in 1947 and consists of three division companies (entities) and a corporate department. Sekisui is involved in a wide range of business in industries like: real-estate and housing, electronics, automotive, various chemicals and plastics (like photosensitive materials, semiconductors and more) and more.
In the field of perovskites, Sekisui seems to be involved in research pertaining to aspects of solar cells like encapsulation and coatings, stability improvements and more. The Company may be working with Panasonic, but this is not confirmed.
In 2023, Sekisui announced it will begin mass production of perovskite solar cells, in an effort to catch up with Chinese competitors.

Researchers examine the importance of barrier films in maintaining the long-term durability and stability of flexible PSC modules
Researchers from Japan's Ritsumeikan University and Sekisui Chemical have studied the role of barrier films in shielding flexible perovskite solar modules from harsh environmental conditions.
The research team utilized PSC modules made of methylammonium lead iodide (MAPbI₃), which were encapsulated with polyethylene terephthalate substrate with barrier films of varying water vapor transmission rates (WVTR). The PSC modules were subjected to a damp heat test, which utilized exposure of the modules to 85 °C temperature and 85% relative humidity. The conditions were set to simulate real-world outdoor conditions over extended periods.
Sekisui Chemical and Bank of Mitsubishi UFJ launch two pilot perovskite PV projects in Japan
According to reports, Sekisui Chemical, which recently invested in a 100 MW perovskite solar production plant, has announced its latest demonstration project at two sites owned by Japan’s MUFG Bank, a subsidiary of Mitsubishi UFJ Financial Group. The project aims to both raise awareness of practical applications of perovskite solar PV technology and to further verify durability, weather resistance, and performance.
It seems that the project includes two installations, one located at MUFG Bank Oi Branch, Shinagawa-ku, Tokyo, featuring perovskite solar panels installed behind window panes at the entrance to power an outdoor display notice board, and a second site - a rooftop installation at MUFG Global Learning Center in Nishi-ku, Yokohama City where perovskite modules are installed alongside conventional silicon solar panels.
JR Tokai to mount perovskite solar cells on bullet train noise barriers
Central Japan Railway Co. (JR Tokai), which operates the Tokaido Shinkansen Line, has announced plans to install perovskite solar cells on noise barriers along its tracks. The company expects to use electricity generated by these cells to power lighting at stations and other rail-related facilities. The noise barriers will cover about 650 kilometers of track.
Demonstration experiments will start at a research center in Komaki, Aichi Prefecture, and elsewhere this month, using perovskite solar cells jointly developed with Sekisui Chemical.
Sekisui Chemical plans 100 MW perovskite solar production line as part of move for commercialization
Sekisui Chemical has announced it was selected for the GX Supply Chain Construction Support Project by Japan's Ministry of Economy, Trade and Industry. The company would like to play a central role in realizing the government's goal of establishing a gigawatt (GW) level supply system by 2030, and has therefore decided to make a capital investment with the aim of starting operation of a 100 MW manufacturing line in 2027, for producing lightweight perovskite solar panels, to be used initially for low load-bearing rooftops.
The Company plans to take over the buildings of Sharp Corporation in Sakai City, Osaka Prefecture, and install perovskite solar cell manufacturing facilities to carry out manufacture and sales.
Japanese Government to fund perovskite solar cell demonstration project
It was reported that Japan's Ministry of Economy, Trade and Industry (METI) and the New Energy and Industrial Technology Development Organization (NEDO) have decided to support a demonstration project for perovskite solar cells conducted by Sekisui Chemical and Tokyo Electric Power Company Holdings (HD).
The total project cost is estimated at about 18.3 billion yen ( just under USD$119,000,000), with approximately 12.5 billion yen (around USD$81 million) to be subsidized through the Green Innovation (GI) Fund project. The project will verify installation methods, construction methods, and mass production technologies that take advantage of the unique characteristics of perovskite solar cells.
