en.Wedoany.com Reported - Kyocera Communication Systems Co., Ltd. (KCCS) is testing perovskite solar module technology developed by Sekisui Chemical Co., Ltd., with pilot projects installed at six KCCS facilities in Fukuoka and Shiga prefectures. KCCS is a technology and engineering subsidiary of Japan's Kyocera Group. The company stated that these projects are supported by Japan's Ministry of the Environment and two prefectural governments.
The company noted that in recent years, the adoption of renewable energy has accelerated to achieve a decarbonized society, but the limited availability of sites suitable for solar power installations has become an increasingly serious challenge. Thin-film perovskite solar cells, being lightweight and flexible, can be installed in locations where traditional silicon-based solar panels are difficult to use due to load-bearing constraints, making them a promising solution to this issue.
Sekisui Chemical announced last year the launch of a 100 MW production line for perovskite solar cells. Subsequently, the company partnered with MUFG Bank (a subsidiary of Mitsubishi UFJ Financial Group) to conduct two perovskite panel demonstrations at two locations owned by the bank. Sekisui Chemical is also undertaking projects with multiple partners at various sites across Japan under different weather conditions and configuration requirements, including agrivoltaics, and is collaborating with the Slovak Ministry of Economy on perovskite solar cell technology.
In its announcement, Sekisui Chemical reiterated that it is developing a new 30 cm wide roll-to-roll manufacturing process for producing perovskite solar panels, with an initial power generation efficiency of 15.0% and outdoor durability equivalent to 10 years. The company also plans to improve durability and power generation efficiency, and expand the width to 1 meter. In late November 2025, Japan's Ministry of Economy, Trade and Industry (METI) stated its plan to deploy approximately 20 GW of new photovoltaic systems based on perovskite solar cell technology by 2040.
