Nitto Kogyo Selected as Demonstration Field for Next-Generation "Perovskite Solar Cells"

Nitto Kogyo Co., Ltd. (Headquarters: Nagakute City, Aichi Prefecture, President & CEO: Toru Kurono, hereinafter referred to as Nitto Kogyo) is pleased to announce that its proposal for a demonstration project to be conducted at our Seto Factory in fiscal year 2026 has been evaluated and selected as a demonstration field for Aichi Prefecture's "Perovskite Solar Cell Popularization Expansion Project" (※).

Aichi Prefecture aims to achieve carbon neutrality by 2050 and is promoting the popularization of "perovskite solar cells," which can be installed on walls and roofs with low load-bearing capacity, areas where conventional silicon solar cells are difficult to install.

Nitto Kogyo and its group company EM Solutions Co., Ltd. (Headquarters: Chuo-ku, Tokyo, CEO: Takaaki Mano, COO: Yu Sugawara, hereinafter referred to as EM Solutions) support the purpose of this project. Nitto Kogyo will provide its factory facilities as a demonstration field, and EM Solutions will be responsible for the design and construction of electrical equipment, thereby contributing to the expansion of renewable energy adoption.

As members of the "Aichi Perovskite Solar Cell Promotion Council," Nitto Kogyo and EM Solutions will leverage the knowledge gained through this demonstration to help solve issues and establish model cases for the social implementation of "perovskite solar cells."

※ Solar cells using a crystal structure called perovskite, characterized by being lightweight and highly flexible compared to conventional silicon solar cells.

Background and Objectives of this Demonstration

As suitable locations for solar power generation facilities decrease in Japan, the popularization of "perovskite solar cells," which can also be installed on building walls, is expected. There are approximately 1.3 million units (equivalent to the number of contracts) of "high-voltage receiving equipment" installed in factories, commercial facilities, and office buildings nationwide. This demonstration will verify the effectiveness of this "high-voltage receiving equipment" based on the hypothesis that it has high potential as an installation site.

Demonstration Overview

Perovskite solar cells will be installed on the top and door surfaces of the high-voltage receiving equipment within Nitto Kogyo's Seto Factory and utilized as a power source for surrounding equipment.

Location

Nitto Kogyo Seto Factory (22-4 Yatsuka-cho, Seto City, Aichi Prefecture)

Demonstration Period

Approximately from November 2026 (planned for about 2-3 years)

Demonstration Scale

Approximately 1 kW

Main Verification Items

Measurement of power generation, observation of aging, etc.

Demonstration Theme

・Identification of issues with perovskite solar cells and interconnected distribution systems and establishment of countermeasures

・Establishment of efficient energy management for perovskite solar cells

・Identification of issues in electrical design and construction utilizing perovskite solar cells and establishment of countermeasures
