NEDO has unveiled a solar PV technology-focused strategy to help Japan achieve carbon neutrality by 2050
It focuses on next-generation solar cells, improved installations, diverse applications, efficient maintenance, and recycling efforts
NEDO says this strategy aligns with the country’s 7th Basic Energy Plan, approved by the cabinet recently
Japan’s state-owned energy R&D agency, the New Energy and Industrial Technology Development Organization (NEDO), has unveiled a solar PV power generation development strategy with an aim to reach carbon neutrality by 2050.
Named NEDO PV Challenges 2025, the strategy identifies challenges related to the development of solar power generation in Japan as well as overseas. To address these, it presents the following 5 technical measures:
Development of next-generation solar cells, such as perovskite, tandem cells, and III-V compound cells.
Development of solar power generation systems to expand their adoption, including the installation and construction methods for flexible solar cells.
Address diverse market requirements with demonstration tests for vehicle-integrated solar, building-integrated, for application on windows to promote their installation.
Development of efficient and effective O&M technologies for long-term stable operations and the development of highly accurate solar radiation prediction technology.
Development of a circular recycling system for solar PV systems, including perovskite solar cells, bifacial solar cell modules, etc.
This plan supports the country’s 7th Basic Energy Plan recently approved by the Japanese cabinet, wherein it will target to achieve up to 50% renewable energy share by FY2040. Solar is the key focus technology under this plan (see Japan To Aim For 20 GW Perovskite Solar Cell Capacity By 2040).
NEDO said that it will launch a call for proposals for solar power generation projects, based on this strategy, in mid-April 2025.
