Japan launches R&D call for tandem perovskite solar cell mass production
Summary
Japan’s New Energy and Industrial Technology Development Organization (NEDO) is accepting proposals for a six-year R&D program to advance large-scale manufacturing technologies and field testing of next-generation tandem perovskite solar cells.

The program will support research and development of mass production technologies for next-generation tandem perovskite solar cells.</p>
<p>The six-year effort, running from fiscal 2025 to 2030, aims to accelerate commercialization of tandem devices by tackling performance losses during scaling and establishing high-yield, high-throughput production processes. Demonstration tests will also be carried out under real-world conditions, including rooftop and ground-mounted systems, to verify power generation performance.</p>
<p>Applicants may include companies, universities and research institutions. Proposals must be submitted online between Oct. 3 and Nov. 17. Paper submissions, postal mail, fax and email will not be accepted.</p>
<p>NEDO said it will hold an online briefing session on Oct. 10. Participation is not mandatory, but recommended. Applications require registration with Japan’s cross-ministerial R&D management system, e-Rad.</p>
<p>The program is part of NEDO’s Green Innovation Fund, which seeks to reduce power generation costs through technology development and social implementation.</p>
<p>In September, NEDO outlined 24 research themes for a 2025-29 program to advance <a href="https://www.pv-magazine.com/2025/09/12/nedo-outlines-rd-concepts-to-expand-solar-adoption-in-japan/" rel="noopener" target="_blank">next-generation solar cells</a>, system integration, grid stability, and recycling. Earlier this year, the energy R&D agency also published a <a href="https://www.pv-magazine.com/2025/03/31/japans-energy-rd-agency-unveils-solar-strategy/" rel="noopener" target="_blank">solar strategy</a> to advance next-generation PV cells, site-specific systems, module recycling, and long-term operational stability, supporting Japan’s goal of carbon neutrality by 2050.</p>
