Key Findings
Aisin, a major automotive parts manufacturer, has initiated the full-scale mass production development of 500mm square perovskite solar modules, a highly anticipated next-generation solar cell technology. This project is supported by Japan’s New Energy and Industrial Technology Development Organization (NEDO) through its ‘Green Innovation Fund Project.’ Aisin’s participation underscores its pivotal role in commercializing perovskite technology and is expected to bolster Japan’s renewable energy industry competitiveness, particularly through establishing manufacturing techniques and conducting extensive demonstrations for large-area modules.
Technical Details
Aisin’s development plan is focused on the following key technological approaches and objectives:
- Large-Area and High Efficiency: Developing 500mm square modules facilitates easier integration into existing solar cell production lines and enhances power generation per unit area.
- Improvement of High-Speed Spray Coating Technology: The core of mass production, this aims to significantly increase production speed while maintaining the uniformity and quality of the perovskite layer, directly leading to reduced manufacturing costs.
- Multi-Location Demonstration Tests: Long-term evaluations at various sites, including Chubu Centrair International Airport, will verify durability, reliability, and power generation performance under real-world conditions. This will provide robust data for future market introduction.
This project aims to overcome stability and durability, two of the greatest challenges for perovskite solar cells, through scalable manufacturing techniques and real-world validation. The development of large-area modules also envisions applications beyond conventional solar farms, including building rooftops and facades, agricultural facilities, and even mobility sectors like automobiles and ships.
Background & Context
The Japanese government is actively promoting the expansion of renewable energy to achieve its 2050 carbon neutrality goal. Within this context, perovskite solar cells are garnering significant expectations for widespread adoption due to characteristics like ‘lightweight, flexible, and low-light power generation,’ which are challenging for conventional silicon solar cells. NEDO’s Green Innovation Fund plays a crucial role in supporting Japanese industries to keep pace with these technological innovations. Aisin’s involvement highlights how its precision manufacturing technology and quality control expertise, honed in automotive parts manufacturing, can be leveraged for perovskite solar cell mass production.
Strategic Significance & Outlook
Aisin’s mass production development of 500mm square perovskite solar modules, backed by NEDO, is a transformative initiative for Japan’s renewable energy industry. The demonstration tests at Chubu Centrair International Airport are particularly critical for assessing long-term reliability under challenging conditions. Successful completion of this project is expected to lead to the widespread adoption of high-performance, low-cost perovskite solar cells in Japan’s infrastructure, significantly contributing to energy self-sufficiency and greenhouse gas emission reduction. By the 2030s, perovskite solar cells could substantially increase their presence in Japan’s energy mix.
