Aiming to “revitalize” Japan with perovskite solar cells. The first public-private council meeting has been held!
Perovskite solar cells are considered the trump card for Japan's revival in the solar cell industry. With the aim of promotion, the Ministry of Economy, Trade and Industry established the “Public-Private Council to Expand the Introduction of Next-Generation Solar Cells and Enhance Industrial Competitiveness” and organized the First meeting on May 9.
Build a public-private integrated system
to become a leading country in the world
The first "Public-Private Council to Expand the Introduction of Next-Generation Solar Cells and Strengthen Industrial Competitiveness" was held on May 29, 2024. Reasons behind its establishment council is a sense of crisis regarding the development of perovskite solar cells. Although perovskite solar cells are a technology originating from Japan, research, development and construction of manufacturing plants are progressing rapidly overseas and competition is expected. fierce in the future. For this reason, the Ministry of Economy, Trade and Industry stated that the public and private sectors need to make concerted efforts to establish mass production technology, improve production systems and create demand.
In addition, documents from the Ministry of Economy, Trade and Industry distributed at the council also contained the following self-recommendation: ``Japan has advanced research and development through cooperation between industry, government and academia, starting with ``Project Sunshine'' and in the early 2000s, Japan became the world leader in the number of solar cells installed , achieving global growth. However, it has fallen behind in steadily procuring silicon as a raw material and building out production systems to meet rapidly growing overseas demand and has lost its ability to compete internationally with energy. Glass-based silicon sun. cells, is now mainstream. During this period, the government continued to support development and achieve results such as achieving the highest conversion efficiency in the world, while also making efforts to build a domestic production system to enhance industrial competitiveness. industry to compete with the world. It is also true that Japan has lagged behind other countries in terms of support.

In these cases, using more solar cells is essential to achieve carbon neutrality by 2050 as set by the Japanese government. However, in recent years, the negative impact of solar cells on the environment and landscape has become a regular issue and there are also problems that seem to be hindering the introduction of more solar cells, such as such as reducing available land area. for large-scale solar power plants.
Perovskite solar cells appear to be able to overcome these challenges. Because it is lightweight and flexible, it can be installed in locations considered difficult to install, such as roofs and walls with low load-carrying capacity. In the future, it is expected that the power generation efficiency per unit area will be improved by combining it with existing silicon solar cells.
Although perovskite solar cells have some challenges to overcome, they promise to help Japan revive its solar cell industry. Supporting their development and diffusion is the ``Public-Private Council to Expand Next-Generation Solar Cell Rollout and Strengthen Industrial Competitiveness.'' We should continue to watch trend.
