News release

HighChem Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and CEO: Ushio Taka) has successfully developed and commenced the provision of its proprietary material, "Spiro-MeOTAD," designed for the hole transport layer in perovskite solar cells, which are currently capturing widespread attention as the next-generation of solar cells.

What are Japan-made next-generation perovskite solar cells?

Perovskite solar cells represent the cutting edge in next-generation solar technology, boasting an impressive level of conversion efficiency, nearly on par with the well-established silicon solar cells that currently dominate the market. Their distinct advantage lies in their ability to maintain remarkable conversion efficiency even in indoor low-light conditions, and enabling power generation on rainy or cloudy days, a feat that conventional solar cells struggle to achieve. Furthermore, they can make at lower temperatures, facilitating their application on flexible film substrates and paving the way for the development of flexible, foldable solar panels. Perovskite solar cells hold immense potential for deployment as energy sources on building walls, EV rooftops, and as power providers for IoT devices like personal computers and smartphones.

Realized the Goals of "Cost Efficiency" and "Consistent Supply" for Perovskite Solar Cell Materials!

The hole transport material "Spiro-MeOTAD" for perovskite solar cells, developed by HighChem, is positioned to make a significant impact by offering a cost-effective solution for solar cell manufacturing. Moreover, it is designed to ensure a reliable and uninterrupted supply of raw materials, capable of meeting the demands even as perovskite solar cell production scales up. Additionally, it exhibits compatibility with high-purity materials (purity exceeding 99.5%) due to the company's proprietary technology.

Presently, HighChem has established a production infrastructure for small-scale output at its Tokyo Research Institute and has officially commenced product availability. Furthermore, a production facility in collaboration with factories is currently in the process of development, thereby enabling mass production capabilities all over the world, effectively catering to the needs and preferences of customers.
