Global Brain has invested in Caelux Corporation (Caelux), a pioneer in utilizing perovskites to make solar energy more powerful and cost-effective, through its 31VENTURES Global Innovation Fund II (31VENTURES II, a corporate venture capital fund of Mitsui Fudosan Co., Ltd.).

Caelux’s proprietary technologies improve the performance of any new crystalline silicon module, making solar energy production much more efficient and cost-effective. The company is building a manufacturing facility in Baldwin Park, California, and ramping up to reach 100MW of perovskite-coated glass. The company’s full-release product, “Caelux™ One” will be a major step forward in realizing the industry goal of greater than 30% efficient commercial tandem solar modules while meeting market requirements for durability. The advancements in scalability, efficiency, and reliability will lead to lower installation costs for developers and installers, increased revenue for module makers, and better returns at the project level by delivering more green energy at a lower cost compared to traditional crystalline silicon modules.

Global Brain has decided to invest in Caelux, in recognition of the strong technology it has developed, large market potential for it, and progress Caelux has made in scaling manufacturing capabilities. Global Brain is joining a strong investor syndicate - including Reliance Industries, a leading solar power generation business in India. Through this investment, Global Brain and Mitsui Fudosan Co., Ltd. will support Caelux to become a leading company in the next generation solar industry.
