Sekisui Chemical has decided to begin mass production of perovskite solar cells. The company has been working to develop and establish mass production technology for lightweight and flexible perovskite solar cells utilizing the Green Innovation Fund, aiming to commercialize the technology in 2025. 

Although the company has established a certain level of technology and plans to commercialize the product in 2025 by manufacturing at its existing facilities, expanding production capacity and reducing manufacturing costs were the issue. 

On December 25, 2024, Sekisui Chemical was selected for the GX Supply Chain Construction Support Project by the Ministry of Economy, Trade and Industry. The company would like to play a central role in realizing the government's goal of establishing a gigawatt (GW) level supply system by 2030, and has therefore decided to make a capital investment with the aim of starting operation of a 100 MW manufacturing line in 2027. 

Sekisui Chemical will continue to invest in the construction of a GW-level production line by 2030, with an eye toward overseas expansion, as it continues to capture demand and gradually increase its investment.
