Heterojunction (HJT) solar cell and module manufacturer Grand Sunergy is expanding into the perovskite tandem solar cell module sector and energy storage manufacturing. The company has signed an agreement with the local government of Tieling, Liaoning Province, to build a new energy industrial park with a total investment of RMB 3 billion ($416.67 million).
According to local media, the project will be implemented in 2 phases and will establish a complete industrial chain covering solid-state battery anode and cathode material production and recycling, cell manufacturing, and pack assembly. It will also include R&D and manufacturing of new technologies such as HJT-perovskite tandem cells and advanced equipment for the new energy sector. The project also explores integrated wind–solar–storage application scenarios, aiming to build a green industrial park.
In March 2025, Grand Sunergy’s subsidiary signed a strategic cooperation framework agreement with perovskite maker Phenosolar.
