TCL Zhonghuan Renewable Energy Technology (TCL TZE), a Chinese solar PV manufacturer, has announced plans to acquire a controlling stake in DAS Solar, also known as Yidao New Energy, an n-type TOPCon solar cell and module maker. The two companies have signed a letter of intent, and the agreement is expected to be finalized within 90 days. The acquisition is aimed at strengthening TCL TZE’s vertical integration and improving operational efficiency across the solar value chain.
TCL TZE is a major producer of G12 n-type wafers and is expanding its solar cell and module manufacturing business. Investing in DAS Solar will align technical standards and processes across materials, cells, and modules, significantly shortening research and development cycles for high-efficiency products. The company called the acquisition a strategic move to integrate high-value assets and enhance operational excellence through technology.
Once the deal is complete, TCL TZE and DAS Solar may jointly explore next-generation n-type technologies, including back contact cells and perovskite tandem cells. DAS Solar is also developing TOPCon back contact technology. The acquisition will allow TCL TZE to operate a more closed-loop system, making better use of its production capacity and reducing reliance on external suppliers. The deal also positions the company to transition from a materials supplier to a comprehensive green energy solutions provider.
As of June 2025, TCL TZE had 200 GW of silicon wafer production capacity and 24 GW of module capacity. The company has previously expressed interest in mergers and acquisitions to manage market fluctuations. TCL TZE also holds a majority stake in Singapore-based interdigitated back contact solar manufacturer Maxeon Solar Technologies and owns SunPower Philippines Manufacturing Ltd, showing its focus on global expansion and technological advancement.
The acquisition reflects a broader trend of consolidation in China’s photovoltaic industry, as persistent overcapacity and margin pressure have increased interest in mergers and partnerships. TCL TZE’s integration of DAS Solar is expected to improve product quality, optimize manufacturing, and accelerate innovation in high-efficiency solar technology.
Overall, the deal is a strategic step for TCL TZE to deepen vertical integration, enhance operational efficiency, and explore next-generation solar technologies. With expanded capabilities across wafers, cells, and modules, the company is positioning itself to meet growing renewable energy demand and strengthen its leadership in China’s solar sector.
