Chinese PV Industry Brief: DKEM Seeks Cash Injection to Scale up Gigawatt-Level Production of Copper Metallization Paste

Why It Matters

Scaling copper‑based metallization lowers material costs and reduces reliance on scarce silver, accelerating deployment of high‑efficiency TOPCon modules and supporting China’s fast‑growing solar market.

Key Takeaways

• DKEM targets CNY 3 bn ($413 m) private placement.
• Funds support 2,000 t/yr low‑silver paste and 1,450 t/yr metal‑powder projects.
• High‑copper paste moves to volume for TOPCon 3.0 cells.
• Silver price pressure drives shift to copper‑rich metallization.
• Debt repayment of CNY 900 m improves balance sheet.

Pulse Analysis

The photovoltaic industry is at a crossroads where material economics intersect with sustainability goals. Rising silver prices have made traditional high‑efficiency cells increasingly expensive, prompting manufacturers to explore copper‑rich metallization. Copper offers comparable conductivity but historically suffered from oxidation and diffusion challenges. Recent advances in seed‑layer chemistry and paste formulation have mitigated these risks, enabling high‑copper pastes to meet the stringent reliability standards of TOPCon 3.0 cells, a technology poised to push efficiencies beyond 24%.

DKEM’s decision to raise CNY 3 billion reflects both the capital intensity of scaling new material lines and the confidence of investors in a copper‑centric future. The earmarked 2,000 t/yr low‑silver paste plant and 1,450 t/yr metal‑powder upgrade will create a domestic supply chain that reduces dependence on imported silver and aligns with China’s policy push for greener, cost‑effective solar manufacturing. By allocating CNY 900 million to debt repayment, DKEM also strengthens its balance sheet, positioning the firm for further strategic acquisitions or joint ventures in the fast‑moving PV market.

For the broader industry, DKEM’s financing signals a shift toward diversified metallization portfolios. Investors are likely to view copper‑based solutions as a hedge against commodity volatility, while module makers can anticipate lower bill‑of‑materials costs and improved sustainability credentials. As China continues to add gigawatts of solar capacity each quarter, the adoption of high‑copper pastes could accelerate the rollout of TOPCon modules, reshaping global supply dynamics and setting new benchmarks for efficiency and cost in the renewable energy sector.
