U.S. PV Supply Chain Deepens: Swift Solar Buys Meyer Burger HJT Assets For $60M+ Tandem Push

California‑based Swift Solar announced the acquisition of core manufacturing assets and the heterojunction (HJT) patent portfolio from Swiss firm Meyer Burger. The deal includes the transfer of Meyer Burger's specialized engineering and senior management teams, accelerating Swift Solar's construction of gigawatt‑scale domestic production capacity in the U.S.

The acquisition establishes a fully vertically integrated silicon‑perovskite tandem technology pathway for Swift Solar. As an efficient silicon cell technology, HJT serves as an ideal bottom cell for tandem modules. By stacking a perovskite layer on top of HJT cells, Swift Solar aims to break the theoretical efficiency limit of conventional silicon cells, which stands at approximately 30%.

Following the transaction, former Meyer Burger CEO Gunter Erfurt and former Global Head of R&D Marcel Koenig will join Swift Solar to lead HJT technology integration. The deal grants Swift Solar the most comprehensive HJT intellectual property (IP) portfolio in the Western Hemisphere, clearing patent barriers for scaled manufacturing and mitigating litigation risks common in thin‑film and high‑efficiency PV-ensuring operational freedom for the company.

Swift Solar has raised over $60 million from investors and U.S. government agencies including the Department of Energy (DOE) and Department of Defense (DOD). It will deploy capital in three phases toward commercialization:

HJT Expansion: Construct a gigawatt‑scale HJT cell and module factory in the U.S. to meet immediate domestic demand for silicon‑based cells.

Tandem Integration: Integrate Swift Solar's proprietary perovskite technology into established HJT production lines to manufacture two‑terminal tandem cells.

Efficiency Leap: Deliver a 40% increase in power generation compared to conventional modules (20%–24% efficiency) via tandem structures.
