US-based companies Heliene and Caelux have launched commercial production of a new Hybrid-Tandem solar module. The product integrates Caelux’s perovskite-doped glass with Heliene’s N-type silicon solar cells, achieving a conversion efficiency of up to 27%.

The technology utilizes a tandem design where a perovskite layer is placed over a silicon layer. According to Heliene, this approach increases the conversion efficiency of their existing silicon platforms by up to 20% without requiring new manufacturing infrastructure.

Manufacturing of the new modules is currently underway at Heliene’s facility in Minnesota. The companies have already scheduled initial deliveries for 2027 and are targeting further efficiency improvements of 29% or higher for future generations of the product.

The partnership leverages domestic supply chains to scale production. This development coincides with ongoing efforts in Congress to streamline permitting processes for energy projects, which industry stakeholders argue is critical for reducing the backlog of clean energy investments.
