U.S. perovskite solar developer Tandem PV has acquired nexTC, an Oregon-based startup that specializes in advanced thin-film metal oxide coating processes, in a move designed to bring a critical manufacturing step under direct company control.

Strategic Integration of Coating Technology

The deal incorporates nexTC's coating technology, intellectual property, and technical expertise into Tandem PV's operations. Thin-film metal oxide coatings represent a key process step in the production of tandem solar modules, which pair perovskite layers with conventional silicon cells to achieve higher theoretical efficiencies than either material alone. By acquiring nexTC outright rather than licensing or sourcing the technology externally, Tandem PV gains tighter oversight of that process as it works toward commercial-scale output.

Demonstration Line and Production Readiness

Tandem PV is currently ramping a perovskite-silicon demonstration line in California. The acquisition is intended to support that effort and position the company for broader commercial production. Bringing nexTC's capabilities in-house gives Tandem PV more direct control over coating process development and quality at a stage when manufacturing consistency is considered essential for proving the viability of perovskite-based modules at scale.

Context for the Perovskite Sector

Perovskite and perovskite-silicon tandem solar technologies have attracted significant industry and investor attention due to their potential efficiency advantages over conventional crystalline silicon panels. However, the path from laboratory performance to durable, manufacturable products has required intensive process engineering work across multiple production steps, including the precise application of functional thin-film coatings. Acquisitions of specialized process developers like nexTC reflect a broader pattern among emerging solar manufacturers seeking to consolidate supply chain control and proprietary know-how ahead of commercial launch. Tandem PV's move to internalize nexTC's metal oxide coating process follows that logic, reducing reliance on external partners for a step that directly affects module performance and yield.
