California-based solar innovator Tandem PV has announced its acquisition of nexTC Corp., a specialist in thin-film metal oxide coatings. This strategic move aims to vertically integrate a critical technology, enhancing the efficiency and durability of Tandem PV's perovskite-silicon solar panels. The acquisition, the financial terms of which were not disclosed, marks a significant step in the company's path toward commercial-scale production.


A Strategic Integration for Manufacturing Control

The primary driver for the acquisition is Tandem PV's goal to gain greater control over its manufacturing supply chain. By bringing nexTC's proprietary coating technology in-house, the company can directly oversee a core component of its panel production. This vertical integration is crucial as Tandem PV prepares to ramp up its manufacturing operations to meet growing market demand.

Direct control over the coating process allows for seamless optimization on the production line, according to company officials. This integration is expected to accelerate innovation cycles and improve the overall quality and consistency of their solar modules. Ultimately, it positions Tandem PV to more effectively scale its advanced technology from demonstration to full commercial availability.

Bolstering Panel Performance and Durability

Headquartered in Oregon, nexTC specializes in developing solution-based transparent oxide coatings for photovoltaic applications. These advanced materials form extremely thin, transparent layers that are essential for modifying charge transport within the solar cell. The technology is designed to maximize light absorption while maintaining the structural integrity of the panel.

The application of nexTC's coatings is set to deliver significant improvements to Tandem PV's product line. The technology is engineered to boost module efficiency, allowing more sunlight to effectively reach the silicon cell below the perovskite layer. Furthermore, these coatings enhance the durability and manufacturability of the panels, contributing to longer lifespans and more streamlined production.

Leadership and Future Outlook

A key aspect of the deal is the integration of talent, with nexTC founder and CEO, Dr. Cory Perkins, joining the Tandem PV team. Tandem PV's CEO, Scott Wharton, highlighted their long-standing professional relationship and the immense value of Dr. Perkins' expertise in oxide thin films. This addition of specialized knowledge is considered a significant asset for the company's future development efforts.

This acquisition closely follows the inauguration of Tandem PV's new 65,000-square-foot commercial demonstration factory in Fremont, California. The facility features a production line with an annual nameplate capacity of approximately 40 MW. It is dedicated to producing large-format tandem solar panels, representing a major step in the company's commercialization strategy.

Dr. Perkins noted his confidence in Tandem PV's proven ability to translate scientific advancements into viable manufacturing processes. He stated that joining the company provides a unique opportunity to integrate nexTC's technology directly into a platform advancing toward commercial scale. This shared vision for innovation and production underscores the synergy between the two organizations.


In conclusion, Tandem PV's acquisition of nexTC represents a calculated and strategic enhancement of its manufacturing capabilities. By internalizing critical coating technology and expert talent, the company strengthens its position in the competitive solar technology landscape. This move not only accelerates its path to commercialization but also signals a strong commitment to producing more efficient and durable solar solutions.
