First Tellurium Corp. announced that its subsidiary, PyroDelta Energy, is developing a tellurium-based thermoelectric film designed to extend electricity generation from solar panels beyond daylight hours and during low sunlight.

The film applies to the back of conventional photovoltaic panels without altering their design, operating by capturing energy from temperature differentials between the panel and its environment.

“Our objective is not to replace photovoltaic generation, but to complement it by capturing energy from temperature differentials when solar irradiance is low or unavailable.”

— Michael Abdelmaseh, Head Engineer

The subsidiary also advanced international patent filings for its clean energy and capillary casting technologies in Canada, China, Europe, Japan, South Korea, and the United States on September 8, 2026. In addition, PyroDelta developed a next-generation heavy-lift unmanned aerial vehicle designed to carry a 300-pound payload, with flight tests scheduled for September 2026.

First Tellurium President and CEO Tyrone Docherty noted that the solar initiative runs alongside the subsidiary's primary commercialisation efforts.

“Our immediate focus remains the drone technology, which we believe represents the most direct path to commercialization and an important opportunity to demonstrate the broader potential of our thermoelectric technology. As we establish markets for the drones, we intend to advance other applications, including solar.”

— Tyrone Docherty, President and CEO

PyroDelta's solar film remains at an early stage of development.
