External Light Source Optics Could Turn Micro TECs Into Multi-Hundred-Million-Dollar Market

Analysts estimate that TECs used in external light source (ELS) optical modules will grow from about 0.2M units in 2026 to 6-10M in 2027, potentially becoming a multi-hundred-million-dollar market by 2028. Tellurium capacity is almost entirely locked up by First Solar.
