CdTe

In thin film photovoltaics, solar panels based on Cadmium Telluride (CdTe) have rapidly been gaining popularity. The manufacturing process requires several thermal processing steps, including heat treatment under chlorine-containing species and annealing of the electrical contact. BTU leverages its experience with large-scale, in-line thermal processing systems. These systems can be well over 100 feet in length and include specialized features like novel atmospheres. BTU has the operational and engineering expertise to produce furnaces of such size and complexity in volume. BTU’s Perseas™ platform for CdTe processing is available in configurations for the contact formation and chlorine anneal applications. The system design is scalable and systems are being offered for R&D, pilot, and production-sized applications.
