CTIA's Tungsten Heater in Photovoltaic Materials
CTIA’s tungsten heater acts as a resistive heating element to heat and ensure the stable evaporation of metal or compound materials during the vacuum coating and deposition of photovoltaic materials such as solar cell components and thin films. Produced from high-purity tungsten wire through precision stranding, coiling, and surface treatment, tungsten heater is utilized in Physical Vapor Deposition (PVD) or thermal evaporation processes. The component forms electrode layers, anti-reflective coatings, and functional structural layers on silicon wafers or thin-film substrates, supporting both the metallization of crystalline silicon cells and the formation of absorption layers for Cadmium Telluride (CdTe) and Copper Indium Gallium Selenide (CIGS) thin-film batteries.
Features of CTIA’s tungsten heater in Photovoltaic Applications
Photovoltaic conversion efficiency depends heavily on the purity and uniformity of thin-film deposition. CTIA’s tungsten heater meets these rigorous requirements through several key performance features:
(1) Ultra-high temperature capability: Tungsten heater provides a stable heat source during high-temperature evaporation, as tungsten has a melting point of 3410°C and maintains structural integrity during continuous operation.
(2) Low contamination: Low vapor pressure under high vacuum minimizes self-volatilization and metal impurity contamination, improving film purity.
(3) Thermal field uniformity: Optimized coil structures and resistance matching enable a stable heat radiation distribution, which is essential for controlling consistent film thickness.
(4) Structural stability: Refined grain and doping structures allow tungsten heater to maintain its shape during frequent thermal cycles, reducing deformation risks and extending the service life.
