High-Purity Quartz Glass for Solar & Photovoltaics Manufacturing
Engineered for ultimate purity in silicon melting, crystal growth, and wafer processing.
The Critical Role of Quartz Glass in Solar Cell Production
In the photovoltaic (PV) industry, the efficiency of a solar cell is directly tied to the purity of its silicon crystal. For this reason, high-purity quartz glass stands as the essential material for the foundational stages of solar manufacturing, especially in the Czochralski (CZ) crystal growth method.
Its unmatched purity and high-temperature stability provide a completely inert environment for melting polysilicon above 1450°C. As a result, it prevents the introduction of impurities that would degrade electrical performance, ensuring a higher quality ingot and leading to more efficient solar wafers.
Applications of Our Quartz Glass in PV Manufacturing
Our quartz components are engineered for maximum purity and stability in every step of solar wafer production.
Silicon Melting & Crystal Growth
Our high-purity Custom Quartz Glass Crucibles provide the industry-standard inert vessel required to melt polysilicon and pull a monocrystalline ingot during the Czochralski (CZ) process.
Wafer Handling & Processing
Furthermore, our precision Quartz Glass Boats and carriers safely handle and transport thin silicon wafers through various wet chemical etching, cleaning, and texturing processes.
Diffusion & Doping Furnaces
Large-diameter Quartz Glass Tubes create the process chamber for high-temperature diffusion, where phosphorus or boron is introduced to create the critical p-n junction in the solar cell.
Anti-Reflective Coating (PECVD)
In addition, PECVD reactors utilize our Custom Quartz Glass parts like showerheads and liners for depositing silicon nitride (SiN) anti-reflective coatings, thereby maximizing light absorption.
