FAQs About Photovoltaic Quartz Glass
Q: How does quartz purity affect solar cell manufacturing performance?
A: Quartz purity directly impacts contamination levels during high-temperature processes. Impurities such as Al, Fe, and Ti can diffuse into silicon wafers, reducing cell efficiency. Using ≥99.995% SiO₂ quartz minimizes metallic contamination and supports higher solar conversion rates.
Q: Why is thermal shock resistance critical for photovoltaic quartz glass components?
A: During processes like diffusion or annealing, quartz glass components are exposed to rapid heating and cooling cycles. Poor thermal shock resistance can lead to cracking or deformation. TOQUARTZ products are engineered to withstand ΔT > 1000°C without structural failure.
Q: How does photovoltaic quartz glass perform in corrosive wet etching environments?
A: Quartz is highly resistant to acids (HF, HCl, HNO₃) and alkalis, making it ideal for wet benches, etching tanks, and waste collection bottles. Its chemical inertness ensures long service life and prevents contamination of wafers during cleaning or texturing.
Q: Can TOQUARTZ provide photovoltaic quartz glass components for both monocrystalline and multicrystalline silicon production?
A: Yes. We supply quartz crucibles, liners, and accessories tailored for both Czochralski (CZ) monocrystalline and directional solidification (DS) multicrystalline processes, with options for different diameters, wall thicknesses, and thermal profiles.
Q: What surface treatments are available for photovoltaic quartz glass parts?
A: Depending on the application, TOQUARTZ offers flame polishing, acid cleaning, and anti-adhesion coatings (e.g., SiO₂ barrier layers) to enhance surface smoothness, reduce particle generation, and prevent silicon sticking in high-temperature environments.
Q: Why is dimensional tolerance important in photovoltaic quartz glass components?
A: Tight dimensional tolerances (±0.1mm or better) are essential for proper sealing, alignment, and thermal uniformity in furnace systems. Poor tolerances can lead to gas leakage, uneven heating, or mechanical stress during operation.
