The photovoltaic sandblasted quartz boat is engineered to carry silicon wafers during high-temperature processes in PERC (Passivated Emitter and Rear Cell) solar cell manufacturing, including diffusion, oxidation, and annealing. Made from ultra-pure fused silica, it provides excellent thermal stability, corrosion resistance, and minimal impurity levels, ensuring contamination-free wafer processing.

Its sandblasted surface and precise design maintain consistent wafer spacing, promoting uniform gas flow and controlled thermal distribution—key factors for high cell efficiency and production yield. With superior resistance to thermal shock and chemical attack, this quartz boat is ideal for demanding PV furnace environments.

Sandblasted Quartz Boats vs Polished Quartz Boats

In solar photovoltaic (PV) manufacturing, quartz boats are essential for high-temperature processes such as crystal growth and silicon wafer diffusion. Two common types are sandblasted quartz boats and polished quartz boats, each with unique advantages.

Polished quartz boats feature a smooth surface that minimizes particle adhesion and contamination. They are ideal for processes that require clean, uniform heat distribution and high wafer purity.

Sandblasted quartz boats, on the other hand, have a textured surface created through sandblasting. This increases surface roughness, which can improve wafer stability, prevent slipping, and enhance adhesion during certain high-temperature processes. Sandblasted boats are particularly useful when handling wafers that need slight grip or controlled contact with the boat surface.

Choosing between sandblasted and polished quartz boats depends on the specific manufacturing process and product requirements. Polished boats excel in high-purity applications, while sandblasted boats offer better wafer handling and stability. Selecting the right type can significantly impact yield, efficiency, and overall quality in photovoltaic production.
