What is photovoltaic quartz boat?

Photovoltaic quartz boats (also called quartz carrier, wafer boat) are specialized quartz containers used in the manufacturing process of solar cells. It is designed to hold and support silicon wafers during high-temperature treatments such as diffusion, oxidation, and annealing inside furnace equipment. Made from high-purity fused quartz, these boats can withstand extreme heat without contaminating the wafers, ensuring consistent quality and efficiency in photovoltaic cell production.

Why must quartz be used to make boats for PV?

Because it has excellent high-temperature resistance and thermal stability, which allows it to withstand the extreme heat of solar cell processing without deforming. Its low thermal expansion minimizes cracking during rapid heating and cooling. Additionally, quartz is chemically inert and ultra-pure, preventing contamination of silicon wafers and ensuring high solar cell efficiency. These properties make quartz boats essential for reliably supporting wafers during critical high-temperature steps.

How to judge a high-quality quartz boat for PV?

Find a high-quality photovoltaic quartz boat, focus on these key points:

1. High purity to prevent contamination

2. Smooth surface with no cracks or defects

3. Accurate dimensions for stable wafer placement

4. Strong thermal shock resistance to handle rapid temperature changes

5. Good mechanical strength at high temperatures to avoid deformation
