5-800mm solar panel quartz plate is a special glass material with high purity, high transmittance, high temperature resistance, and corrosion resistance, widely used in the solar photovoltaic industry. This product is made of high-quality quartz sand (SiO ₂ ≥ 99.99%), which has excellent ultraviolet transmittance (>90%) and thermal stability (can withstand high temperatures of 1200 ℃). It is one of the key components in the manufacturing process of solar panels.  

Product Features

High transparency: high transmittance of ultraviolet and visible light, improving the photoelectric conversion efficiency of solar cells.  

High temperature resistance: It can work in high temperature environments for a long time without deformation or cracking.  

Corrosion resistance: acid and alkali resistant, weather resistant, suitable for various harsh environments.  

High purity: low impurity content, reducing pollution to solar cells.  

Flexible size: Supports customization of different diameters and thicknesses from 5mm to 800mm.

Frequently Asked Questions (FAQ)

Q1: What level of purity do your quartz plates achieve? How does this affect solar cell manufacturing?

A1: The photovoltaic-grade quartz plates we supply have a silicon dioxide (SiO₂) content of 99.99% or higher. During high-temperature processes in solar cell manufacturing—such as diffusion and coating—extremely low impurity levels (especially alkali metals) effectively prevent contamination of the silicon plates. This is the cornerstone for ensuring the photovoltaic conversion efficiency and reliability of the cells. High purity translates to fewer defects and higher power generation efficiency.

Q2: With such a wide size range from 5 to 800 mm, can you guarantee processing precision for every specification?

A2: Absolutely. We operate an integrated production line that spans from continuous pulling of large-size quartz plates to precision slicing, grinding, and polishing. Whether it’s an ultra-small 5-mm window plate or a large 800-mm thermal insulation shield, we strictly control dimensional tolerances, flatness, parallelism, and edge finishing according to your drawings to meet the stringent requirements of precision equipment for components.

Q3: How long can quartz plates operate stably in the high-temperature environment of a photovoltaic production line?

A3: Quartz glass has an extremely low coefficient of thermal expansion (approximately 5.5×10⁻⁷/°C) and excellent thermal shock resistance, enabling it to withstand sudden, drastic temperature changes without cracking. As long as it is used properly within the material’s maximum temperature tolerance range and direct contact with alkaline substances is avoided, its service life is among the best in its class, significantly reducing production line downtime and maintenance costs caused by frequent component replacements.

Q4: In addition to transparent quartz sheets, can you provide milky white or other products for special applications?

A4: Yes. We not only offer transparent quartz sheets with high light transmittance but also supply milky white quartz sheets with specific reflectance and light-blocking properties. For different process stages—such as heat-reflective barriers—we can provide the most suitable combination of optical and thermal performance solutions.

Application

Quartz chips play an important role in the manufacturing of solar panels and are mainly used in the following scenarios:

1. Photovoltaic cell protective layer

-As a covering material for solar cells, it prevents the battery from being affected by environmental factors such as ultraviolet rays, moisture, dust, etc., and extends its service life.  

-Improve light absorption rate, reduce reflection loss, and optimize power generation efficiency.  

2. Solar collector components

-Used as a protective layer for mirrors or lenses in concentrated solar power (CSP) systems to improve heat collection efficiency.  

-The high temperature resistance makes it suitable for high-power concentrated solar energy systems.  

3. Semiconductor and photovoltaic equipment

-As a substrate or encapsulation material in thin-film solar cells such as CdTe and CIGS.  

-Suitable for manufacturing processes of high-efficiency solar cells such as PERC and HJT.  

4. Research and laboratory applications

-Used for solar simulators, optical experimental equipment, etc., to ensure high-precision optical performance.
