Solar Cell Sorting & PL Testing System (Model: YHCT-PL)

Functionality:
A cutting-edge Solar Cell Tester integrating PL Testing (photoluminescence detection) and AI-driven defect recognition for Solar Cell Testing and sorting. Designed for monocrystalline/polycrystalline silicon wafers and cells, it enables non-contact, high-speed quality control in photovoltaic manufacturing.

Technical Specifications

Key Features

1. AI-Driven Defect Recognition:

   • Deep learning algorithms automate defect identification (e.g., cracks, black edges) without manual intervention.

2. High-Speed PL Testing:

   • Achieves <0.5s detection cycles, ideal for high-volume Solar Cell Testing workflows.

3. Flexible Integration:

   • Functions as a standalone Manual Solar Cell Tester or in-line Solar Cell Sorting Machine within production lines.

4. Customizable Detection:

   • Adjustable laser power and defect thresholds to adapt to diverse cell types (mono/polycrystalline).

5. Non-Contact Precision:

   • Infrared imaging system eliminates physical contact, ensuring zero cell damage.

System Components

• Laser Light Source: Generates uniform 220×220mm square spots for consistent PL excitation.

• Infrared Camera & HD Lens: Captures high-resolution defect images without darkroom requirements.

• Detection Software: User-friendly interface with real-time analytics and customizable reporting.

Applications

• Quality Control: Defect detection in raw wafers, post-processed cells, and final modules.

• Sorting: Grades cells based on PL Testing results for Solar Cell Sorter integration.

• R&D Support: Identifies efficiency losses and process flaws in cell manufacturing.

Why Choose Our Solar Cell Sorting Machine?

• Zero Secondary Damage: Non-contact PL Testing ensures cell integrity.

• Production-Ready: Seamless integration into existing Solar Cell Testing lines with ≤20ms latency.

• Future-Proof Design: Software upgrades and modular hardware adapt to new cell technologies (e.g., TOPCon, HJT).
