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.
| Parameter | Specification |
|---|---|
| Test Object | Monocrystalline/polycrystalline cells & wafers (max size: 210×210mm) |
| Detection Speed | <0.5 seconds per test |
| Defect Types Identified | Black center, cracks, low-efficiency cells, hidden cracks, missing corners, etc. |
| Laser System | Adjustable power; 220×220mm laser spot coverage |
| Software | AI algorithms for automatic defect classification; parameterized judgment criteria |
| Integration | Standalone or embedded in production lines via network communication |
| Detection Method | Non-contact PL Testing to prevent secondary damage |
| Compatibility | Pre/post-welding stages; multi-cell simultaneous detection |
AI-Driven Defect Recognition:
Deep learning algorithms automate defect identification (e.g., cracks, black edges) without manual intervention.
High-Speed PL Testing:
Achieves <0.5s detection cycles, ideal for high-volume Solar Cell Testing workflows.
Flexible Integration:
Functions as a standalone Manual Solar Cell Tester or in-line Solar Cell Sorting Machine within production lines.
Customizable Detection:
Adjustable laser power and defect thresholds to adapt to diverse cell types (mono/polycrystalline).
Non-Contact Precision:
Infrared imaging system eliminates physical contact, ensuring zero cell damage.
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.
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.
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).
