Solar Cell Ultra-clean Workshop Quality Inspection

Why is quality control important for solar cells?

Careful quality control and monitoring are essential to ensure solar cells are uniformly plated. Manufacturers must quickly identify inhomogeneities, surface adhesion problems, and contaminations before affecting quality. This ensures high durability and prevents efficiency loss.

How does cell-q inline inspection work?

The CELL-Q inline inspection system checks the front or back of solar cells and sorts them into different color and quality classes according to their optical properties. In a single inspection step, CELL-Q checks every solar cell's print quality and anti-reflection coating.

Can a quality inspection system detect defects in monocrystalline solar cells?

Conclusions In this work, an anomaly detection-based methodology has been proposed for the development of a quality inspection system of monocrystalline solar cells. With anomaly detection, only defect-free samples are required to obtain a model for inspection which can detect and locate defects in the cells.

How does cell-Q check a solar cell's print quality?

In a single inspection step, CELL-Q checks every solar cell's print quality and anti-reflection coating. Any print and color defects on all cell technologies are reliably detected.

How GP solar optical inspection systems improve efficiency & performance?

Precise alignment across the entire solar cell enhances efficiency and performance. Optical inspection systems from ISRA VISION / GP Solar inspect the alignment across the entire cell and even detect local deviations . The systems use a flexible lighting concept to maximize the visibility of contrasts between the layers.

Can DL methods be used in solar cell inspection?

In more recent works, DL methods have been widely applied in the solar cell inspection field. These methods can directly extract meaningful features from the raw data without any feature engineering work, thus making these methods more flexible to changes.
