Customer ServiceConclusions 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.
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.
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.
Ensuring the quality of manufacturing processes is a crucial part of manufacturing photovoltaic (PV) cells with good performance and low cost [1, 2].
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.
Cell sorting at the end of the line is mandatory for high-value modules of homogenous color. 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.
