Challenges in Solar Cell Color Inspection

Material Texture and Surface Reflectivity

Variations in texture and reflectivity across solar cells can lead to inconsistent light absorption, making it difficult to detect subtle color differences that may indicate defects or irregularities.

Subtle Color Variations

Minor color changes, often caused by coatings or electrode inconsistencies, are hard to identify using traditional visual inspection methods. These undetected defects can progress into production, causing costly quality issues.

Uneven Lighting Conditions

Inconsistent lighting across inspection environments or panel orientations can skew color detection results, reducing accuracy and making it challenging to maintain reliable quality control.

Manufacturing Inconsistencies

Variations in manufacturing processes, including coatings and layering, can result in color inconsistencies that complicate inspections without precise, high-resolution imaging and intelligent vision algorithms.
