Homogeneous color and coating are a prerequisite for homogeneous modules.

Color and defect inspection with COL-Q immediately after the coating process ensures fast intervention in the case of color deviations. CELL-Q checks the color and coating quality during the final inspection and sorts the cells into different performance classes based on their optical properties.

Flawless plating improves conductivity and increases the efficiency of the solar cell. 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.

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. 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. Additionally, CELL-Q identifies visible surface and contour defects to ensure that only homogeneous cells regarding color and performance are processed within one module.

Strings are the backbone of solar modules, and ensuring their quality is paramount. Photoluminescence (PL) inspection for the stringer ensures that only high-quality strings make it into the final assembly.

This cutting-edge technique employs the power of light to uncover imperfections and elevate the quality of photovoltaic strings.

At its core, PL inspection involves illuminating the cells with specific wavelengths of light, stimulating the emission of photons. This emitted light, when carefully analyzed, provides critical information about the string's material integrity and electrical characteristics. ISRA VISION’s PL inspection system LUMI-Q Scan runs laser-free, which reduces safety requirements.

To be an industry leader in the production of photovoltaic cells, companies must offer more than impeccable product quality: Perfectly coordinated processes across systems, production lines, and factories are the basis for maximum profitability, reliability, and short downtimes.

To achieve this, we have developed Connected Photovoltaics 4.0. This cloud-based software solution connects inspection systems, enabling consistent quality settings across all production facilities. It creates transparency, improves process control, and increases the profitability of PV production sites.

With its software features, Connected PV 4.0 meets the key challenges of PV manufacturing.
