Solar Cell Inspection
Highly sensitive inspection systems for solar cells
Processed wafers and solar cells suffer from a variety of invisible defects which reduce their output power and long-term stability. The highly sensitive inspection systems from greateyes image these problems. This allows you to optimise production, increase output power, and reduce overall costs.
Furthermore greateyes inspection systems integrate a variety of different inspection methods in a compact, safe, and low-maintenance device. They are used for detailed characterisation of solar cells in the production as well as in research and development.
LumiSolarCell - innovative, award winning system
The award-winning LumiSolarCell System utilises the photoluminescence, electroluminescence, and infrared phenomena to image micro cracks, shunts, regions of low lifetime, inhomogeneities, hot spots, or other cell failures of photovoltaic cells or wafers.
EL, PL, and IR as contactless, and therefore non-destructive, methods are an indispensable tool for advanced solar research. In addition to that, the series resistance (Rs) can be measured by an algorithm which compares EL images taken under low and high current conditions. The knowledge gained will lead to increased product quality and yield.
Different versions of the LumiSolarCell system are available:
- Pure EL
- Pure PL
- Combined EL PL with the option to add IR and dark-lock-in thermography or Series Resitant (Rs) measurements
We also offer off-line, automated batch system, and OEM in-line options – please get in touch to discuss your specific requirements.

LumiSolarCell software
Providing camera control and data set visualisation
The LumiSolarCell software controls the camera and visualizes the data sets. The program can generate intensity profiles from the 16-bit high dynamic range image data. Basic picture manipulation procedures are included in the software. Dimension measurements of artefacts are possible following calibration as well as remote control of power supply and high power LED light source.
