The Ideal Solution for Inspection of Photovoltaic Cells and Wafers
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 type of inspection enables you to optimize the 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 characterization of solar cells in the production as well as in research and development.
The LumiSolarCell System
The award-winning LumiSolarCell System utilizes the photoluminescence, electroluminescence, and infrared phenomena to image micro-cracks, shunts, regions of low lifetime, non-homogeneities, 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, 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.
Due to the outstanding sensitivity of the whole set-up, multiple PV technologies, such as Si-based cells and wafers as well as thin-film mini modules, can be measured. LumiSolarCell is delivered as a turnkey system and consists of a highly sensitive, scientific CCD-camera and a high power, LED light source, developed and produced by greateyes. Different versions of the system are available (off-line, automated batch system, OEM in-line, pure PL or EL, combined EL/PL, or EL/PL/IR/Rs). Furthermore the LumiSolarCell system outperforms commercially available PL systems with very short exposure times by using a highly sensitive CCD-camera and the flexibility to measure a variety of different wafer materials, such as mono-Si, a-Si, CIS, HIT, and many more.
Systems from greateyes provide spatially resolved information on crucial material properties, proving invaluable for both production and R&D.
