The LIS is BTi's patent protected enabling technology. The LIS enables high resolution Luminescence images of PV samples to be acquired on the order of a second. The LIS is the cornerstone of BTi's R&D and Manufacturing products.
Advantages of PL imaging using BTi’s LIS:
- Contactless, no sample preparation needed
- Fast
- High spatial resolution
- Robust against various artifacts (e.g. Trapping and DRM)
The LIS is compatible with Silicon Blocks, as cut wafers, passivated wafers, partially and fully processed solar cells.
