Key Features
Light Engine Features:
The light engine consists of LEDs with 24 different peak wavelengths. A special optical lens system ensures perfect color mixing for each spot on the solar cell. Built-in spectrometer and intensity sensor in combination with calibration routine make re-calibration very simple.
| Light source |
19 individually controlled LED channels to create the desired spectrum |
| SPD |
≤ 21% |
| SPC |
≥ 98% |
| Ready for tandem cells |
Additional LEDs between 600 – 800 nm for probing the SR transition of the top and bottom cell (e.g., Si-Pero tandem cells) |
| Special optical lens system |
The multi-level special optical lens system ensures perfect mixing of all wavelengths, illuminating each spot with the identical spectrum |
| Feedback system |
Built-in intensity sensor measures total intensity multiple times per measurement, with on-the-fly adjustments |
| Spectrum |
AM1.5g, AM0, or customer-defined spectrum including single LED channel irradiation |
| Spectral control |
Built-in spectrometer monitors current spectrum for any flash length, displayed on GUI |
| Intensity range for AM1.5g |
Qualified intensities: 0.5, 1.0, 1.3 suns; intermediate intensities can be set individually |
| Intensity range for each single LED channel |
Adjustable from 10% up to 100% |
| Irradiance time |
Adjustable from 10 ms up to 250 ms |
| Test area |
260 mm x 260 mm (non-uniformity <1%) |
| Cooling |
Air-cooling for high stability and large lifespan |
| Expected LED box life span |
More than 2 years under standard inline operating conditions |
I-V Electronics Features:
The very fast active electronic load allows 4 quadrant measurements. A 14-bit calibrated Analog-Digital converter and calibrated, traceable shunt resistor fulfill the highest demands for accuracy and precision.
