PSL HE-EL
Load and Measuring Device for High Efficiency cells
PC controlled load simulation and IV curve measurement for high efficiency solar cells includes 1000 W/m², 500 W/m², Dark Reverse and Dark Forward test. Optimized for higher and longer current flow for high class EL-Imaging-Systems
The PSL HE-EL is optimized for fully automated production lines. It records four complete IV curves at 1000 W/m², 500 W/m², Dark Reverse and Dark Forward in one measurement cycle. Using an external power source up to 15 A at 15 V can be supplied for high class El-Imaging-Systems with automatic evaluation on mono and poly crystalline cells (current flow up to 500 ms). In combination with the PSS 10 HE and the software package HE hysteresis effects during measurements of high efficiency cells are eliminated. Options are available to further enhance functionality for production. A customized ”Plug&Play“ manual test station is also offered.
