Load and Measuring Device

PC controlled load simulation and IV curve measurement for solar cells including 1000 W/m², 500 W/m² and Dark Reverse test

The PSL SCD is optimized for fully automated production lines. It records three complete IV curves at 1000 W/m², 500 W/m² and Dark Reverse in one measurement cycle. Options are available to enhance functionality for production.
A customized ”Plug&Play“ manual test station is also offered.
