Ecosun Cell


LEDs with different wavelengths are used to cover the complete spectrum from 400 nm to 1100 nm. This allows a nearly perfect match with AM 1,5 which permits to obtain highly accurate efficiency measurements.
The cell tester is loaded manually and the cells are contacted by a dedicate probe mask to obtain the IV measurement during the light pulse.
The unit is designed to test 156 x 156 mm solar cells with 3 bus bar but it is possible to measure smaller cells or cells with different number of bus bars with minor modifications (kit available as option).
All the measurements and testing parameters are stored in a SQL database for an easy sharing and access from other PC or software.

  • Obtain the best from your cells
  • No more capacitive effects

  • Trace your measurement
  • Reduce the maintenance labour
