LED-BASED SOLAR CELL TESTER
LEDs with different wavelengths are used to cover the complete spectrum from 300 nm to 1200 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 156,75 x 156,75 mm solar cells with 4-5-6 bus bar but it is possible to measure smaller cells or cells with a different number of bus bars with minor modifications (kit available as an optional).
All the measurements and testing parameters are stored in a SQL database for easy sharing and access from other PC or software.
