Large-area reference cell for sun simulators
Calibrate your sun simulators with utmost precision thanks to IMT Technology’s large-scale BigRef reference cell.
With its extremely precise calibration, BigRef allows users to determine the irradiance intensity of sun simulators precisely. BigRef is also suitable for determining local non-uniformities in sun simulators for PV modules.
The size of the solar cell as a sensor element brings considerable advantages compared to more compact WPVS reference cells since the size of the cell surface compensates for the non-uniformities in irradiation intensity to a certain extent.
Big Ref was developed and designed in cooperation with the solar cell calibration laboratory at the ISFH CalTeC in the German town of Hamelin.
