Measurement of Spectral Response

Measurement of spectral response on cell level

SR in the range of 300 nm to 1200 nm is measured using 42 monochromator filters for reference module. The spectral response data are used for the correction of the module measurement, thus it is necessary that the reference module is built up identically and with the same materials like the modules to be measured. For each type of module we need one additional module for spectral response measurements. We have to open the backside of that module in order to contact one single cell within the module. Please note that the module will be destroyed, since this is a destructive test.

 

Measurement of spectral response on module level

SR is measured in the range of 350 nm to 1100 nm using 29 bandpass filters in class A+A+A+ sun simulator. Wavelength interval is maximum 50 nm. The spectral response data are used for the correction of the module measurement, thus it is necessary that the reference module is built up identically and with the same materials as the modules to be measured. This spectral response measurement is a non-destructive test.
