Nondestructive and Fast Spectral Response Measurements for PV Modules

This LED-based pulse quantum efficiency (QE) system enables NREL to measure the spectral response of PV modules quickly and reliably, without the need to individually tab cells. And it offers a custom map of spectral response at different locations.

A solar module sits underneath a square shade that covers several cells around the measured cell. A bundle of black fibers runs from LEDs to the center of this shade to measure the desired cell.
