Abstract
A solar cell testing apparatus may include an illuminator for directing light energy on a solar cell under test. The solar cell testing apparatus may also include a device for selectively positioning different filters of a multiplicity of filters in an optical path between the illuminator and the solar cell under test to at least one of measure performance and detect any defects in the solar cell. The multiplicity of filters may include a first set of filters and a second set of filters. Each filter of the first set of filters is adapted for passing a predetermined percentage of intensity of the light energy from the illuminator onto the solar cell under test. The second set of filters being adapted for testing the solar cell under different spectrums of light.
