DEVICE FOR TESTING A CONCENTRATED PHOTOVOLTAIC MODULE

摘要

The invention relates to a device for testing a concentrated photovoltaic module comprising at least one assembly of a photovoltaic cell and of a concentrator, the device being characterized in that it comprises: a light source; a parabolic mirror coupled to the source so as to reflect the light emitted by the source in an almost collimated light beam toward the module to be tested, in a direction perpendicular to the surface of the module; and an intensity filter interposed on the path of the almost collimated beam upstream of the module to be tested, the filter comprising at least partially absorbent regions that have a neutral spectral density with respect to the light beam, the at least partially absorbent regions being arranged facing higher intensity zones of the beam, so as to attenuate differences in the intensity of the beam.

1. A device for testing a concentration photovoltaic module comprising at least one assembly of a photovoltaic cell and a concentrator arranged relative to the cell to concentrate to the cell radiation arriving at normal incidence, the device comprising:
at least one light source, at least one parabolic mirror coupled to the light source so as to send back the light coming from the light source in an almost collimated light beam to the module to be tested, in a direction perpendicular to the surface of the module, and an intensity filter interposed on the trajectory of the almost collimated beam upstream of the module to be tested, the filter comprising at least partially absorbent regions with neutral spectral density relative to the light beam, the at least partially absorbent regions being arranged facing areas of greatest intensity of the beam so as to attenuate the differences in intensity of the beam.
