| SOLAR
CELL TESTER |
| The
tester is assigned for terrestrial solar cell incoming/outcoming
inspection with the purpose of optimizing parameters and
preventing manufacture defects of solar modules.
|
 |
|
|
|
| Due
to use of xenon pulse lump installed in the tester solar cells are
not heated in process of inspection.The tester is IBM PC
controlled with the possibility of selecting inspection duty: from
simple check in a particular I-V curve point up to full I-V curve
recording and statistical processing of measurement results. |
