LIVS(LINE I-V Scanner) ＰＶＣ－３３００T

OVER VIEW
This system, PVC-3300T, adopts a new measuring method which is different from many existing
testers using solar simulator.
PVC-3300T is that,
1) a light-source head (linearly aligned LED’s) moves from end to end over the entire
light-receiving surface,2) and the optical I/V characteristics of each linear division are measured sequentially at everystep,3) then using the information of the inner-surface distribution, that is of parameters obtained byscanning, PVC-3300T diagnoses and evaluates performance uniformity and detects defective
points of the tested panel.
It is speedy; scanning time of entire surface of a 300mm x 300mm sized panel is about 10
seconds (*1) (*2).
(*1)

When measuring I/V under the following conditions:

5mm-scanning width x

60 lines and 200 steps per line.
(*2)

Display speed is not considered. Scanning time may change depending on
response speed of the tested panel.

FEATURE
1. PVC-3300T can diagnose modules of up to the maximum testing size.
2. The light-source head scans the surface of a module. Then I/V characteristics of each line of
the whole area will be measured and defective points are detected.
3.The light-source head is a combination of white and infrared LED’s. This two-color
combination enables to obtain the characteristics information in the depth direction of a thinfilm. (Different output power for each white and infrared LED’s can be assigned.)
4.The irradiance of the light source is 80mW/cm2, that is 80% of a solar simulator(100mW/cm2).
5. It takes only about 10 seconds for scanning the entire 300mm x 300mm area.
6. Isc (short-circuit current), Voc (release voltage), Pmax (maximum output power), and FF (fillfactor) are calculated in real time, so these characteristic values can be applied to Quality
judgment at a production line.
