The KOPEL KSJ-026 cell setter employs a self-alignment mechanism that enables high accuracy of ±0.05 mm to ensure stable probing of PV cells to be measured, thus achieving high repeatability of the measured data.

It is mounted with two dial gauges to precisely set and control the contact pressure of probe pins. In addition, the KSJ-026 cell setter is provided with a cell vacuum contact function and cell temperature control function to easily reproduce measurement conditions and stabilize the FF values.

A High-precision IV Test System that allows accurate measurement of IV of high-efficiency PV modules including HIT® with a 50-ms pulse light.
It is generally believed that a stationary light or a very long pulse (several hundreds of ms or longer) is needed to measure HIT® or similar high-efficiency PV modules. Kyoshin, however, has jointly developed an innovative test method, called the “KOPEL Method,” with Japan’s National Institute of Advanced Industrial Science and Technology (AIST).

By incorporating this KOPEL Method, the KSX-2012HM System is able to accurately measure IV of high-efficiency PV modules such as HIT® using both dark and illuminated IV data. Our IV data using a 50-ms pulse show very good agreement with the IV data measured for a long sweep time of 1000 ms under a stationary light source: the deviation is just 0.2-0.3%. Moreover, the KSX-2012HM System achieves extremely high throughput with the shortest emission interval of approx. 15 seconds.
