FCT-750 – In-Line Light I-V Testing for Solar Cells

In-line, light I-V and Suns-Voc measurements in a single flash at 3600 units per hour. Capability to accurately measure high-efficiency conventional or backside-contact solar cells.

Product Overview

The FCT-750 has been designed to have the highest possible accuracy for measuring solar cells, namely high-efficiency cells. This is done using a patented voltage modulation to neutralize capacitive effects in the I-V measurement.

The FCT-750 provides standard cell outputs which are supplemented with a Suns-Voc analysis and a substrate doping determination. All of these parameters are available in a single flash pulse.

System Capabilities

Single flash measurement to obtain:

  • Standard cell results: Isc, Voc, Power, Vmp, Imp, FF, Efficiency, Rs, Rsh
  • Advanced results: Suns-Voc, Bulk Lifetime, Jo, Doping, Pseudo I-V parameters
