FCT-450: Light I-V Testing for Solar Cells

Advanced analysis of solar cells including light I-V and Suns-Voc data. Capability to accurately measure high-efficiency conventional or backside-contact solar cells.

The removable chuck plate allows for multiple backside contact chucks to be rapidly interchanged with the front contact chuck.

Product Overview

The FCT-450 has been designed to have the highest possible accuracy for measuring high-efficiency solar cells. This is done using patented Voltage Modulation to neutralize the capacitive effects in I-V measurements.

The Sinton analysis package includes standard cell test outputs. It is supplemented with the Suns-Voc analysis that precisely indicates the source of power loss with accurate shunt and series resistance measurements.

System Capabilities

Primary Application:

  • One-sun cell flash testing
Analysis Techniques:

  • Suns-Voc curve
  • 5-point testing utilizing Suns-Voc, Jsc, Vmp
  • I-V curves at multiple intensities (MultiSuns Analysis)
  • Efficiency versus intensity characteristic
