PV Cell Tester 200L

EETS PV Cell Tester 200-L is a steady state system.

Designed to achieve a high accuracy measurement and archived record of output.

Utilising a group of LED light sources to meet IEC 904-9 class A(AM1.5) spectral distribution.

The cooling system comprises a recirculating chiller that controls the temperature of the plate to within 0.2ºC. By circulating through a heat exchanger unit underneath of the cell-mounting block.

A computer based DAQ system acquires the cell performance data and controls the electronic load, which varies the resistance across the cell. The computer plots the I-V curve and displays a variety of cell characteristics. Curves and data can be printed and/or stored on disk for later processing.

The EETS PV Cell Tester200-L measures the current-voltage (I-V) characteristics of PV cells up to 157mm x 157mm. The steady-state light is adjusted to the required intensity and is measured by a calibrated reference cell.

A data acquisition system acquires the cell performance data and controls the electronic load which varies the resistance across the cell output terminals. The computer plots the I-V curve and displays a variety of module characteristics. Curves and data can be printed and archived.

The system is desk mounted. The system contains the light source, integrated test jigs and a laptop PC.

The light source constitutes a purpose-built lamp housing with the LED boards and drivers. The other components of the light source are the power supply, and variable intensity controller.

Measures and displays the following:

  • Complete I-V curve.
  • Open Circuit Voltage Voc.
  • Short Circuit Current Isc.
  • Maximum Power Point Pmp.
  • Module Efficiency.
  • Fill Factor.
  • Module Temperature.
