Spectral Quantum Efficiency
The Oriel QE/ICPE Kit is a turn key system from Newport for spectral quantum efficiency measurements of solar cells. It includes a 150W xenon arc lamp, Cornerstone 260 1/4m monochromator complete with chopper and filter wheel attached, current preamplifier, Merlin digital lock-in amplifier, calibrated silicon detector head and TracQ Basic software interface for automated spectral QE measurements.
In addition, two 300W xenon arc lamps supplied by Newport provide additional light…
Temperature Dependent I-V and QE
The CTI-Cryogenics Cryocooler is a closed–cycle liquid helium cooled cryostat. The cold head is mounted on a slide rail for convenient positioning in front of the spectral QE measurement kit for low temperature QE or white light I-V measurements down to 5K. The cold finger accepts 24-pin DIP ceramic packages and other custom mounted samples. A custom Labview interface operates with a Lakeshore 331/332 temperature controller and Keithley 2400/2420 source meter for automated I-V vs…
Solar Cell Probe Station
The solar cell probe station is equipped with an Oriel Class A Solar Simulator. Solar cell I-V measurements can be performed on a temperature controlled chuck with Keithley 2420 source meter and a CCD microscope for alignment.
