Spectral Response SystemsQuantum Efficiency SystemsIPCE Measurement Systems
QE system provides electronics and software designed for fully automated measurement of external quantum efficiency of solar cells. All systems include probes and a fixed plate sample stage for samples up to 150 mm x 150 mm. The main system components include: custom designed software, measurement electronics, and computer system (Windows 8 operating system). The measurement involves focusing monochromatic light to a spot on the device under test, then accurately measuring the photon flux and current from the test cell. The system utilizes a dual beam configuration with lock-in detection, providing an absolute accuracy of ±3%. The QE system uses a grating monochrometer with silicon/InGaAs/Ge detectors. The system includes automatic order sorting filters and two light sources for monochromatic illumination (a Xenon- arc lamp and a halogen lamp). A single lock-in amplifier is used to measure both the reference detector and test device. The main system comes with all the hardware needed to measure quantum efficiency, a fixed plate sample stage and probes.

Solar Simulator
Unisim
TS-Space Systems is the first company to pioneer the use of metal halide sources in solar simulators for photovoltaic testing. The high temporal stability and close spectral match combined with the ability to control the output spectrum via multiple separate wavebands means the Unisim solar simulator is the only solar research tool designed for the accurate measurement of multiple junction devices, including the new generation of four junction devices. As with all our Unisim solar simulators, they exceed the ASTM, IEC and JIS international standards for spectral match and temporal instability. Using the latest HMI and halogen luminaire technology, the Unisim solar simulator provides a highly stable area of illumination. The simulators also use cutting edge filter technology in order to provide the best spectral match available for AM0 and AM1.5. Further to this, the spectrum can be achieved via two, three or four separate spectral wavebands which allows a high degree of spectral control for research and development. Product support is very important to us. Training is provided at our premises where customers can take advantage of one-on-one tuition with the instrument designers and learn how to operate and maintain their tools. Extensive support via phone and email for the full lifetime of the instrument is included with every TS-Space Systems product.
