We have a new video featuring our Unisim Compact solar simulator which gives a guided tour of the system as well as some of the optional extras that can be fitted during manufacture.
The video also covers the concept of using the Unisim Compact solar simulator as a simplified 4-zone solar simulator. For more information on this, or how the LED boost zones work, see our technical note here.

With the advent of cells with more than four junctions, the basic design of the TS-Space Systems Unisim range reached its sensible limit. To provide for five and more junctions, the N-zone solar simulator was introduced. This is very sophisticated, and can be used to analyse cells with up to twelve junctions with-out the adjustment of any one junction affecting the other.
A simplified version of this simulator is now offered. This is based on our standard, spectrally close-matched simulators, but uses LED boost zones in place of the traditional arc and tungsten lamps, up to 1100nm. These are much more compact than our simulator zones, are extremely stable and perform well within the international standards for spatial uniformity of +/-2%.
The LED banks can be retrospectively installed in existing Unisim solar simulators or included at the point of manufacture. They are computer controlled using dedicated rack-mount power supply units which control the current limit and temperature of the individual LED's to automatically prevent any drift in wavelength. Custom software allows for computer
control of an individual LED as well as groups of LED's with the same wavelength. LED output configurations of the simulator can be saved and recalled.
The software automatically detects the LED units installed at start-up which allows the user to replace individual LED's or even install an alternative wavelength LED with minimal disruption to the control system. Thus any later changes to simulator wavelength requirements can be accommodated with minimal cost and downtime.
