Unisim Close-Match Solar Simulators

TS-Space Systems is the first and only 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 PV research tool designed for the accurate measurement of multiple junction devices, including the new generation of four junction devices.

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.

Our IV measurement software is included for free with any Unisim or Class AAA solar simulator.

Temporal Stability

Our method of defining temporal stability is to take a number of IV readings in quick succession, and to look at the reproducibility of the various parameters. Below is shown the typical IV curve achieved with these simulators. Below that are the results of ten successive readings and their analysis.

UV Extended Solar Simulators

19/10/2011: TS-Space Systems apologises for the delay in the announcement of our UV Extended Solar simulators. Following from the large demand we have had for our Unisim close-match solar simulators, we have decided to combine our UV Extended simulator technology into the next generation of 'Ultra Close Match' TS Space Systems Solar Simulators, which will build off of our award winning Unisim Solar Simulator series.

Class A/B

For customers who do not require the high spectral match or spectral zone control available from our Unisim solar simulators TS-Space Systems also produces class A/A/A and class B/A/A solar simulators based on metal halide sources which:

• provide high output
• are relatively cheap
• require only air cooling
• allow rapid lamp changes
• (most importantly) provide high stability

Our IV measurement software is included for free with any Unisim or Class AAA solar simulator.

High Flux Beam Concentrator Simulators

TS-Space Systems is now proud to announce its world leading solar simulator technology is now available for concentrator high flux beam simulator applications.

Class A Concentrator Solar Simulators

Our 'Class A' high flux beam systems are available with the following specifications:

- 600 suns @ 10mmx10mm area
- 1200 suns @ 10mmx10mm area

Close Match Concentrator Solar Simulators

Modifications can be made to our close match 'Unisim' solar simulators to provide a concentrator solar simulator.

This provides the world leading AM1.5 spectral close-match of TS-Space systems in a high flux beam concentrator solar simulator of 40-50 suns.

Uniformity Mapper

The measurement of beam uniformity is critical when setting up or maintaining a solar simulator. In order to reduce the time and effort required to manually position and record a single sensor reading across multiple target positions, TS-Space Systems can provide the TS Uniformity Mapping unit.

The unit consists of a wired 10x10 array of calibrated, 1cm^2 Hamamatsu Si diodes which are interrogated by two high speed USB DAQ units. The included Labview based software provides a display of the beam uniformity in a variety of graphical formats (eg. as a 3D surface, 2D projection, wireframe etc.) so that the effect of optical adjustments can be observed in real-time allowing you to quickly and easily set up your simulator's beam uniformity. 'Snapshots' of the acquired data and plot can be exported to Microsoft Excel 2007 (not included) for further analysis or archiving.

A 'swap-in' unit is also available for use with our 4-zone Unisim solar simulators which uses Ge based diodes in order to measure the fourth zone (1200-2500nm).
