TSIV Software Update v4.1

28/7/2016

 
A new update for our TSIV IV measurement software is available to download via the link below. The full installer version will be updated soon and available on the main IV measurement software page.

Updates:

- Isc and Voc are now estimated at beginning of automatic sweep to define sweep parameters.

- Isc and Voc are now interpolated from the main IV sweep and not separate single point measurements.

- VFwd and IL are now interpolated from the main IV sweep and not separate single point measurements.

- Fixed a bug when sweeping amps that would hang if OVP was triggered before retrieving data from SMU.

What's a solar simulator "zone"?

11/6/2015

 
solar simulator spectrum
Spectral irradiance comparison between AM0 standard (ASTM E-490) and TS-Space Unisim: (a) irradiance from each of four lamps indicated by “zone” numbers and vertical blue markers indicate band gaps of typical IMM four junction solar cell; (b) percent of total irradiance for each of six wavelength regions as specified by IEC 60904-9.[1]
At TS-Space Systems, when we made the worlds first multi-source close match solar simulator back in 1997 [2], we also made the world's first multi zone solar simulator by definition. What is a "zone" when it comes to solar simulators? It's a good question and one we get asked quite a lot of the time.

Modern multi-source solar simulators follow a general pattern of combining an arc lamp (traditionally Xenon) with one or more  incandescent lamps. At TS-Space Systems we've lead the way by adopting Metal Halide arc lamps for our latest range of solar simulators which are cheaper and much more stable than Xenon sources without using feedback controllers.

But where our solar simulators really excel is their division of the spectrum into independently controllable wavebands. We call these spectral "zones". As an example, the measured spectrum of a TS-Space Systems Unisim, quad-source (four zone) solar simulator is shown to the left.

The intensity of each "zone" can be adjusted independently in a TS-Space Systems Unisim solar simulator. Being able to adjust discrete portions of the spectrum while a device is under test allows for specific sub-cells to be limited or saturated with their appropriate wavelength of light. Thus the behaviour and characteristcs of the device can be fully investigated.

A further distincition can therefore be drawn between advanced solar simulators which provide a close-match and those which not only provide a close-match, but divide the spectrum into controllable "zones" which are suited to the spectral response of each band gap within the solar cell. 

What happens when you need more than four "zones"? That's where our Unisim N-Zone comes in.
