Due to an increase in quote requests for our test services we have a new form for requesting quotes for vacuum testing which can be found here. Although we specialise in custom testing requirements, collating common test requirements using this initial form will help us get your quote out much faster.

We are also in the process of updating our standard outgassing test information to cover regular questions and problems we are asked regarding sample preparation. For our existing customers please note our outgassing charges will remain the same for 2017, so if you used us for your outgassing test work in 2016 and are looking to use us again in 2017, the prices are the same.

We'd like to wish all of our customers and clients a very Merry Christmas and a Happy New Year!

2016 has seen a particular increase in demand for our in-house test and consultancy services and we are grateful for all of the interest, feedback and references you've given us. We will be working on further expanding our test services in 2017.

We are also always working on our Unisim range of solar simulators which continue to lead the world in solar simulation and 2017 will be no different. We are working on new products, designs and also an expansion of our in-house solar simulator service for next year.

Please note that we will be closing for the Christmas period from the 22/12/16 to 02/01/17 so please contact us with your requirement before then, otherwise we will see you all in 2017!

The full download for our latest IV measurement software v4.1 is available via the download link below.

For more information on our IV measurement software see our product page.

The full IV measurement system source code is included with any of our Unisim solar simulators including our new Unisim Compact solar simulator.

We are very proud of our extensive customer list which includes some of the most prestigious research and commercial groups working in photovoltaics today and we are very happy to be able to add SJ Solar and Tulane University department of Physics and Engineering Physics to that list.

If you would like more information on our 4-zone Unisim close match solar simulators with LED boost zone options, please have a look at our brochure or contact us to discuss your requirements.

If you are interested in our close match Unisim Compact solar simulator designed for smaller research applications, please see our new informational video or download the brochure for a full overview of what is possible with our Unisim range of solar simulators.

We have started an IV software support page for our free IV measurement software.

All full version installers and sub version patches will be available here. If you have any problems installing or running the software then please post a description of your problem on this support page.

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.

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.
