Basic Introduction
SS-X Solar simulator adopted a Xe short-arc lamp as the broadband light source.
Xe lamp has 6000K color temperature which is closest to nature sunlight (5500K).
All SS-X series solar simulators not only utilize optical simulation software to simulate the
optical and mechanical system design, but also adopt Fourier-optics technology to
generate the spatial uniform irradiance, which has been used in semiconductor mask
aligner with excellent prove.
The AM1.5G filter of SS-X solar light simulator, which is made with the advanced
Plasma Deposition technology, has the high spectral accuracy and the excellent
durability for the triples service lifetime. The better spectrum grade makes SS-X
suitable than any other simulators to characterize a wide variety of new solar cells such
as low-bandgap organic solar cells and perovskite / Si tandem solar cells. SS-X can
provide the stable and continuous irradiance to illuminate the solar cells under test, which
can avoid the characterization errors due to the slow responses time of these solar cells.

4. Compact but Flexible
The SS-X adopts the medical-
device-level power supply
system, which provides the
smaller electrical ripples. The
better electrical current output
allows the irradiance temporal
instability of SS-X solar light
simulator to achieve the better
A+ grade. This better
irradiance instability makes it
possible to discover the more
detail science of the new
generation solar cells such as
perovskite solar cells.
SS-IRIS: Exclusive
patent technology for
auto-light-intensity
manipulating
SS-IRIS is the exclusive
patent of Enlitech. It is the
sole technique in the world
that it can automatically
change the irradiance intensity
without changing the spectrum
of the irradiance, at the same
time. The irradiance range can
be tuned from 0.01sun to 1sun
(1mW/cm2~100mW/cm2) with
1% accuracy.

Output Beam Directions
SS-X series solar simulators support the function of setting the output beam direction.
The flexible output directions provide users with more application fields.
• Normal: the standard output beam direction is up-to-down direction.
• Bottom-up: upward output beam direction, which is suitable for integrating with
the glove box integration.
• Right & Left: sideways configurations which is generally used to illuminate the
water-splitting cells.

6. 6
Integrated Optical Shutter
In SS-X series solar simulators, beam size above 100mm x 100mm, are all integrated
with a single-blade mechanical shutter. It can be controlled by the Xe Power Supply
manually or automatically, and switch status from Open to Off within 199ms.
Xe Power Supply
The Power Supply of SS-X series solar simulators has the features below:
• 3.5” color-touch-panel.
• Digital timer, up to 9999 hours to monitor the lamp life.
• Digital lamp voltage and current display.
• Over voltage/ over current/ over temperature warning.
• Cooling Delay time control after lamp shutdown.
• Illuminator cover safety lock warning and light source auto shutdown.
• Built-in programmable shutter control module.
• Built-in programmable SS-IRIS aperture control module.
• RS232 port.

Reference Cells
Enlitech provides the world’s most types of reference cells which comply with the WPVS type
and IEC 60904 standards. The purpose of reference cells is helping accurately characterize the solar
cells to catch up the rapid development of the variety of new solar cells. The unique optical filter
embedded technology helps build different spectral wavelength range response of reference cell,
which can reduce the spectral mismatch between the solar simulators and new type solar cells.
The calibrated reference cell is an indispensable part of solar simulator calibrations and accurate solar
cell characterizations. Enlitech’s calibration laboratory accredited through the ISO / IEC 17025
standard. All of the SRC-2020 series reference cells are calibrated through tracing to NREL or ISE
Fraunhofer. Enlitech also provides the re-calibration service for reference cells.。
Enlitech provides several kinds of solar reference cells which are used to calibrate the illumination
intensity of sun light simulators or solar simulators. The Spectral response currves are shown below.
Each reference cell package will provide a WPVS packaged Si reference cell with the optical window,
two Lemo-connector cables, and one certified sun light intensity calibration report.

IVS-KA6000：The Most Powerful IV measuring software
All SS-X series solar simulators can be controlled by the IVS-KA6000 software which is the most
powerful IV measuring software for accurate PV characterizations. Not just the optical shutter, the
output light irradiance also can be manipulated by the IVS-KA6000 IV software, which can help users
easily finished the complex IV tests under different light intensities or Sun-Voc testing. All the IV data
from IVS-KA6000 can be read and analyzed by IVS-KA-Viewer, which is the other multi-functional
analyzing software.
In the past, to measure and fitting the ideality factor n of a solar cell is not easy and time-consuming.
For example, it generally costs one hour to get ten IV curves under 10 different light intensities. After
that, it also takes around one hour to sort out these data. However, with help of our testing solution,
SS-X solar simulator + IVS-KA6000 + IVS-KA-Viewer, the ideality factor N can be measured and fitted
within few minutes. If you are interested in it, please feel free to contact us.
※The latest version of IVS-KA6000 Perovskite Solar Cells IV Measuring and Analysis Software has
added current monitoring and measurement functions with shutter cycle control. It is currently open for
download and update. Free trial of IVS-KA6000 Software is also available for a limited time. Welcome
to download the software in “Resources and Download” section of the IVS-KA6000 page” and
experience!

Solar Cell Calibration and Testing Laboratory
Enlitech‘s Calibration Laboratory is the world’s first commercial company who pass
the ISO / IEC 17025 accreditation in the PV field in 2012. We provide solar cell
conversion efficiency certifications by advanced testing instruments, including SS-X solar
simulators and the QE-R quantum efficiency testing system. In 2020, we already finished
the accreditation transition from ISO / IEC 17025:2005 to ISO / IEC 17025:2017, which is
the latest calibration laboratory operation standard and provide the better quality of
certification services. We can provide solar cell quantum conversion efficiency and
quantum efficiency measurements according to IEC 60904-1 and IEC 60904-8,
respectively. All of the working standards and testing results are traceable to SI units
through the calibrations by NREL, Fraunhofer ISE, or NIM.

The Maintenance of SS-X
• SS-X series solar simulators can maintain A+ spectral performance during the
“Performance Lifetime” which is not equal to “Lamp lifetime.”
• Any simulator needs to be re-aligned and adjusted after changing the lamp in order to
achieve the required performance.
• Enlitech provides field measurement and adjustment services by professional and
qualified engineers.
• Enlitech provides maintenance service even expired the warranty period to help your
system keeping in conditions.

Q & A
Q: What is the Uncertainty value by using Enlitech’s solar simulator to perform PV IV testing?
The international standard ISO GUM (Guide to the Expression of Uncertainty in Measurement) stipulates
the evaluation and calculation of uncertainty, which is a globally consistent standard. All calibration and
testing laboratories accredited by ISO / IEC 17025 have the ability to analyze uncertainty in accordance
with ISO GUM and have been assessed and certified by accreditation organizations in various countries
to comply with international mutual recognition agreements.
Enlitech‘s photoelectric calibration laboratory has passed ISO / IEC 17025 third-party international
certification for 7 years. Therefore, Enlitech is very experienced in the analysis of quantum efficiency and
solar cell maximum power testing.
NREL and Enlitech’s total Uncertainty capability (k=2) for PV testing:
(will be slightly different according to actual conditions, such as sample stability, etc.)
* Enlitech uses standard solar reference cells calibrated by NREL to be traceable to SI units. Therefore,
the total uncertainty will be slightly higher than that of NREL.
