The SS-X Solar simulator uses a Xe short-arc lamp as the broadband light source. The Xe lamp has a 6000K color temperature, which is closest to natural sunlight (5500K). All SS-X series solar simulators not only utilize optical simulation software for the optical and mechanical system design, but also adopt Fourier-optics technology to generate spatially uniform irradiance. This technology has been used in semiconductor mask aligners with excellent results.

The AM1.5G filter of the SS-X solar light simulator, made with advanced Plasma Deposition technology, has high spectral accuracy and excellent durability, tripling the service lifetime. The superior spectrum grade makes the SS-X more suitable than other simulators for characterizing a wide variety of new solar cells, such as low-bandgap organic solar cells and perovskite/Si tandem solar cells. The SS-X can provide stable and continuous irradiance to illuminate the solar cells under test, which helps avoid characterization errors due to the slow response times of these solar cells.

A+ Spectrum: the closest to AM1.5G standard spectrum

The AM1.5G filter of the SS-X solar light simulator, which is made with advanced Plasma Deposition technology, has high spectral accuracy and excellent durability, tripling the service lifetime. The superior spectrum grade makes the SS-X more suitable than other simulators for characterizing a wide variety of new solar cells, such as low-bandgap organic solar cells and perovskite/Si tandem solar cells.

Compact but Flexible

 

 

The SS-X adopts a medical-device-level power supply system, which provides smaller electrical ripples. The improved electrical current output allows the irradiance temporal instability of the SS-X solar light simulator to achieve a superior A+ grade. This enhanced irradiance instability makes it possible to uncover more detailed science of 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 only technique in the world that can automatically change the irradiance intensity without altering the spectrum of the irradiance simultaneously. The irradiance range can be adjusted from 0.01sun to 1sun (1mW/cm2~100mW/cm2) with 1% accuracy.

Output Beam Directions

　　The SS-X series solar simulators support the function of setting the output beam direction. These flexible output directions provide users with more application fields.

1.Normal: The standard output beam direction is downward.

2.Special: There are two types as below (please contact our sales for options)

2.1 Bottom-up: Upward output beam direction, which is suitable for integration with the glove box.

2.2 Right & Left: Sideways configurations which are generally used to illuminate water-splitting cells.

Integrated Optical Shutter

　　In SS-X series sun simulators 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 diverse types of reference cells, which comply with WPVS type and IEC 60904 standards. The purpose of reference cells is to help accurately characterize solar cells to keep pace with the rapid development of various new solar cells. The unique optical filter embedded technology helps build different spectral wavelength range responses of the reference cell, which can reduce the spectral mismatch between the sun simulators and new types of solar cells.

　　The calibrated reference cell is an indispensable part of sun simulator calibrations and accurate solar cell characterizations. Enlitech’s calibration laboratory is 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 a re-calibration service for reference cells.

　　Enlitech provides several kinds of solar reference cells, which are used to calibrate the illumination intensity of sunlight simulators or solar simulators. The spectral response curves 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 sunlight 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 can also be manipulated by the IVS-KA6000 IV software. This can help users easily finish 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 another multi-functional analyzing software.

　　In the past, measuring and fitting the ideality factor n of a solar cell was not easy and time-consuming. For example, it generally took one hour to get ten IV curves under 10 different light intensities. After that, it also took around one hour to sort out these data. However, with the help of our testing solution, SS-X solar simulator + IVS-KA6000 + IVS-KA-Viewer, the ideality factor N can be measured and fitted within a few minutes. If you are interested in it, please feel free to contact us.

 

Solar Cell Calibration and Testing Laboratory

　　Enlitech‘s Calibration Laboratory became the world’s first commercial company to pass the ISO / IEC 17025 accreditation in the PV field in 2012. We provide solar cell conversion efficiency certifications using advanced testing instruments, including SS-X solar simulators and the QE-R quantum efficiency testing system. In 2020, we completed the accreditation transition from ISO / IEC 17025:2005 to ISO / IEC 17025:2017. This is the latest calibration laboratory operation standard and it provides better quality 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 our working standards and testing results are traceable to SI units through calibrations by NREL, Fraunhofer ISE, or NIM.

The Maintenance of SS-X

• SS-X series sun simulators can maintain A+ spectral performance during the “Performance Lifetime,” which is not equal to “Lamp Lifetime.”
• Any simulator needs to be realigned and adjusted after changing the lamp to achieve the required performance.
• Enlitech  provides field measurement and adjustment services by professional and qualified engineers.
• Enlitech provides maintenance service even after the warranty period has expired to help keep your system in good condition.
