SS-PST100R AM1.5G Spectrum Adjustable Solar Simulator


With the rapid development of high-efficiency tandem solar cells, especially perovskite/crystalline silicon tandem solar cells, the need for accurate measurement of the conversion efficiency of tandem cells has attracted a lot of attention.


According to the latest IEC 60904-1-1 tandem cell test regulation, for the accurate test of tandem solar cells, the requirements for the simulator are as follows:

• Output spectral mismatch less than 6% (A++ grade)
• Output spectrum adjustable
• Output light intensity adjustable
• Using the latest single xenon light source spectrum control technology of Enlitech, the spectrum can achieve the spectral level of dual lamp system (xenon lamp plus halogen lamp).
• The output spectrum from 300-1700 nm can meet the requirements of AM1.5G spectrum, and its average spectral mismatch is less than 6% (IEC 60904-9: 2020).
• Only a single xenon lamp is used, so the system is free from two issues: (1) the lifespan of the two bulbs (xenon & halogen) of the dual lamp system does not match, and (2) the lifespan of halogen lamps is very short (only 50 hours).
• With A++ spectral grade. Moreover, its xenon lamp lifespan can exceed 1,000 hours, and it is much longer than the lifespan halogen lamp (1000 hours vs. 50 hours).
• Significantly reduces light source calibration time and increases reproducibility of the testing results.
• The design of single lamp source has better spectral coverage (SPC) and lower spectral deviation (SPD) than multi-lamp LED simulators. SS-PST can provide more accurate tandem solar cell testing results.
• SS-PST is especially suitable for precise testing of perovskite/crystalline silicon tandem solar cells due to its performance of spectrum adjustable.

   The comparison of SS-PST and other sun simulators.

According to IEC 60904-9:2020 standard, SS-PST not only has spectral grade of A++, 100% SPC, but also better SPD! A single lamp system has the performance of dual lamp system.
