Latest Precise Measurement Solutions for Perovskite/Silicon Tandem Solar Cells

With the rapid advancement of solar cell technology, perovskite/silicon tandem solar cells have become a focal point of research due to their outstanding photoelectric conversion efficiency and broad application prospects. However, precisely measuring the performance of these advanced solar cells has remained a challenge. To address this issue, we present a comprehensive innovative solution to ensure accurate evaluation and optimization of your solar cells.

SS-PST Spectrally Adjustable/Super Class-A Spectral Solar Simulator SS-PST100R

Understanding the critical importance of accurate IV measurements and conversion efficiency testing for tandem solar cells, we developed the SS-PST100R solar simulator. This system not only provides super Class-A spectral accuracy but also features spectral adjustability, fully complying with the stringent requirements of the IEC 60904-1-1 standard. Its output spectrum achieves an A++ classification, maintaining spectral deviation within 6% of AM1.5G across all wavelength bands, providing optimal testing conditions for perovskite/silicon tandem solar cells.

IVS-KA7000 Spectral Control and IV Scanning Measurement Software

The implementation of spectrally adjustable solar simulators has significantly enhanced the precision of IV measurements for perovskite/silicon tandem solar cells. Our IVS-KA7000 software greatly simplifies the testing process through automated control and adjustment of the SS-PST simulator’s output spectrum and illumination intensity. When used in conjunction with the SRC-2020 multi-spectral reference cell, it achieves high spectral consistency with the AM1.5G standard, ensuring measurement accuracy and reliability.

WPVS Reference Solar Cell Set

To further enhance measurement accuracy, we provide high-precision WPVS Reference Solar Cells. These reference cells integrate seamlessly with the IVS-KA7000 software, automatically monitoring output spectral deviations from AM1.5G to ensure testing light source quality and result reliability.

Our SRC-2020-KG3 reference cell and top perovskite subcell demonstrate spectral mismatch factors (MMTOP) of less than 1%. The SRC-2020-BL7 reference cell, used for bottom cell light intensity calibration, also shows an MMbot of less than 1%. After adjusting the SS-PST solar simulator using SRC-2020-KG3 and SRC-2020-BL7 (both NREL-traceable calibrated, with spectral errors less than 0.5% for both top and bottom cells), we verified using an ISE-calibrated quartz window reference cell to measure light intensity deviation across 300nm-1200nm. The results (ISE QTZ) showed SS-PST light intensity output at 1.0052 Sun, merely 0.52% deviation from AM1.5G 1000 W/m², demonstrating the SS-PST solar simulator’s accuracy in simulating the AM1.5G standard spectrum.
