Total Solution for Perovskite (Solar Simulator)

  After Perovskite solar cells exceed 10% power generation efficiency in 2012, as a result of R&D overlap, the cell efficiency exceed 25% in March 2020, and module (300mm x 300mm) efficiency exceed 16%. Furthermore, combining perovskite with a silicon cell (perovskite-silicon tandem solar cell), it has set a record of over 29%∗¹. Perovskite cells are extremely thin due to their structure and can be directly applied or printed on substrates, so they are drawing attention as next-generation solar cells.

  The perovskite solar cells that have made such rapid progress have been in the spotlight of the industry, and are steadily progressing toward further efficiency improvement and practical application (commercialization). However, due to the characteristics of the perovskite structure, the properties are more unstable than other solar cells (such as silicon), and the hysteresis and poor response also make accurate measurement difficult.

  SAN-EI has provided numerous solar simulators and measurement-related systems to domestic and overseas research institutes and companies for many years. This experience allowed us to accumulate a wealth of know-how and technology in solar cell research and development and manufacturing. While focusing on the future potential of this perovskite solar cells and the needs of our customers are increasing, we are paying attention to the features and characteristics of the perovskite solar cells, and proposes a total solution for measurement including high quality solar simulators.

For Cell

  Since the size of perovskite solar cell is mainly 20mmx20mm at the stage of research and development, we recommend the portable solar simulator XES-40S3 (beam size: 40mm X 40mm) or XES-50S2 (beam size: 50mm X 50mm).

  The lens head of our portable solar simulator can be changed in 4 directions, so it is convenient to use in combination with a glove box. In addition, as a default specifications the filter slot make it easy to add an optical filter (size: 50mm x 50mm).

Model : XES-40S3 / XES-50S2
Beam size: : 40mm X 40mm / 50mm X 50mm
Lamp : 150W Xenon lamp

For Module

  Due to recent technological advances, modularization of perovskite solar cells is progressing, and it is expected that modules of 300 mm x 300 mm size have reached the practical level for commercialization. Our high precision solar simulator XES-300S1 has cleared all AAA of JIS / IEC / ASTM standards, and the effective irradiation area completely covers 300mm x 300mm, which is ideal for perovskite module measurement. It has been well received and provided to many domestic and overseas customers.

* 350mmx350mm beam size is possible as a special order.    

Model : XES-300S1
Beam size: : 300mm X 300mm
Lamp : 3KW Xenon lamp

For tandem perovskite solar cell / module

   Since tandem perovskite solar cells differ in the spectral responses (quantum efficiency) of each element cell and the correction of spectral mismatch error is complicated, accurate measurement (photoelectric conversion characteristic evaluation) is technically more difficult than single-junction solar cells. Therefore, it is necessary to measure the characteristics under a solar simulator that has a spectral distribution that matches the reference spectrum as much as possible. Our 2 lamp type high-spectrum match solar simulators XHS series boasts the best performance in the industry and provides the most light near to real solar spectrum.

■Spectral mismatch error:
There are three patterns of spectral mismatch error.
1) Spectrum mismatch between solar simulator and reference spectrum (AM1.5G, AM0, etc.).
2) Mismatch in response between reference cell and unknown solar cell.
3) In the case of multi-junction solar cells, the spectral response of each element cell does not match.

These spectral mismatches lead to a kind of measurement error called spectral mismatch error that is quantified by the spectral mismatch factor.
