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.

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).

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.

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.
