6 Frequently Asked Questions about “Calibration method for ground-based solar cells”
What types of solar cells can be calibrated?
Thus, calibration services are available for nearly all kinds of PV-devices; including wafer-based standard silicon solar cells in lab and industrial formats, as well as thin-film devices from various materials.
When was the first solar cell Calibration Workshop held?
The First International Workshop on Space Solar Cell Calibration and Measurement Techniques took place in Honolulu, Hawaii in December of 1994 and was attended by thirty-four participants from Japan, the United States and Europe representing not only the space agencies but industry as well (Brinker et al, 1995).
Does CalLab PV cell have a calibration program?
CalLab PV Cells continues to develop additional calibration experience, allowing for measurements which do not (yet) fall under the accreditation. These calibrations and measurements are performed with the same equipment and reference standards as accredited calibrations.
What topics are covered in a solar cell lab?
The topics covered include space environment and standard testing condition for solar cells, the measurements of key parameters for traditional solar cells, advancements in PSCs and organic solar cells for space applications, and a comprehensive review of diverse calibration methods.
How are space solar cells measured?
The measurements of space solar cells are typically performed in a lab environmentusing dedicated solar simulators.

How is irradiation intensity measured in a solar cell?
For solar cells with non-uniform/non-continuous busbars an adapted contact unit is used. The irradiation intensity is re-adjusted in order to have the shading-free short circuit current, as determined in Step 4, flowing through the cell. Then, the IV-curve is measured.
