The results presented show improved agreement for the calibration of PV modules with respect to previous international exercises. For thin-film PV modules, the preconditioning of the devices prior to calibration measurements is the most critical factor for obtaining consistent results, while the measurement processes seem consistent and

The performance of a photovoltaic module is mainly defined by the maximum power P max, which is measured under standard conditions (1000 W/m 2, AM 1.5, 25 °C) using a sunlight (natural or simulated) and a calibrated reference device. This reference photovoltaic device, placed in the same lighting conditions than the module under test, allows the

A main disadvantage of solar simulators is its price, which can easily exceed €150,000 for an AAA type. This cost is large enough to dissuade many possible PV practitioners (universities, engineers, etc.) from trying to measure PV modules accurately, as required under due diligence for controlling the delivered power of PV modules supplies or for PV reference

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.
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.
For the calibration of a solar cell, the cell area, the spectral responsivity (SR) and the current–voltage (I–V) curve have to be determined. The I–V curve then yields the characteristic parameters, including the power conversion efficiency, fill factor, short-circuit current and open-circuit voltage.
WPVS reference solar cells calibrated at the PTB are used for calibrating the DSR facility. I–V measurements are carried out using the light from a class AAA solar simulator (WACOM WXS-156 S-L2), shown in Fig. 2.
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).
The combined expanded uncertainty of the measurement of the maximum power of PV modules, among the most expertise laboratories, is between 1.6% and 3% . The electrical related uncertainty contributions are negligible, while major contribution in uncertainty is related to the irradiance measurement.
