We discuss the calibration chain of PV cells and modules, with particular emphasis on primary reference cell calibrations. We present the direct sunlight method our group has developed for these calibrations and discuss critical improvements and upgrades that lead to calibration uncertainty as low as 0.45%.
Three main measuring systems are required for the calibration of solar cells: one to determine the active area, another to determine the spectral responsivity, and a third one to measure the I–V characteristics.
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.
Therefore, this work can serve as a useful guide for implementing primary PV reference cell calibrations using the outdoor method, as well as outlining the critical elements required to make these calibrations highly accurate. This article is protected by copyright. All rights reserved.
The adoption of photovoltaic (PV) modules for clean electricity relies on accurate measurements of their performance, which are essential for estimating their energy production potential. We discuss the calibration chain of PV cells and modules, with particular emphasis on primary reference cell calibrations.
The measured values for voltage, current and temperature are recorded by separate and externally triggered calibrated multimeters. Both n- and p-type solar cells with edge lengths between 20 and 175mm and short-circuit currents of up to 15A are measured. Figure 2. CalTeC’s I–V curve measurement facility.
Precise and accurate solar cell measurements at ISFH CalTeC
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, …
