Fraunhofer Institute for Solar Energy Systems ISE
We measure your solar cells and PV modules with high precision, speed, and reliability.
In photovoltaics, the precise measurement of solar cells and modules is of critical importance. The Fraunhofer ISE CalLab photovoltaic calibration laboratory is one of the world’s leading laboratories offering measurement services.
We measure all types of solar cells and PV modules precisely and reliably in accordance with international standards. We have state-of-the-art equipment at our disposal for this purpose. We also develop our own specialized precision measuring instruments.
To ensure we consistently meet the highest quality standards, we regularly participate in international interlaboratory comparisons with other calibration laboratories.
If you want to know the efficiency of a solar cell exactly, it is likely that you will land in Freiburg, Germany sooner or later. For 30 years high-precision reference solar cells – and for almost 25 years reference modules – have been measured at the CalLab PV Cells of Fraunhofer ISE. Researchers, producers and plant operators order calibrated cells to have their own benchmarks. It is comparable to the “model meter“ in Paris: If you have one copy of that standard, you can always check your in-house measurement equipment against it. Since CalLab PV Cells is internationally renowned and certified, any research value published with the certificate of Fraunhofer ISE will automatically be more credible. CalLab PV Cells was founded in 1986 with three co-workers. Today 30 employees calibrate about 2,500 solar cells and 5,000 solar modules each year.
