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.
We are proud to house and manage one of the few commercial photovoltaic and calibration test laboratories in the world.
