At Fraunhofer ISE, characterization and simulation of materials and cells play a major role in our cell development research. For the tandem technology, we carry out material analyses (silicon, III-V, perovskite crystals and layers) and cell characterization using many different approaches. Also our accredited calibration laboratory CalLab PV Cells is a valuable resource, providing quality assurance, traceable measurements and allowing for the comparison of devices with different materials, sizes and cell technologies. We work closely with industry to optimize the performance of conventional and novel solar cell technologies.
