Solar energy is becoming more and more important all around the globe. Not only is it available in unlimited supply, it also offers key advantages for protecting the climate and the environment. Every year, many thousands of solar cells are produced worldwide for new photovoltaic plants. An important criterion for quality control is 3D characterization of the light-absorbing surface. In the past, this required time-consuming SEM
analysis. A Dual-Core 3D Measuring Microscope that combines confocal and interferometry technology offers non-contact, high-precision analysis of the surface texture of solar cells in a matter of seconds.
