Method for determining temporal and spatial changes of volume- and/or packing concentration of substance in samples during production of solar cells, involves calculating material parameter using software

摘要

The method involves collimating polyenergetic primary radiation (2) that is generated by an X-ray source (1). The radiation is monochromotized by a monochromator (4), and is directed using an X-ray capillary lens (3). A sample (6) is irradiated in a selective geometric direction using the monochromotized beams. Concentration courses over entire sample height are calculated under utilization of particle size-independent attenuation coefficients of continuous and dispersive phases. A material parameter is calculated using a software under consideration of forces causing concentration change. An independent claim is also included for a device for determining temporal and local changes of volume- and/or packing concentration of a substance in samples.
