Abstract: The invention relates to a method for improving the ohmic-contact behaviour between a contact grid and an emitter layer of a silicon solar cell, in which, in a treatment step, a treatment current flow having a current density of 200 A/cm2 to 20,000 A/cm2 in relation to the treatment section is induced while biasing and illuminating the silicon solar cell. The object of the invention is to improve the method for improving the ohmic-contact behaviour between a contact grid and an emitter layer of a silicon solar cell. In particular, it should be possible to quantify the improvement achieved by the method while implementing the method. Furthermore, any damage resulting from the application of unfavourable process parameters should be detected while the method is being implemented.

Abstract: A method for displaying stored, high-resolution, diagnostic 3D image data and 2D real time image data simultaneously, continuously and in parallel during a medical intervention of a patient utilizes an apparatus including a first unit for storing recorded diagnostic 3D image data sets and for performing dynamic coregistration thereof with a non-diagnostic 3D image data set and of the non-diagnostic 3D image data set with at least one 2D sectional data image set recorded in real time, a second unit for recording the diagnostic 3D image sets, a third unit for substantially instantaneously recording recording the real time 2D sectional image data sets, a fourth unit for displaying the diagnostic 3D image data sets processed by the coregistration, a fifth unit for displaying the real time 2D sectional image data sets, and data transfer connections.
