摘要： In a method and devices for forming a temporary electrical contact to a solar cell for testing purposes, probes form a contact to the electrode terminals of a solar cell held by a sample holder. The probes are held by a probe holder and exhibit an elastic, electrically conductive contact element and at least one reference sensor. In order to form a contact, the solar cell and the probes are positioned in relation to each other, and then a probe is placed on an electrode terminal of the solar cell. To this end, a feed motion of the probe is carried out until a reference sensor of the probe generates a reference signal upon reaching a predefined distance. Then the feed motion is continued by a predefined path that goes beyond the contact element making contact with the electrode terminal, in order to carry out an overtravel.

摘要： A probe for temporarily electrically contacting a solar cell for testing purposes, has at least one elastic, electrically conductive contact element for producing the electrical contact, at least one reference sensor for indicating a distance of the contact element to an external reference surface using an electrical signal of the reference sensor, and a mounting plane to which the tip of the contact element is oriented. The probe ensures a secure electrical contact of the solar cell in a testing station with minimal mechanical stress, and is also suitable for use in an industrial continuous production method.

摘要： A chuck with triaxial construction comprises a receiving surface for a test substrate and arranged below the receiving surface: an electrically conductive first surface element, an electrically conductive second surface element electrically insulated therefrom, and an electrically conductive third surface element electrically insulated therefrom, and, between the first and the second surface element, a first insulation element and, between the second and the third surface element, a second insulation element. A chuck for very low current measurements which can be used to prevent the occurrence of leakage currents and a triboelectric charge and which is configured favourably in terms of production, is achieved because at least one of the electrically conductive surface elements is mechanically connected to at least one insulation element and has an elasticity that compensates for an expansion difference resulting from differences in different coefficients of expansion between a respective surface element and an adjoining insulation element.

摘要： An arrangement is provided for testing DUTs with a chuck that has a support surface for supporting of a DUT as well as for supplying the support surface with a defined potential, or for connecting the DUT. The arrangement further includes a positioning device for positioning the chuck as well as an electromagnetic shielding housing enclosing at least the chuck. Inside the housing and adjacent to the chuck, a signal preamplifier is arranged whose signal port facing the chuck is electrically connected with the support surface, wherein the signal preamplifier is moveable together with the chuck by the positioning device in a way that it holds its position constant relative to the chuck during positioning. The signal preamplifier is connected to a measurement unit outside of the housing via a measurement cable.
