Abstract: A solar cell module and a method for operating a solar cell module. The solar cell module includes a plurality of strings which are each formed from a plurality of solar cells connected to one another in a series circuit, wherein each string is connected to a bypass circuit assigned thereto. The solar cell module is also characterized in that the bypass circuit has a switching element and is configured to reduce an electrical current inside the string by switching the switching element when a return current occurs within the associated string.

Abstract: A kit comprising a solar module having a positive-pole cable comprising a positive pole plug, and a negative pole cable comprising a negative-pole plug, a spacer. The spacer comprises a first flat part spanning a first flat part plane together with first flat part outer edges, and a further flat part spanning a further flat part plane together with further flat part outer edges. The first flat part has fixing means and/or the further flat part has further fixing means. The first flat part and the further flat part configured to be mounted on one another such that the first flat part plane is arranged at a fixing angle to the further flat part plane and forms, between the first flat part plane and the further flat part plane, a plug recess located a distance from the first flat part outer edges and the further flat part outer edges.

Abstract: The present disclosure relates to a device for preparing, in an automated manner, at least one sample for analysis by means of matrix-assisted laser desorption ionization in combination with a mass spectrometric analysis, and to a corresponding method. The device comprises a sample-receiving area which is surrounded by a housing and forms an internal volume which is closed off from the surroundings, a loading/unloading device for introducing the sample into the sample-receiving area and for removing the sample from the sample-receiving area, a heating unit configured to heat at least the sample-receiving area, and a vacuum device configured to generate a vacuum in the sample-receiving area.

Abstract: A solar cell module (100) comprises a first terminal (101) and a second terminal (102), a plurality of solar cells (110) and a switch (120). The solar cells (110) can be electrically connected to one another between the first terminal (101) and the second terminal (102) in order to generate a voltage between the first terminal (101) and the second terminal (102) in normal operation. The switch (120) electrically connects the first terminal (101) and the second terminal (102) to one another in a default setting or isolates the plurality of solar cells (110) from the first or from the second terminal (101, 102) and can be controlled in such a way that, when a valid control signal is present, the first terminal (101) is electrically isolated from the second terminal (102) or the plurality of solar cells (110) are connected to the first and the second terminal (101, 102).
