  • Patent number: 12015379
    Abstract: A device for electrically contacting a solar cell during the measurement of electrical characteristics of the solar cell, which has a plurality of finger electrodes on its surface, has at least one measuring strip that has at least one contact terminal for electrically contacting a solar cell test device and that extends between two measuring-strip end portions in a measuring-strip extension direction. The measuring strip has a plurality of loop-like or hook-like contact spring portions formed integrally with the measuring strip, which are positioned on the measuring strip along the measuring-strip extension direction. The contact has at least one finger electrode by spring-elastic mechanical contact, when the measuring strip is placed on the surface of the solar cell. A measuring frame includes opposing frame-edge struts, which engages, using the frame-edge struts, around an area that is greater than or equal to a solar cell to be measured, and in which the measuring strip is braced.
