Device for electrically contacting a solar cell during the measurement of electrical characteristics of the solar cell, and method for measuring electrical characteristics of a solar cell

A device for electrically contacting a solar cell during the measurement of electrical characteristics of the solar cell, wherein the solar cell is embodied with a multiplicity of finger electrodes on a solar cell surface, the device comprising:

• at least one measuring strip extending between two measuring strip end sections in a measuring strip extension direction, wherein the at least one measuring strip has at least one contact terminal for electrical contacting with a solar cell test device;
• a plurality of contact spring sections arranged on the at least one measuring strip along the measuring strip extension direction, wherein each contact spring section is configured to electrically contact at least one finger electrode of the multiplicity of finger electrodes by spring-elastic mechanical contact when the at least one measuring strip is placed onto the solar cell surface, with the measuring strip extension direction oriented transversely with respect to the multiplicity of finger electrodes;
• and
• a measuring frame having frame edge struts situated opposite one another, which, with the frame edge struts, engages around an area that is greater than or equal to a solar cell to be measured, wherein the at least one measuring strip and the contact spring sections are formed from a same material and integrally, wherein each contact spring section is embodied in a looped or hooked fashion as viewed transversely with respect to the at least one measuring strip extension direction, and the measuring frame has a mechanical tension device, in which the at least one measuring strip is clamped under tensile stress between the frame edge struts situated opposite one another, the tensile stress being applied in the measuring strip extension direction, such that the measuring strip is fixed between the frame edge struts.
