Device for electrical contacting of a solar cell in the measurement of electrical characteristics of the solar cell and method for measuring electrical characteristics of a solar cell

摘要

The invention relates to a device for electrically contacting a solar cell in the measurement of electrical characteristics of the solar cell, wherein the solar cell is formed with a plurality of finger electrodes on a solar cell surface, the device comprising at least one measuring strip (1) extending between two Meßleisten-end sections in a measuring strip extension direction (E), wherein the measuring strip (1) has at least one contact terminal for electrical contacting with a solar cell test device, and a plurality of contact spring sections (2) along the measuring strip extension direction (E) on the measuring strip ( 1) are arranged, wherein each contact spring portion (2) is formed when placing the measuring strip (1) on the solar cell surface, with the measuring strip extending direction (E) transverse to the finger electrodes at least one finger electrode electrically by a resilient mechanical contact to contact. According to the invention, the measuring strip (1) and the contact spring sections (2) are formed from the same material and in one piece, each contact spring section (2) being formed in a loop shape or hook shape, viewed transversely to the measuring strip extension direction (E). Furthermore, the invention relates to a method for measuring electrical characteristics of a solar cell by means of such a device.
