Abstract

The invention discloses a lossless sample clamp of a solar battery current-voltage testing system and belongs to the technical field of solar battery current-voltage testing systems. A sample support (1) of the clamp is an iron plate comprising a center gold plating area (3) and is supported by four supporting feet (2). The screw-in depths of single-end studs and adjusting nuts with different numbers can be selected as required by the supporting feet (2) so as to adjust the distance between the sample support and a light source. A wire is in contact with a spring telescopic probe (5) by penetrating through a bolt bar (7). A fixing device provided with a positioning magnet is matched with the spring telescopic probe so as to position a battery or an assembly. A spring is arranged in the spring telescopic probe (5), the tip of the probe is a round head, and therefore the battery or the assembly can be clamped in a lossless mode. The lossless sample clamp can conveniently and flexibly install and detach samples which are small in area and not prone to being clamped and clamp samples which are expensive in a lossless mode so as to protect the samples. The contact resistance of an electrode is reduced, measuring is more accurate, manufacturing and operation are simple, and cost is low.
