Solar cell graphite boat electrode holder and solar cell graphite boat

Abstract

The invention discloses a solar cell graphite boat electrode holder and a solar cell graphite boat. Steel sheets are respectively arranged on the outer sides of clamping pieces of the electrode holder and the two steel sheets are connected through a welding block to limit the loosening position of the clamping pieces, and due to the fact that the steel sheets are good in elasticity and shape recovering capacity, the steel sheets play a certain role in calibrating the clamping pieces, deformation of the electrode holder is prevented, generation of chromatic aberration pieces caused by the deformation of the electrode holder is avoided, the service life of the electrode holder can be greatly prolonged, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a solar battery graphite boat electrode clip and a solar battery graphite boat. Background technique [0002] Graphite boat for solar cells, referred to as graphite boat, is a boat-shaped carrier made of graphite for silicon wafers. It consists of two electrode clips connected to electrodes and several graphite blades. Two adjacent graphite blades are connected to different electrodes. . The existing electrode clip is mainly composed of two clips. During the research and practice of the prior art, the inventor of the present invention found that the electrode clip is generally made of copper with good conductivity, and the elasticity and shape of copper The memory is not very good, so the electrode clip is easy to deform after a period of use, for example, the gap between the two clips will gradually become loose, or it will deviate from the middle position and bend to one s...

Problems solved by technology

The existing electrode clip is mainly composed of two clips. During the research and practice of the prior art, the inventor of the present invention found that the electrode clip is generally made of copper with good conductivity, and the elasticity and shape of copper The memory is not very good, so the electrode clip is easy to deform after a period of use, for example, the gap between the two clips will gradually become loose, or it will deviate from the middle position and bend to one side, etc. The poor contact of the graphite boat will eventually lead to the generation of aberration film. In order to avoid this situation, the electrode clip has to be replaced regularly, and the service life of the electrode clip is short
