Problems solved by technology
Due to the various characteristics of graphene itself, it can not only improve the effect of the suede surface of the silicon wafer and increase the output; but also can well avoid the deposition of silver on the surface of the roller, which solves the problem of the distribution of silver in the later stage of the chain black silicon liquid. Improve the service life of the chemical solution, improve the efficiency of black silicon cells and reduce the proportion of low-failure cells

Abstract
The invention relates to a novel roller processing method in solar cell texturing equipment. The method includes the following steps: 1) preparing graphene; 2) transfer of graphene; the scheme improves the texturing output of silicon wafers and the uniformity of the textured surface To solve the problem that the adsorption of silver on the rollers in chain-type black silicon texturing equipment affects the life of the liquid medicine and the efficiency of cells, and provides a new type of roller used in solar cell texturing equipment.
Description
technical field [0001] The invention relates to a processing method, in particular to a novel roller processing method in solar cell texturing equipment, and belongs to the technical field of crystalline silicon solar cell processing. Background technique [0002] The chemical properties of graphene are similar to graphite, and graphene can adsorb and desorb various atoms and molecules. When these atoms or molecules are used as donors or acceptors, the concentration of graphene carriers can be changed, while graphene itself can maintain good conductivity. But when adsorbing other substances, such as H + and OH - When , some derivatives will be produced, which will make the conductivity of graphene worse, but no new compounds will be produced. The structure of graphene is very stable, and the carbon-carbon bond is only 1.42. The connection between carbon atoms inside graphene is very flexible. When an external force is applied to graphene, the surface of the carbon atoms ...
