Method of manufacturing a tin film solar module and an apparatus for cutting

摘要

The solar module manufacturing method uses a number of coating stages and layer separation stages for formation of a number of adjacent thin-film solar cells on the surface of a common substrate (12), with a cutting tool used for mechanical separation of a pn double layer (16) applied over an initial contact layer (14), for defining the cell structure. The contact layer has a higher hardness than the pn double layer, with the point of the cutting tool sliding over the surface of the contact layer during relative movement of the cutting tool and the substrate, for defining the separate solar cells without rotation or lifting of the cutting tool. An Independent claim for a separation device for manufacture of a solar module is also included.
