Method and use of a cutting apparatus for manufacturing a CdS/CdTe thin film solar module

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, so that the point of the cutting tool slides over the surface of the contact layer during the relative movement of the cutting tool and the substrate. An Independent claim for a separation device for manufacture of a solar module is also included.
