Stencil master for solar cell and method for printing electrode of solar cell

FIELD: printing.

SUBSTANCE: invention relates to stencil master for use in printing conductive paste for simultaneous generation of bus electrode and a plurality of finger electrodes on solar element. Said stencil master includes an opening for bus electrode and multiple openings for finger electrodes, and the hole widths for finger electrodes is less than 80 mcm, and the stencil master has multiple blocked zones in the hole for bus electrode, formed only in positions aligned with holes for finger electrodes.

EFFECT: use of this stencil master for stencil screen printing method allows to cut the cost of solar cells, to protect connection between the bus electrode and a finger electrode against damage causing no increase of loss because of solar cells shadowing or loss of its aesthetic quality, and to make high-reliable solar cells of high capacity.

FIELD: technological processes.

SUBSTANCE: invention is related to galvanoplastics. Matrix for galvanoplastics of printing screens includes matrix plate, on which metal is deposited for moulding of printing screen. Matrix plate includes the main surface of deposition, on which metal deposited to create the main body of printing screen, at least one pair of edge segments at the opposite borders of the main deposition surface, which include edge segments of deposition, which come out from plane produced by the main deposition surface, on which metal is deposited to create fastening elements of printing screen, and angular sections in appropriate angles of deposition surface. Matrix also includes non-conducting elements in the form of edge elements, which are located at edge sections so that they create length of these edge sections, and non-conducting elements in the form of angular elements, which are located near angle sections so that they protect them and create length of the main deposition surface near these angular sections.

EFFECT: expansion of assortment of produced items.

FIELD: technology for producing thermo-sensitive material for stencil printing forms, engineering of device for producing said material, engineering of stencil printing machines.

SUBSTANCE: material for printing forms is made only from film of thermo-plastic resin by usage of polyether film in such a way, that aperture, through which paint may permeate, can be thermally perforated without increasing power of thermo-printing head. Film is a thermo-sensitive material for stencil printing forms 12, having given thickness, and consists of stretched mylar film or stretched film with low melting point, produced by copolymerization of polyethylene therephthalate and polybutylene therephthalate. A set of smallest raster cells 14 is formed on one side of film by transfer of template. Transfer of template may be performed under working pressure 104·102(m-t)/(m-g) Pascals or higher, when working temperature is t°C, melting point temperature of film is m(°C), and temperature of film vitrifying is g(°C).

EFFECT: decreased power of thermo-printing head, facilitated operations with film.
