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.7 cl, 13 dwg, 1 tbl |
