Stencil printing is introduced as a technique to improve the quality ofthe front grid metallisation of crystalline silicon solar cells. An evaluation of the most suited production method learned that electroformed nickel stencils are best suited for solar cell application. An electroformed nickel double-layer stencil was developed and the rheology of the silver paste was adapted for stencil printing. Printing results using a single-layer stencil showed that using a high-viscosity paste high and fine metal lines, 54 m width and 22 m height, can be made. 10 figs., 2 tabs., 11 refs.
