Presented at: 16th European Photovoltaic Solar Energy Conference and Exhibition, Glasgow, Scotland, 1-5 mei 2000.

This paper summarizes recent testing with single and double layer stencilprinting in comparison with screen-printing. The comparative electrical test results for cells produced by screen and stencil printing during experiments utilizing various numbers of cells are reported. Pastes are evaluated for their printing definition. With stencil printing a more consistent cell output and a higher output over a full production run of several thousand wafers are obtained. Further it is demonstrated that, when selected pastes are used stencils allow for printing high aspect ratio fingers. 6 refs.
