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

ECN has developed a new cell- and module design for crystalline siliconsolar cells called PUM (Pin Up Module) based on old patents. In this design, a limited number of holes (typically 9 or 16) serve as vias for interconnection of the front side metallisation to a foil at the rear side by using pins. In this way busbars at the front side are eliminated, thus reducing shadow losses leading to an efficiency increase of 0.4% absolute. The presented interconnection concept will facilitate easier module manufacturing. In this paper, we present results of two methods to produce Pin Up Modules. In principle it is possible to interconnect cells in a module without loss in fill factor. First steps towards a fully automated module production are being made. 9 refs.
