We present the integrated development of back-contacted solar cells and an adequate module interconnection for a high-efficiency photovoltaic module. The impact of the busbars of our back-junction back-contact cells on the cell performance is analyzed, and we report on optimization of the cell/module interface. As a first step towards modules with busbar-free cells, we fabricated cells with only one busbar and interconnect them in series.
