Efficiency as a function of the cell length for various specific contact resistances (see legend, Rscr, in Ω cm2), and TCO (without contact resistance) for cells with finger grid width of 20 µm (a,c,e) and 60 µm (b,d,f) and a height of 2 µm (a,b), 5 µm (c,d) and 50 µm (e,f). Calculations were based on a 19% small cell.
