Microchannel contacted solar cell concept. (a) Basic fabrication procedure for microchannel contacted solar cells, (b) Comparison of aspect-ratio for conventional and microchannel based solar cell contacts, the individual figures approximately reflect their size relative to each other. Cross sectional SEM images of (c) high aspect-ratio microchannel (90° cross section); (d) triangular microchannel (90° cross section); (e) textured surface bonding (45° cross section); and (f) magnified bonding to textured surface (45° cross section).
