Schematic depicting layers of the microwire (MW) solar cells used in this work. MW inset shows that the solar cells are designed to extract carriers from the surface region of silicon: (1) surface recombination losses are reduced by depositing an AlOxpassivation layer; (2) bulk recombination losses are reduced by employing shallow radial p-n junctions through the MW architecture, as well as a microgrid array for the top aluminum electrode.
