A novel low‐aspect‐ratio Si nano‐ hemisphere array surface texturing is introduced to enhance the performance of Si thin‐film solar cells, which show ahigher short‐circuit current density thannanopillars. Simulation shows thatphotogenerated carriers are mainlyconcentrated within a thin layer on thenano‐hemisphere array surface (the insetscheme is scaled to the size of a hemisphere) due to a strong light‐absorbing effect. The demonstrated nano‐hemispheres are highly compatible with and promising for Si thin‐film‐based solar cells.
