We developed highly efficient (12.8%) nanowire solar cells by employing a self-aligned selective emitter structure without costly optical patterning. Using facile one-step etching, we obtained direct contacts between top-metal electrodes and degenerately-doped planar silicon, while concomitantly utilizing low-doped silicon nanowires as optical absorbers.
This resulted in improvement of all photovoltaic parameters (Voc, Jsc, and FF) in addition to a remarkable improvement (7.0 to 60.8% at 450 nm) in the blue response in the IQE.
