Aligned Single-Crystalline Si Nanowire Arrays for Photovoltaic Applications

Silicon nanowires (SiNWs) with desirable axial crystallographic orientations can be readily prepared by a novel chemical‐etching technique (see SEM image). The as‐synthesized SiNW arrays significantly suppress reflection over the visible‐light spectral range and are therefore promising candidates fo...

Description
Summary:Silicon nanowires (SiNWs) with desirable axial crystallographic orientations can be readily prepared by a novel chemical‐etching technique (see SEM image). The as‐synthesized SiNW arrays significantly suppress reflection over the visible‐light spectral range and are therefore promising candidates for antireflection coatings of photovoltaic cells despite exhibiting a lower efficiency than non‐nanowire‐based devices at this stage of development.
