A nanoporous silicon (Si) surface was formed on monocrystalline silicon solar cells by electrochemical etching. The galvanostatic mode was applied to conventional n–p–p + solar cells, which were fabricated by pyramidal texturing, phosphorous diffusion, screen‐printing, rapid thermal firing, and laser isolation (effective area of 144.7 cm 2 ). Without an additional antireflection layer such as SiN x , the anodic reaction of the Si wafer could provide uniform porous layers on a pyramidal surface (111) with relatively low reflectance, and it would improve the photovoltaic performance.
