Characterization of MAE-textured nanoporous silicon for solar cells application: Optics and surface passivation

Chong, Teck; Weber, Klaus; Booker, Katherine; Blakers, Andrew


We present a three-step metal-assisted chemical etching (MAE) texturing technique to fabricate nanoporous Si (MAE nSi). The relationship between the resulting surface morphology, optical properties, and surface recombination of the MAE nSi are presented and analyzed. We also show that the solar weighted reflectance Rw of unencapsulated MAE nSi is less than 12% for all MAE nSi samples investigated in this paper. We show that the texture morphology has a near-isotropic surface reflectance for...[Show more]
