“…From the values of it is concluded that an increase in the porosity of the nanoPS layers leads to an increase in the value of the optical . This behavior is attributed to the change in the composition from bulk Si to a matrix of air (pores), amorphous silicon and Si nanocrystals [10,15,23]. Accordingly, the optical properties of nanostructured porous silicon can be adjusted depending on the intended application by the change in the morphology and porosity of the bulk material.…”

“…The pore surfaces are covered by silicon hydrides (Si-H) and silicon oxides (Si-O). Existence of pores, especially the canal-form pores, which determine large ion (proton) conductivity along the pores opens new perspectives for using porous silicon-based structures as hydrogen fuel cells [2].…”

“…Polymer Electrolyte Membrane (PEM) cells, known as proton exchange membrane cells, are now considered the leading for automotive applications. PEM fuel cell is a thin, flat, multilayered "sandwich" and is made up of two electrodes (anode and cathode) surrounding by polymer electrolyte [1]. The porous silicon wafer filled with acid or Nafion ® was developed as a proton conducting membrane [2].…”
