“…[228][229][230][231][232][233] In CVE a solution similarly to stain etching is made up from concentrated HF plus concentrated HNO 3 . However, instead of dipping the Si substrate in the solution, the substrate is held above the solution.…”

“…Infrared spectroscopy reveals a combination of hydrogen termination and oxidation of the surface. 228,230,231 Similarly to stain etching VE has incubation period. Saadoun et al 232 observed that for p-type Si the formation of the PSi layer begins at least 2 or 3 min after exposing the substrate to HNO 3 /HF vapors.…”

“…Research carried out by Ben Rabha et al 228 has shown that VE technique for Si porosification can be very attractive for fabrication antireflective coatings in solar cells. The use of conventional PSi formation techniques, like anodisation or "stain etching" for this purpose presents some difficulties compared to the CVE method.…”

“…1b). The average crystallite size D of the annealed TiO 2 nanoparticles (NPs) was estimated from XRD patterns using the Debye-Scherrer formulae [12]. The crystallite size was found to increase from 31 to 44 nm as the film thickness increases from 5 to 160 nm.…”

This work reports on passivation effect of solar-grade multicrystalline Si (mc-Si) using a TiO 2 /porous silicon double coating. For this purpose, TiO 2 nanoparticles were deposited onto porous silicon (PS)/mc-Si using pulsed laser ablation of titanium target. The structural and optoelectronic properties of the TiO 2 /PS treated mc-Si substrates were investigated by X-ray diffraction, Raman spectroscopy, optical spectrometry, photo-conductance and photoluminescence (PL). It was found that the minority carrier lifetime (s eff ) of the mc-Si wafer could enhance at a nominal thickness of the TiO 2 film (nanoparticle sizes). This was attributed to a surface passivation of the mc-Si wafer via TiO 2 -passivation of the PS film, whose PL intensity improves consequently. An optimal TiO 2 thickness of 80 nm was found to give the highest PL intensity and an enhancement of the minority carrier lifetime from 5 ls for untreated mc-Si wafer to about 391 ls for a TiO 2 / PS treated wafers.
