Abstract. In this study, we fabricated n-type bifacial solar cells by liquid phase deposited (LPD) SiO 2 films as surface passivation layers. We have found that the growth conditions of LPD SiO 2 films have great influence on the deposition rate of the LPD SiO 2 films. Besides, the surface passivation effects of LPD SiO 2 films on both p-type and n-type silicon wafers are enormously improved after annealing at a temperature higher than 700 °C. Finally, the optimized LPD SiO 2 films have been successfully applied to the n-type bifacial silicon solar cells as the surface passivation layers, achieving a conversion efficiency of 19.06% on a large size (156 mm×156 mm) solar cell.

Surface coating is considered to be an efficient method to control the corrosion of carbon steel. Sol-gel silica coatings and hydrophobic silane-silica coatings were prepared on the substrates of polished and phosphated carbon steel and were characterized with scanning electron microscopy, energy-dispersive spectrometry, X-ray photoelectron spectroscopy and contact angle analyzer. Corrosion behaviors of these coated samples were investigated by potentiodynamic polarization tests in 3.5 wt% sodium chloride solution at 25°C. Uniform, flat and dense silica coatings were formed on the phosphated carbon steel. The contact angle of water increased from about 70°on silica coating to 127°on hydrophobic silane-silica coating, while there was no significant change on contact angle by phosphating pretreatment. Both of the corrosion potential and polarization resistance of the coatings increased and the corrosion rate decreased with phosphating pretreatment. However, the addition of silane could reduce the corrosion resistance of the coatings to a certain degree, and most coatings had defects such as cracks, which were adverse to corrosion prevention.

SiO2 film coatings were used to modify the surface of metal mesh for corrosion protection using liquid phase deposition and sol‐gel methods at low temperature. Different techniques were applied to characterized the as‐prepared samples. The results show an enhanced corrosion protection of the SiO2 deposited samples in comparison to the unmodified samples, as well as the SiO2 deposited sample prepared with sol gel method provides the better corrosion protection when compared with the liquid phased deposited sample, which mainly contributes to its compact morphology. The hydrophobic SiO2 coatings also exhibit excellent corrosion resistance since hydrophobic modification can hinder the contact with environment.
