Scientists in China developed a method for preparing porous SiO2 materials by combining electron beam co-evaporation with selective chemical etching. Based on this method, all-silica ultraviolet laser ...

A European group of scientists has created a novel hydrophobic antireflective (AR) coating for the cover glass of PV modules. The double-layer coating uses a silica-titania (SiO2-TiO2) thin film as ...
