Preparation of SiO_2 antireflective film on large area ultrawhite glass by roll coating method

摘要

SiO_2 antireflective film was successfully coated on the large area ultrawhite glass (300 mm×300 mm) by roll coating method. The effect of the concentration of the SiO_2 and the annealing temperature on the photovoltaic transmittance of the film was studied and the hardness and the adhesion of the film were tested. The transparent antireflective film with the highest photovoltaic transmission of 95.7% was obtained.
