Abstract
A low-index silica coating may be made by forming a silica precursor having a radiation curable composition including a radiation curable monomer and/or a photoinitiator, and also including a silica sol comprising a silane and/or a colloidal silica. The silica precursor may be deposited on a substrate (e.g., glass substrate or silicon wafer) to form a coating layer. The coating layer may then be cured via exposure to electromagnetic radiation, such as UV radiation. Then, the cured coating layer may be fired using temperature(s) of from about 550 to 700° C., in forming the low-index silica based coating. The low-index silica based coating may be used as an antireflective (AR) film on a front glass substrate of a photovoltaic device (e.g., solar cell) in certain example instances.
