A method of making a photovoltaic device including an antireflective coating, including: forming a coating solution by mixing a mono-metal oxide, a bi-metal oxide, a silane, or a siloxane with a solvent, such that the coating solution may be used as a barrier between the antireflective coating and a glass substrate that inhibits sodium ion migration in the glass substrate after exposure to environmental factors including humidity and temperature. A photovoltaic device including a photovoltaic film, a glass substrate, and a barrier layer provided on the glass substrate; an anti-reflection coating provided on the glass substrate and on the barrier layer; wherein the barrier layer comprises one or more of the following: a mono-metal oxide, a bi-metal oxide, a silane, or a siloxane. |
