Cover plate and manufacturing method thereof, solar glass, photovoltaic device

Abstract

A cover plate and a method for manufacturing the same, a solar glass, and a photovoltaic device are provided. The cover plate (500) is adapted for covering a work device which, in operation, causes an electric field in the cover plate. The cover plate (500) comprises: a transparent substrate (530), having a first surface and a second surface opposite to the first surface, the first surface being adjacent to the work device; and a barrier structure, having at least one of a first barrier layer (510) on the first surface and a second barrier layer (520) on the second surface, configured to prevent performance degradation of the work device caused by leakage current and / or metal ions migration.

Description

technical field [0001] The invention relates to the field of optical materials, in particular to a cover plate and a manufacturing method thereof, solar glass, and a photovoltaic device. Background technique [0002] Glass is transparent, strong, airtight, chemically inert in everyday environments, and does not interact with living things, so it has a wide range of uses. Common glass includes automotive glass, flat glass, thermal insulation glass, etc. [0003] Glass is also used in photovoltaic devices as a cover for solar cells in photovoltaic devices. refer to figure 1 , shows a schematic diagram of an embodiment of a prior art photovoltaic device. The photovoltaic device includes: a substrate 11; an adhesive layer 12 on the substrate 11, and a plurality of solar cells 13 are also arranged in the adhesive layer 12, and the solar cells 13 in this embodiment are crystalline silicon cells; plate glass14. The substrate 11, the adhesive layer 12 and the cover glass 14 con...
