Cover plate, manufacturing method of cover plate, solar glass and photovoltaic device

Abstract

The invention discloses a cover plate, a manufacturing method of the cover plate, solar glass and a photovoltaic device. The cover plate is suitable for covering a work device, and the work device forms an electric field on the cover plate. The cover plate comprises a light-transmitting matrix, a barrier layer and an anti-reflex layer, wherein the light-transmitting matrix is provided with a first surface and a second surface which are opposite to each other, and the first surface is adjacent to and connected with the work device; the barrier layer is positioned on the first surface of the light-transmitting matrix and is used for preventing substances in the light-transmitting matrix from escaping under the action of the electric field so as to inhibit the performance degradation of the work device; and the anti-reflex layer is positioned on the second surface of the light-transmitting substrate and is used for reducing the reflection of incident light on the second surface of the light-transmitting substrate. The barrier layer is positioned on the first surface adjacent to the work device and can be used for preventing the substances in the light-transmitting substrate from escaping from the first surface under the action the electric field, thereby preventing the substances in the light-transmitting matrix from entering into the work device, and inhibiting the performance degradation, caused by the substances in the light-transmitting matrix, of the work device.

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.
