Problems solved by technology

[0005] Objects of the present invention: 1. When making photovoltaic vacuum ceramic panels with ceramic materials, the molded vacuum ceramic panels will be deformed during the drying or preliminary sintering of the mud body, and the temperature of the green body at 1100°C-1400°C During the firing process, due to the melting of the metal in the mud body to fill the gaps, the body has a strong shrinkage of up to 15%, so that the numerous pins in the pin array are not evenly connected to the corresponding surfaces, but also produce Larger gaps and even distortions; 2. To solve the existing photovoltaic vacuum glass, because the tempering performance of the glass will be seriously reduced during the production process, so the product is not safety glass and cannot be used in buildings, especially the supports cannot be completely connected to the two sides The vacuum wall is connected, resulting in uneven stress on the vacuum wall and the support, resulting in bursting, and the support between the two pieces of glass is prone to displacement or even slipping, etc., which seriously affects product application and industry development. The production process provided Manufacturing method of photovoltaic vacuum ceramic panel with low energy consumption and simple manufacturing method and photovoltaic vacuum ceramic panel

Abstract

The invention belongs to the technical field of photovoltaic power generation and energy-saving building material production, and particularly relates to a photovoltaic vacuum ceramic plate making method and a photovoltaic vacuum ceramic plate, so as to solve the stubborn problems that the tempering performance of the glass is seriously reduced during the making process of the existing photovoltaic vacuum glass, strong thermal expansion deformation stress which is difficult to release is generated at a support column portion of the inner layer glass, and bursting is likely to happen. The photovoltaic vacuum ceramic plate making method and the photovoltaic vacuum ceramic plate disclosed in the invention have the advantages that due to the flexible adhesive sealing material on the inner surface of the side wall of the protection shell and the outer surface of the side wall of the outer wall, the protection shell and the side wall of the photovoltaic shell vacuum ceramic substrate are bonded as a whole, the thermal expansion stress of the photovoltaic shell vacuum ceramic substrate is effectively released, and necessary preconditions are provided for placement and maintenance of solarcells; due to the side wall and shell structure, a three-dimensional force structure is formed by the photovoltaic shell vacuum ceramic substrate, the bending strength and the flexural strength are enhanced obviously, and the shear strength around the photovoltaic shell vacuum ceramic substrate is enhanced obviously; and due to the reflecting and cooling layer, the heat generated by the solar cell can be effectively reflected and attenuated. Integration of structures and functions of power generation and heat preservation can be realized.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation and energy-saving building material production, and in particular relates to a manufacturing method of a photovoltaic vacuum ceramic panel and a photovoltaic vacuum ceramic panel. Background technique [0002] There is only photovoltaic vacuum glass at present, and there is no report about photovoltaic vacuum ceramics. Difficulties in making photovoltaic vacuum ceramic panels with ceramic materials: 1. Due to the formed vacuum ceramic panels, deformation will occur during the drying or preliminary sintering of the mud, and the deformation effect is far greater than the unevenness of flat glass; 2. During the firing process of the vacuum ceramic plate at 1100°C-1400°C, the blank body will inevitably shrink strongly due to the melting of metal objects in the mud body to fill the gap, and this shrinkage can be as high as 15%. Therefore, it is the key to the production of vacuum...
