Building material photovoltaic thin-film vacuum component

Abstract

The invention provides a building material photovoltaic thin-film vacuum component, which is characterized by comprising a vacuum thin-film cell and a translucent plate, wherein the vacuum thin-film cell is formed by directly coating the surface of a piece of vacuum glass, electrodes are led out from the edge part of the vacuum glass, and the translucent plate is glued with the vacuum thin-film cell through EVA (Ethylene Vinyl Acetate). In the invention, the vacuum glass serves as a substrate, the vacuum thin-film cell is manufactured by directly coating on the vacuum glass, and after the vacuum thin-film cell is in press fit with the translucent plate, sunlight penetrates the translucent plate and irradiates on the thin film, so that the component can generate power. As a vacuum layer is arranged in the middle of the vacuum glass, the component has excellent heat-insulating property.

Description

technical field [0001] The invention relates to a building material photovoltaic product for solar power generation, in particular to a building material photovoltaic film vacuum component. Background technique [0002] With the rapid growth of the BIPV application market, in order to directly apply crystalline silicon solar cells and thin-film solar cells to buildings as part of building materials, most photovoltaic module manufacturers use patchwork to make building material photovoltaic components. The main manifestations are as follows: i) use two pieces of glass to sandwich crystalline silicon solar cells in the middle, and use PVB / EVA to make laminated crystalline silicon photovoltaic modules; ii) use a piece of glass and thin film solar cells, use PVB / EVA made into laminated thin film photovoltaic modules; iii) using a piece of vacuum glass and thin film solar cells, using PVB / EVA to make laminated film or crystal silicon vacuum photovoltaic modules; Thin-film or cr...

Problems solved by technology

[0003] The above-mentioned packaging structure only improves the load-bearing capacity of crystalline silicon or thin-film photovoltaic components. Although the components have the function of generating electricity, they do not have the excellent heat insulation and energy-saving performance required by building materials.

This kind of encapsulation method using multi-layer glass composite, the photovoltaic components are too bulky, and the building load increases, resulting in an increase in construction costs

On the other hand, the above-mentioned photovoltaic component packaging structure has many production processes, the quality is difficult to control, and the quality consistency is poor.

The product cannot really replace traditional building materials, and its higher price is not accepted by most people
