Abstract

A solar battery pack with a double-layer toughened glass structure comprises a surface layer, an upper ethylene-vinyl acetate copolymer layer, a solar battery layer, a lower ethylene-vinyl acetate copolymer layer, and a back plate layer, which are sequentially laminated from top to bottom and are packaged together, wherein both the surface layer and the back plate layer are high-strength low-iron toughened glass. The solar battery pack has the advantages of good light effect, high wind resistance and hail resistance, and good appearance, and can be used for glass curtain wall of large buildings.

Description

1. Technical field [0001] The invention belongs to the field of new energy photovoltaic power generation, and in particular relates to a solar battery module with a double-layer tempered glass structure and a preparation method thereof. 2. Background technology [0002] Existing technology: Due to the increasingly severe global energy crisis and environmental problems, people's demand for new energy and non-polluting renewable energy is becoming more and more urgent. Solar photovoltaic power generation is a promising technology in new energy and renewable energy. field. [0003] The most basic components of solar photovoltaic power generation are solar cells, including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. A solar panel composed of one or more solar cells is called a photovoltaic module, or a solar cell module. A solar cell module is a device that converts solar energy into electrical energy. It has various installation...
