Fireproof crystalline silicon photovoltaic module

Abstract

The invention discloses a fireproof crystalline silicon photovoltaic module. The module is characterized by comprising fireproof glass sheets (1) of the bottom layer and the top layer, wherein a middle layer is two layers of sealant films (2); and a crystalline silicon cell sheet (3) is arranged between the two layers of sealant films (2). Damage of fire disasters to buildings can be prevented through the fireproof crystalline silicon photovoltaic module, and the crystalline silicon photovoltaic module which is used for the photovoltaic buildings and keeps the integrity of self performance can be applied to fields, such as fire prevention of the buildings, and the like.

Description

technical field

[0001] The invention relates to a fireproof crystalline silicon photovoltaic module, which belongs to the field of solar photovoltaic technology. Background technique

[0002] Among many energy sources, solar photovoltaic power generation is the most technological and promising way of new energy and renewable energy. The solar photovoltaic cell module is a device that converts light energy into electrical energy under sunlight irradiation, which is composed of glass, crystalline silicon cells, wires, wiring devices, and bonding materials. Recently, building-integrated photovoltaic technology, which organically integrates photovoltaic power generation systems and buildings, is being widely used. Compared with the traditional use of solar cells, integrated photovoltaics and buildings have many advantages: for example, integrated photovoltaics and buildings A part of the cost of building materials becomes an integral part of photovoltaic cells, which saves the ...

Examples

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0013] Example. A fireproof crystalline silicon photovoltaic module, such as figure 1 As shown, the fire-resistant glass sheet 1 includes the bottom layer and the top layer, and the middle layer is two layers of sealant film 2, and a crystalline silicon battery sheet 3 is sandwiched between the two layers of sealant film 2. The fireproof glass sheet 1 is Li 2 O-Al 2 o 3 -SiO 2 It is transparent fireproof glass-ceramic, monolithic fireproof borosilicate glass, aluminosilicate fireproof glass or high strength monolithic cesium potassium fireproof glass. The sealant film 2 is one of high temperature resistant polyvinyl butyral resin or ethylene-vinyl acetate copolymer. The thickness of the fireproof glass sheet 1 is 2-4 mm. The thickness of each layer of the sealant film 2 is 0.1-1 mm.
