Embodiment Construction

[0020] A flexible crystalline silicon solar cell module, such as figure 1 As shown, it consists of a transparent film layer 1, a hot-melt adhesive film layer 2, a crystalline silicon battery layer 3, a hot-melt adhesive film layer 2 and a back film layer 4 from top to bottom; The vinyl fluoride copolymer layer, the hot melt adhesive film layer 2 is an ethylene-vinyl acetate copolymer layer, and the back film layer 4 is a polyvinylidene fluoride layer. The above five layers are packaged by heat lamination. The crystalline silicon battery is made of 156*40 flexible battery slices welded in series by tinned copper strips, and the battery slices can be bent; the flexible crystalline silicon battery slices are produced by China Power 48 Optoelectronics Co., Ltd. Flexible 156*156 single and polycrystalline cells are laser cut into 156*40 specifications.

[0021] The thickness of the transparent mask layer 1 is 20 microns to 100 microns. The thickness of the hot melt adhesive film...

Abstract

The invention belongs to the field of cell modules and particularly relates to a flexible crystalline silicon solar cell module. The module is composed of a transparent surface film layer (1), one hot-melt adhesive film layer (2), a crystalline silicon cell layer (3), another hot-melt adhesive film layer (2) and a back film layer (4) in sequence from top to bottom, wherein the transparent surface film layer (1) is an ETFE layer, each hot-melt adhesive film layer (2) is an EVA layer, and the back film layer (4) is a PVDF layer. Because traditional tempered glass is replaced by flexible materials for packaging of the cell module, a crystalline silicon cell becomes flexible, bendable and the like, and the cell module is wider in application range.

Description

technical field [0001] The invention belongs to the field of solar components, and in particular relates to a flexible crystalline silicon solar cell component. Background technique [0002] In the current field of application of photovoltaic technology, especially solar cell components used in photovoltaic power generation, cell components encapsulated by tempered glass, EVA, crystalline silicon cells, and PET back film are commonly used. Due to the limitation of the preparation process, this kind of component results in large weight and volume, high production cost, and poor flexibility. With the continuous expansion of the use of emerging renewable energy, mainly solar energy, there are limitations in the application of traditional components encapsulated in tempered glass. For example, in the field of photovoltaic and building integration (BIPV), when the roof and building surfaces are uneven, defects such as volume, weight and softness of traditional solar modules are ...
