Embodiment 1

[0031] A flexible solar cell module, consisting of a surface layer 1, an upper ethylene-vinyl acetate copolymer layer 2, a high-strength low-iron tempered glass layer 3, a middle ethylene-vinyl acetate copolymer layer 4, a solar cell layer 5, and a lower ethylene-vinyl acetate layer The copolymer layer 6 and the back sheet layer 7 are stacked and arranged sequentially from top to bottom to form an encapsulation structure, and the surface layer 1 and the back sheet layer 7 are both transparent polyvinyl fluoride composite films.

[0032] A method for preparing the flexible solar cell module described in claim 1, the steps are:

[0033] a. At a room temperature of 25°C, place the high-strength low-iron tempered glass flat on the workbench and cover it with a high-temperature cloth;

[0034] b. Spread a layer of transparent polyvinyl fluoride composite film and an upper layer of ethylene-vinyl acetate copolymer on the high-temperature cloth in sequence;

[0035] c. Put a high-st...

Abstract

A flexible solar battery assembly consists of a surface layer, an upper ethylene-vinyl acetate copolymer layer, a high-strength low-iron toughened glass layer, an intermediate ethylene-vinyl acetate copolymer layer, a solar battery layer, a lower ethylene-vinyl acetate copolymer layer and a back plate layer, which are sequentially arranged from top to bottom in a superposition manner and are packaged together, wherein the surface layer and the back plate layer are made of a transparent poly(vinyl fluoride) composite membrane. The solar battery assembly can be bent by a certain radian according to the actual requirement to suit the places with the certain radian such as the top of a solar vehicle and skylight of cars.

Description

1. Technical field [0001] The invention belongs to the field of new energy photovoltaic power generation, and in particular relates to a flexible solar cell module 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 forms, is safe and pollution-free, and...
