Reinforced solar cell module and making method thereof

Abstract

The invention relates to a solar cell module, in particular to a reinforced solar cell module. The reinforced solar cell module comprises toughened glass, a solar cell film and a back plate, wherein packaging materials EVA (Ethylene-vinyl Acetate Copolymer) are respectively arranged between the toughened glass and the solar cell film and between the back plate and the solar cell film; a reinforcing part is arranged on the external side of the back plate; and the back plate is combined together with the reinforcing part by heat conducting silica gel. The invention also relates to a making method of the reinforced solar cell module, which comprises six steps of cell film front-face welding, cell film back-face series welding, laying, laminating, laminated piece reinforcing and framing. The reinforced solar cell module is finally obtained by using the making process. Because the back of the module is additionally provided with a reinforcing part having a supporting reinforcing effect, the bending phenomenon of the module is obviously improved and the strength of the module is also enhanced. In addition, because the reinforcing part is provided with good heat radiation property, the normal power output of the module is assured.

Description

technical field [0001] The invention relates to a solar cell assembly, especially a reinforced solar cell assembly. The invention also relates to a method of making the reinforced solar module. It belongs to the field of solar energy technology. Background technique [0002] Traditional fuel energy is decreasing day by day, and the damage to the environment is becoming more and more prominent. According to statistics, there are still 2 billion people in the world who do not have normal energy supply. At this time, the whole world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. Among them, solar energy has become the focus of people's attention due to its unique advantages. Abundant solar radiation energy is an important energy source, which is inexhaustible, inexhaustible, cheap and pollution-free. [0003] One of the most widely used applications of solar...

AI Technical Summary

Problems solved by technology

In order to make a single component output more power, the area of ​​the component must become larger and larger. When the area of ​​the component becomes larger, its own weight will cause a large bending of the component. When the bending is too large, there will be May cause cell rupture

The function of the backplane is mainly insulation and waterproof, but because of its soft material, it cannot support the components well and is easily scratched; while the aluminum alloy frame can also support and protect the components to a certain extent, but With the increase of component area and weight, component bending cannot be avoided

On the other hand, the temperature has a great influence on the components. When sunlight shines on the components, part of the energy is converted into electrical energy, and part of the energy is converted into thermal energy, which will cause the temperature of the components to be too high and the output of the components power reduction

However, the traditional packaging method of components cannot conduct the heat generated by the components well, which also affects the power output of the components.
