The invention discloses a frameless crystal silicon cell complete anti-PID light assembly and solar panel, and the frameless crystal silicon cell complete anti-PID light assembly and solar panel comprises a front glass plate, a battery piece, a backboard and a wiring box, the battery piece is located between the front glass plate and the backboard; the front glass plate is the photovoltaic super white figured glass with thickness of 4.0-5.0mm, the packaging material layer is respectively formed between the battery piece and the front glass plate and between the battery piece and the backboard, the packaging material layer is polyolefin, the wiring box is electrically connected to the battery piece. The frameless crystal silicon cell complete anti-PID light assembly needs no aluminum frame for satisfying the loading requirement of 5400pa without frame; and the assembly is resistant to PID completely, the weight, thickness and the manufacturing cost of the assembly are reduced. The service life of the assembly is prolonged, the power attenuation of assembly during the using process is reduced, the application range of the crystal silicon assembly is expanded, and the convenience and transportability of the crystal silicon assembly are raised.

Description

Technical field [0001] The invention relates to a crystalline silicon photovoltaic module, in particular to a frameless crystalline silicon battery completely anti-PID lightweight module and battery panel. Background technique [0002] Crystalline silicon is classified into single crystal silicon, polycrystalline silicon, and amorphous silicon. Among them, the monocrystalline silicon solar cell is currently the fastest developed solar cell. Its structure and production process have been finalized, and the products have been widely used in space and on the ground. [0003] The above-mentioned crystalline silicon can be used to make crystalline silicon photovoltaic modules. Studies have shown that the high voltage between the circuit in the crystalline silicon photovoltaic module and the grounded metal frame will cause the continuous degradation of the photovoltaic performance of the module. There are many mechanisms that cause such attenuation. For example, under the action of the ...

Problems solved by technology

Conventional anti-PID (Potential Induced Degradation—Potential Induced Degradation), the module power attenuation is obvious after the module is used for 3-5 years. During the life of the module, the power attenuation is too much, and the life of the module is shortened, resulting in a significant drop in the power generation of the power station

[0005] At the same time, the weight of existing conventional crystalline silicon components is about 20kg

The weight of the component itself limits its scope of application, and cannot meet actual needs in projects such as roofs with weak load-bearing capacity

Moreover, conventional crystalline silicon components are bulky, making them inconvenient to carry and transport
