Abstract

The invention discloses a frameless crystalline silicon battery completely anti-PID lightweight assembly, including: a front glass, a cell, a back plate and a junction box, the battery is located between the front glass and the back plate; the front The plate glass is photovoltaic ultra-clear patterned glass with a thickness of 4.0-5.0 mm, and the surface of the front glass is coated with nano-titanium dioxide film. There are packaging material layers between them, the packaging material layer is polyolefin, the junction box is electrically connected to the battery sheet, and a wavelength conversion agent is mixed in the packaging material layer, and the wavelength conversion agent can convert invalid or low The effective wavelength of sunlight is shifted to the effective wavelength. The frameless crystalline silicon battery of the present invention is completely anti-PID, and the light-weight component abandons the aluminum frame, and the component can meet the load requirement of 5400pa without framing; and the component is completely resistant to PID, and reduces the weight of the component, reduces the thickness of the component, and reduces the manufacturing cost .

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 board. Background technique

[0002] Crystalline silicon is divided into single crystal silicon, polycrystalline silicon, and amorphous silicon. Among them, monocrystalline silicon solar cells are currently the fastest developed type of solar cells. Its structure and production process have been finalized, and its 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 its grounded metal frame will cause the continuous attenuation of the photovoltaic performance of the module. There are many mechanisms causing such attenuation. For example, under the action...
