Frameless photovoltaic module and solar panel

Abstract

The invention discloses a frameless photovoltaic module and a solar panel. The frameless photovoltaic module comprises front panel glass, cell slices, a backplane and a junction box, wherein the cell slices are located between the front panel glass and the backplane; the front panel glass is photovoltaic ultra white figured glass with a thickness of 4.0 to 5.0 mm; the ultra white figured glass is internally provided with uniformly-distributed micron bubbles and a conversion material; packaging material layers are arranged between the cell slices and the front panel glass and between the cell slices and the backplane; each packaging material layer is internally provided with a lower conversion material and an upper conversion material; the packaging material layer is polyolefin; and the junction box is electrically connected with the cell slices. The frameless photovoltaic module has the advantages that the water vapor permeability is low; the micron bubbles are introduced to enable the journey of light passing the front panel to be increased, and the light utilization rate is improved through match with the conversion material existing in the glass.

Description

technical field [0001] The invention relates to a crystalline silicon photovoltaic module, in particular to a frameless photovoltaic 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 of the above-mentioned high voltage, the ion m...

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
