Solar photovoltaic module anti-counterfeiting marking method and solar photovoltaic module with anti-counterfeiting marking function

Abstract

The invention discloses a solar photovoltaic module anti-counterfeiting marking method and a solar photovoltaic module with the anti-counterfeiting marking function. According to the anti-counterfeiting marking method, an anti-counterfeiting marking part with the anti-counterfeiting marking function is formed at any position of the junctures of adjacent layers of multiple layers of parts of the solar photovoltaic module or at any position of the front side or back side of a solar photovoltaic battery in the solar photovoltaic module through printing ink, the anti-counterfeiting marking part can display a mark under the stimulation of external conditions, and then the anti-counterfeiting marking function is achieved for the solar photovoltaic module. Meanwhile, the invention discloses the solar photovoltaic module with the anti-counterfeiting marking function. The anti-counterfeiting marking part with the anti-counterfeiting marking function is formed at any position of the junctures of adjacent layers of multiple layers of parts of the solar photovoltaic module or at any position of the front side or back side of the solar photovoltaic battery in the solar photovoltaic module through printing ink. The mark has an effective anti-counterfeiting effect, and duplication can not be achieved easily.

Description

technical field [0001] The invention belongs to the photovoltaic field, and specifically refers to a solar photovoltaic module anti-counterfeit marking method and a solar photovoltaic module with an anti-counterfeit marking function. Background technique [0002] With the continuous development of the industry, photovoltaic power generation has entered the stage of large-scale application, and the support of policies in various countries has prompted photovoltaic power generation to turn to small and medium-sized distributed applications. However, in the past few years when the industry has been booming, large, medium and small photovoltaic companies have developed too much, and the industry's production capacity has far exceeded the social consumption capacity. The resulting vicious competition has also led to changes in the relationship between supply and demand. Products have repeatedly caused incidents that damage the image of the industry, and currently there are no sys...

Problems solved by technology

The common features of these three methods are: ① There will be surface damage or performance loss. Laser ablation uses the thermal effect of laser to remove materials, causing surface lattice defects, resulting in local thinning of silicon wafers, deterioration of mechanical properties and increase of leakage current. The textured marking area has a high reflectivity, which affects the light absorption performance just like the printed metal marking; ②Due to the above reasons, the size of these three types of markings can only be produced in a limited manner, generally at the micron to millimeter level, This type of logo can be identified in battery production, but once it is combined with a scattering packaging material to become a module, it loses the ability to be clearly identified; ③ they are all based on existing specific processing equipment, not only the equipment cost is high, Moreover, the logo is easy to be copied, which loses its anti-counterfeiting effect
