Cushion pad for transfer transport of solar cell

Abstract

The invention discloses a cushion pad for the transfer transport of a solar cell. The cushion pad comprises an elastic basal slice and an elastic convex body which is arranged on the surface of the elastic basal slice and contacted with a silicon slice, the thickness of the elastic basal slice is 1.0-5.0 mm, the height of the elastic convex bodies is 0.3-1.5 mm, the diameter of the elastic convex bodies is 0.5-0.8 mm, the distribution density of the elastic convex bodies is 60-150 per square centimeter, and the shape of the elastic basal slice corresponds to the shape of the solar cell. During transfer transportation, the elastic cushion pad is positioned under the tandem of the solar cell, and the elastic convex bodies are arranged on the contact surface of the elastic basal slice and the silicon slice uniformly, so that the impact force borne by the solar cell is decomposed by the elastic convex bodies on the cushion pad even when a transfer transportation vehicle is impacted by certain force, and the breakage rate of the impacted solar cell is greatly reduced.

Description

Technical field: [0001] The invention relates to a crystalline silicon solar cell, in particular to a transportation shockproof device for the solar cell. Background technique: [0002] According to the forecast of the World Energy Organization (IEA), the European Joint Research Center, and the European Photovoltaic Industry Association, the world's photovoltaic power generation will account for 1% of the total electricity in 2020, and by 2040, photovoltaic power generation will account for 20% of the global power generation. For decades, the growth rate of the global photovoltaic industry will be as high as 25%-30%. It can be predicted that in the middle of the 21st century, solar photovoltaic power generation will become one of the basic energy sources for human beings and occupy a certain position in the world's energy composition. At present, the production of solar cells is mainly based on crystalline silicon solar cells, accounting for 83.8% of the world's total outpu...

Problems solved by technology

[0003] Due to the high brittleness of crystalline silicon wafers, they are easily broken. In the production process of solar crystalline silicon wafers, crystalline silicon wafers have to go through multiple processing procedures. During the production turnover process, crystalline silicon wafers are stacked together. , On the one hand, when the process turnover car is impacted during the promotion process, it is easy to cause silicon chips to break, which is one of the factors with the highest damage rate in the production process of solar cells; on the other hand, the bottom piece of the transfer box The crystalline silicon wafer is easily damaged when it is taken out because it is adsorbed by the bottom of the box
