Abstract

The invention discloses a high-reflective degradable mulching film. The reflective film comprises an upper protective layer, an adhesive layer, a reflective coating, a prism base layer and a lower protective layer from top to bottom. The upper surface of the lower protective layer is coated with the reflective coating. The reflective film covers the ground surface under an assembly, and accordingly the aim of reflecting sunlight which directly irradiates the ground to the back side of the two-side assembly is achieved. Adaptability between the two-side assembly and different environments is greatly improved. Materials in use are biodegradable materials, the cost is low, the degradation age limit is about 25 years, and the materials are highly matched with the service life of the assembly and do not pollute the environment. The prepared high-reflective degradable mulching film has high light reflectivity and high water vapor isolation performance, and also has outstanding advantages in the aspects of temperature use range, mechanical properties, outdoor weather resistance and the like.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a highly reflective and degradable mulch film that improves the adaptability of double-sided battery components. Background technique [0002] With the continuous development of photovoltaic technology, the improvement of ordinary solar cells has reached a bottleneck, and it is difficult to greatly improve their power generation efficiency, so relevant personnel have shifted their direction to double-sided cells. [0003] The double-sided battery module can use the reflected light from the back and the diffuse light from the surrounding environment. Under the same footprint, the double-sided battery module can have higher power generation efficiency. However, the use of double-sided battery components has great limitations. Due to the extremely low reflectivity of ordinary ground, it is difficult to use double-sided batteries in general areas. The emergence of highly reflec...
