Abstract

The invention relates to a light-penetrable cover board for stockbreeding equipment and a preparation method thereof, wherein the light-penetrable cover board and the preparation method belong to the technical field of stockbreeding equipment. The preparation method of the light-penetrable cover board comprises the steps of firstly preparing a silicon heterojunction solar cell; packaging the silicon heterojunction solar cell for preparing a silicon heterojunction solar cell assembly; and finally closely connecting the silicon heterojunction solar cell assemblies for forming the light-penetrable cover board for the stockbreeding equipment. Compared with prior art, the light-penetrable cover board and the preparation method thereof are advantageous in that the light-penetrable cover board has excellent lighting performance and furthermore can supply electric energy to the stockbreeding equipment.

Description

technical field [0001] The invention relates to the technical field of animal husbandry equipment, in particular to a light-transmitting cover plate used for animal husbandry equipment and a preparation method thereof. Background technique [0002] The development of breeding has played a positive role in the growth of the number of livestock and poultry products in my country. Among them, the poultry breeding industry has rapidly developed into the darling of my country's agriculture and animal husbandry due to its advantages of high efficiency and low cost. However, the existing cover panels for livestock breeding equipment are often transparent glass panels, transparent resin panels or conventional solar photovoltaic tiles, that is, the existing cover panels for livestock breeding equipment or the lighting performance can be but cannot be used for livestock breeding. Farming equipment provides electric energy, or it can provide electric energy for livestock breeding equip...
