Abstract

The invention discloses a solar battery backboard material with high weather resistance and a preparation method thereof. The solar battery backboard material comprises the following components in parts by weight: 45-50 parts of PET, 25-30 parts of PETG, 1-2 parts of glass micro-powder, 10-15 parts of a nano-material, 0.8-1.5 parts of an ultraviolet absorbent, 2.5-3 parts of a light stabilizing agent GW-540, 1-2 parts of an anti-aging agent, 0.6-1 part of antioxidant and 3-4 parts of a stabilizing agent. The solar battery backboard material with high weather resistance prepared by the invention is high and reliable in electrical insulation property, oxygen barrier performance, water barrier property and anti-aging property, so that the high weather resistance is represented, and various types of bad weather conditions can be endured. The preparation method is simple in process, and low in cost; the service life of the solar battery can be prolonged.

Description

technical field [0001] The invention relates to the field of photoelectric materials, in particular to a high weather resistance solar cell backboard material and a preparation method. Background technique [0002] Traditional energy such as oil, coal and other non-renewable resources are gradually being consumed. Energy issues have increasingly become a bottleneck restricting the social and economic development of countries around the world. There are still 2 billion people in the world who do not have normal energy supply. Therefore, finding new energy has become a top priority. Solar energy, as an inexhaustible, non-polluting green energy, has been valued by various countries. Solar power generation, as the most important application form of solar energy, has been used by most countries and has been vigorously promoted. Solar power generation uses the quantum effect principle of silicon and other semiconductors to directly convert the visible light of the sun into electri...
