Problems solved by technology

However, for special electrical components such as solar modules, it not only needs to be safe but also needs to have outdoor reliability of up to 25 years, so the reduction of power generation costs from the raw and auxiliary materials alone has reached the limit
It can be seen that based on the consideration of long-term reliability, the decline space of raw and auxiliary materials in the future will become narrower and narrower

Abstract

The invention discloses a power gain type solar backboard material. The backboard material is composed of a gain layer, a base body layer and a weather-proof layer. The obtained backboard material has the good visible light reflectance, and meanwhile has the good water vapor barrier property, mechanical performance, dimensional stability and long-term weather resistance. The preparation technology is simple, convenient and stable in product performance, can have obvious gain for electricity generation power of a solar assembly, can effectively decrease the cost per kw h of a solar power station, can meet the requirement of long-term insulativity and weather resistance of the solar assembly in power station systems of different scales, and is excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the field of photovoltaic encapsulation materials, and relates to a power-gaining solar backboard material. Background technique [0002] In recent years, with the rapid development of modernization and electrification technology, the problem of environmental pollution has become more and more widespread and more serious. This change has had a great impact on people's production, life and health. Therefore, the global demand for clean new energy is becoming more and more urgent. Among several clean new energy sources that can be applied on a large scale, such as hydropower, wind power, solar energy, biomass energy, and ocean tide energy, solar energy has attracted much attention because of its inexhaustible characteristics. The fastest growing clean new energy industry. In my country, smoggy weather caused by environmental pollution occurs frequently, and the national and local governments have also accelerated the support an...
