Abstract

The invention discloses a solar battery board composite resin film material and a preparation method thereof. The solar battery board composite resin film material consists of 10-40 parts by mass of ananoparticle material, 30-60 parts by mass of a transparent polyurethane resin and 10-30 parts by mass of a crosslinking agent. The preparation method comprises the following steps: premixing the 10-40 parts by mass of the nanoparticle material, 30-60 parts by mass of the transparent polyurethane resin and 10-30 parts by mass of the crosslinking agent, conducting crosslinking curing through pressurizing and heating, and conducting cutting into an appropriate size, so as to obtain a product, wherein the nanoparticle material is, but not limited to, a monofilament nanofiber. The solar battery board composite resin film material disclosed by the invention can be used as a packaging material of glass, and defects that conventional solar battery component glass is liable to crack, large in mass, poor in ultraviolet resistance, aging resistance and impact resistance, not fireproof, and the like, can be overcome.

Description

technical field [0001] The invention relates to the technical field of photovoltaic applications, in particular to a composite resin film material for a solar panel and a preparation method thereof. Background technique [0002] With the increasing progress of photovoltaic industry technology, the efficiency of solar cell components is constantly rising, the production process is constantly improving, and the production cost is constantly falling. Solar energy is more and more popular among people. [0003] The main component of a solar photovoltaic cell module is a solar cell. Since solar cells cannot be directly exposed to natural conditions such as sunlight and rain, in order to realize the practical application of solar power generation, they must be protectively packaged and formed into battery components. [0004] At present, solar cells generally use EVA (ethylene-vinyl acetate copolymer)-glass as packaging material. Although this packaging can meet the basic require...
