Abstract

The invention discloses a POE adhesive film with high electrical strength and electrical tracking resistance. The POE adhesive film comprises the following raw materials by weight: 70 to 90 parts of ethylene-octene copolymer modified particles and 10 to 30 parts of a functional masterbatch, wherein the functional masterbatch comprises the following raw materials by weight: 70 to 90 parts of an ethylene-vinyl acetate copolymer, 10 to 30 parts of an ethylene-methyl methacrylate copolymer, 0.1 to 5.0 parts of a photoinitiator and 0.5 to 3.0 parts of a stabilizer; and the stabilizer is a benzil stabilizer. The invention also discloses a preparation method for the above-mentioned POE adhesive film. On the basis that high transmittance and adhesion properties of the adhesive film are maintained,the POE adhesive film provided by the invention has high electrical strength and electrical tracking index resistance, is applied to packaging of a photovoltaic assembly, can effectively improve theelectrical strength and electrical tracking index resistance of the photovoltaic assembly, avoids large drop or failure of the power of the photovoltaic assembly in the process of photoelectric conversion, thereby greatly reducing hot spot effect and the phenomenon of electric breakdown damage or electrical tracking damage.

Description

technical field

[0001] The invention relates to the technical field of solar cells, in particular to a POE adhesive film with high electric strength and resistance to electrical traces and a preparation method. Background technique

[0002] With the continuous development of solar energy utilization technology, solar energy is widely used as a green energy source. As a unit carrier for utilizing solar energy, solar photovoltaic modules can be combined into large-scale photovoltaic power stations or household distributed small power stations to continuously provide electricity for thousands of households.

[0003] However, during the long-term use of photovoltaic modules after they are installed and connected to the grid, they are constantly subjected to natural environments including high temperature and high humidity aging, thermal oxygen aging, high and low temperature aging, ultraviolet aging, and foreign matter pollution in the working state of absorbing light energy and ...
