Abstract

The invention provides a novel high-thermal-conductive packaging material for a solar module. The novel high-thermal-conductive packaging material is characterized in that fillers which have outstanding thermal conductive performance and can be dispersed uniformly in an EVA (Ethylene Vinyl Acetate) adhesive film are prepared; and the PV (Photovoltaic) packaging material is composed of the following raw materials in parts by mass: 5 to 20 parts of high-performance carbon multi-walled nano-tube thermal-conductive filler (MWNT-PBV), 100 parts of ethylene vinyl acetate copolymer, 0.6 to 1.5 parts of crosslinking curing agent, 0.04 to 0.18 part of crosslinking curing accelerant, 0.1 to 0.2 part of silane coupling agent, 0.1 to 0.4 part of antioxidant, 0.1 to 0.3 part of ultraviolet absorber, and 30 to 60 parts of thermal-conductive functional powder. The prepared heat-conductive solar packaging material has outstanding adhering performance and high crosslinking density, can resist outdoor ultraviolet light aging, thermal oxidation and moisture erosion for a long time; and the heat resistance and heat dissipation properties are effectively improved, the temperature on the surface of a silicon cell can be effectively reduced, and the photovoltaic conversion efficiency is remarkably improved.

Description

technical field [0001] The invention discloses a novel high thermal conductivity solar module encapsulation material, which belongs to the solar module encapsulation polymer composite material. Background technique [0002] With the depletion of traditional fossil fuels, human beings are constantly looking for new energy alternatives. Solar energy is currently recognized as a green renewable resource. Photovoltaic (PV) power generation industry has continued to develop rapidly since the 1980s. How to effectively utilize solar energy has become a hot spot in the field of new energy technology. Both the United States and Europe have formulated the "Million Solar Roofs Plan". According to the "Renewable Energy Medium and Long-Term Development Plan" compiled by the National Development and Reform Commission, by 2020, the total capacity of photovoltaic power generation in my country will reach 25 million kilowatts. PV modules in a photovoltaic power generation system need to wi...
