my country’s photovoltaic power generation installed capacity continues to expand, which is good for the development of the photovoltaic film industry

Photovoltaic adhesive film, also known as photovoltaic cell encapsulating adhesive film and photovoltaic EVA adhesive film, is a thermosetting adhesive film used for encapsulating photovoltaic cell components. Photovoltaic adhesive film has the advantages of good durability, high adhesion, and easy storage, and can protect photovoltaic cells. According to different materials, photovoltaic films are generally divided into two categories: EVA film and POE film. EVA film includes white EVA film and transparent EVA film; POE film includes co-extruded POE film and ordinary POE film.

The main raw materials of photovoltaic film are EVA resin and POE resin. EVA resin has the advantages of corrosion resistance, impact resistance, heat resistance, etc., and is widely used in various optical products and battery components. In 2021, my country’s EVA resin output reached 1.012 million tons, a year-on-year increase of 27.6%. POE resin has the dual properties of rubber and plastic and is mainly used to manufacture N-type bifacial battery packaging films. In recent years, thanks to the abundant supply of raw materials, my country’s photovoltaic film production capacity has expanded rapidly and has become the world’s largest photovoltaic film producer. According to the “2022-2027 China Photovoltaic Film Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center , my country’s photovoltaic film production capacity will reach 3.12 billion square meters in 2021, a year-on-year increase of 47.6%.

In terms of market segments, EVA film is the mainstream product of photovoltaic film, accounting for 80% of the market. EVA film uses EVA resin as its main raw material and has the characteristics of high light transmittance and low melting point. White EVA film adds white fillers such as zirconium oxide and titanium dioxide to the transparent EVA film preparation process to improve the light reflectivity and UV aging resistance of the EVA film. At present, white EVA film has gradually replaced transparent EVA film and has been widely used in photovoltaic single glass module packaging.

The field of photovoltaic power generation is the largest demand end for photovoltaic film. In recent years, as one of the new power generation methods, the prosperity of the photovoltaic power generation industry has continued to increase. According to statistics from the National Energy Administration, my country’s photovoltaic power generation installed capacity ranks first in the world in 2021, with the installed photovoltaic power generation capacity reaching 310 million kilowatts, a year-on-year increase of 20.9%. Benefiting from the rapid development of downstream industries, my country’s photovoltaic film market demand continues to grow. In 2021, my country’s photovoltaic film demand will reach 290 million square meters.

my country’s photovoltaic film manufacturers are mainly concentrated in Zhejiang, Guangdong and Jiangsu, including Zhejiang Oriental Risheng New Energy Co., Ltd., Hangzhou Foster Applied Materials Co., Ltd., and Suzhou Saiwu Applied Technology Co., Ltd. Currently, Foster ranks in the leading position in my country’s photovoltaic film industry, with a market share of 60.0%.

Industry analysts said that as an important material for packaging photovoltaic cell modules, photovoltaic adhesive film has excellent performance. Driven by national policies, my country’s photovoltaic power generation installed capacity will continue to grow, which will provide impetus for the development of the photovoltaic film industry. my country is the world’s largest producer and consumer of photovoltaic films. Driven by the technological innovation of local companies, photovoltaic films will gain broad market prospects.
