There are many types of photosensitive adhesives (photoresists), and the photovoltaic field is its emerging demand end.

Photosensitive adhesive, also known as photoresist and photosensitive latex, is a photosensitive material made by linking photosensitive resin with polymer polymer. Photosensitive adhesive has the advantages of low operating cost, long service life, good wear resistance, and simple process. It has broad application prospects in many fields such as photovoltaics, printing, electronics and electrical.

There are many types of photosensitive adhesives. According to different properties, photosensitive adhesives can be divided into water-resistant photosensitive adhesives and solvent-resistant photosensitive adhesives; according to different production and use methods, they can be divided into two-liquid photosensitive adhesives and single-liquid photosensitive adhesives; according to their main components, they can be divided into Diazo photosensitive adhesive and non-diazo photosensitive adhesive. Diazo photosensitive adhesive, also known as odd-paste photosensitive adhesive, has the characteristics of good solvent resistance, good water resistance, and fast photosensitive speed. It is widely used in the field of precision printing and is the mainstream product in my country’s photosensitive adhesive market.

The main base materials of photosensitive adhesive are nylon, gelatin, polyvinyl alcohol (PVA), polyacrylic acid (PAA), phenolic resin, silver salt, etc. Silver salt is the core raw material of photosensitive adhesive, including silver chloride, silver bromide, silver halide and silver iodide, etc., which can effectively increase the photosensitive effect of photosensitive adhesive; gelatin, polyvinyl alcohol (PVA), polyacrylic acid (PAA), etc. are photosensitive adhesives. Colloidal material used in the production process, which can increase the transparency and adhesion of photosensitive adhesive. The wide source and sufficient supply of raw materials provide favorable conditions for the development of the photosensitive adhesive industry.

According to the “2023-2028 China Photosensitive Adhesive (Photoresist) Industry Market In-depth Research and Development Prospects Forecast Report》 shows that photosensitive adhesive has broad application prospects in many fields such as photovoltaics, printing, electronics and electrical, and the photovoltaic field is its emerging demand side. Photovoltaic photosensitive adhesive can be used as a mask material in the photovoltaic copper plating process. In recent years, with the support of national policies, the development of my country’s photovoltaic industry has accelerated. According to data released by the National Energy Administration, my country’s installed photovoltaic power generation capacity will reach 390 million kilowatts in 2022, a year-on-year increase of 28.1%. As the market demand for photovoltaic photosensitive adhesive grows, the prosperity of my country’s photosensitive adhesive industry will increase.

The world’s leading photosensitive adhesive companies include German KIWO, American Chromaline, British Autotype, American Ulano, etc. Compared with overseas developed countries, my country’s photosensitive adhesive industry started late, and high-end products mainly rely on imports. Guangxin Materials is a representative enterprise of photovoltaic photosensitive adhesive in my country, and its products are expected to be supplied in batches to photovoltaic cell companies in the future.

Industry analysts said that photosensitive adhesive has excellent performance and is widely used in many fields. In the future, as the prosperity of my country’s photovoltaic industry continues to increase, its Market demand will grow further. There are extremely rich types of photosensitive adhesives, and diazo series photosensitive adhesives are the mainstream products. It is expected that in the future, companies with large-scale production capabilities of high-performance photosensitive adhesive will occupy a larger space in my country’s market.
