Driven by the booming development of the photovoltaic industry, the market demand for texturing additives continues to rise

Texturing additive refers to a chemical additive added during the texturing process of monocrystalline silicon solar cells that is beneficial to the reaction results and product performance. Texturing is an important process in the production of silicon solar cells. It refers to using the anisotropic corrosion characteristics of silicon to carve a pyramid-like or honeycomb-like structure on the surface, thereby increasing the surface area of ​​the cell, reducing light reflectivity, and improving silicon The purpose of light absorption performance of the film. The texturing additive contains surfactants, which can greatly improve the wettability of the texturing liquid and the silicon wafer surface, thereby improving the stability of the texturing process.

Currently, driven by the vigorous development of the domestic photovoltaic industry, some domestic companies have mastered the production process of monocrystalline solar cells, and the output of monocrystalline cells has been steadily increased. Texturing additives are one of the key chemical additives in the production of monocrystalline cells, and their market demand is rising rapidly. In 2022, my country’s monocrystalline cell production has exceeded 190GW. Against this background, according to the “2023-2028 Production Plan” released by the Industrial Research Center The “In-depth Market Research and Investment Prospects Forecast Analysis Report on the Textile Additive Industry” shows that my country’s texturing additive market demand will exceed 17 million liters in 2022.
