The industrialization process of photovoltaic copper electroplating process continues to accelerate, and the photovoltaic photosensitive adhesive market has good development prospects.

Photosensitive glue, also known as photosensitive latex, refers to a polymer with special photosensitivity that can undergo photochemical reactions under light irradiation of a certain wavelength, causing changes in molecular structure, thereby achieving the recording and conversion of optical information. Photovoltaic photosensitive adhesive refers to the photosensitive adhesive used in the photovoltaic field, specifically the photosensitive adhesive used in the patterning process of photovoltaic copper electroplating process.

Photovoltaic copper electroplating refers to an electrode preparation process that uses electroplating to deposit metallic copper on a transparent conductive film (TCO). Electroplated copper grid lines are used instead of screen-printed silver grid lines to achieve the purpose of reducing silver paste consumption. Currently, this Technology has become the main path for photovoltaic cost reduction and efficiency improvement, and has broad application prospects in the field of HJT cell manufacturing. Photovoltaic copper electroplating includes four major links: seed layer deposition, patterning, electroplating, and post-processing. Patterning is the key link. The main steps include seed layer plating, mask making/spraying photosensitive glue, exposure and development, etc.

Photovoltaic photosensitive adhesive is the photosensitive material required in the mask making/spraying photosensitive adhesive step in the photovoltaic copper electroplating patterning process. Its industry development is closely related to the development of the photovoltaic copper electroplating industry. At present, the domestic photovoltaic copper electroplating industry is in the development stage from 0 to 1, and the number of companies in this field is constantly increasing, such as State Power Investment Corporation, Jinshi Energy, Haiyuan Composite Materials, etc. It is expected that by 2024, its equipment is expected to enter mass production stage; it is estimated that by 2030, its equipment market space is expected to exceed 27 billion yuan.

According to the “2023-2028 Photovoltaic Photosensitive Adhesive Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center It shows that benefiting from the gradual increase in the cost reduction and efficiency increase trend in the domestic photovoltaic industry, the industrialization process of photovoltaic copper electroplating continues to accelerate, which in turn brings broad development space to the photovoltaic photosensitive adhesive market.

Photovoltaic photosensitive adhesive has broad application prospects, but as a new type of photosensitive material, its industry is still in the early stages of industrialization, and the number of companies entering the market is relatively small. At present, Jiangsu Guangxin Photosensitive New Materials Co., Ltd. (Guangxin Materials) has been deployed in the field of photovoltaic photosensitive adhesive research and development in China. The company has sufficient experience and technical reserves in photosensitive materials. Based on this, the research and development progress of photovoltaic photosensitive adhesive is advancing in an orderly manner. . As of June 2023, Guangxin Materials’ photovoltaic photosensitive adhesive products have multiple sets of technical routes and are being developed and tested with a number of downstream leading battery component companies and equipment companies. In the future, as the research and development process continues to accelerate, the company is expected to be the leader in domestic photovoltaic photosensitive adhesive products. The glue market occupies a first-mover advantageous position, and the industry has huge development potential.

Industry analysts said that photovoltaic photosensitive adhesive is the key to the patterning process in the photovoltaic copper electroplating process Photosensitive materials, the current continuous acceleration of the industrialization process of domestic photovoltaic copper electroplating has brought broad demand space to its market, and the industry development prospects are good. However, photovoltaic photosensitive adhesive is a new type of material in the photovoltaic field. The industry is still in its early development stage. Currently, there are few domestic companies. Guangxin Materials is the one with the fastest R&D process and is expected to occupy a first-mover advantage in the market in the future.
