CITIC Construction Investment pointed out that looking ahead to 2023, as the efficiency of perovskite battery laboratories, test lines, and mass production lines continues to improve, and the stability of perovskite components is certified by authorities, the industry will usher in opportunities to accelerate development. At the same time, leading players in the perovskite industry are expected to launch GW grade perovskite equipment tenders in 2023, creating a strong catalyst for the equipment industry. Technological innovation, equipment first, we focus on recommending perovskite equipment suppliers. Perovskite equipment mainly includes coating equipment, laser equipment, laminating equipment, etc. Among them, coating equipment has a high competitive barrier. How to achieve uniform coating on a large area is a difficult technical key point. It is recommended to focus on coating equipment suppliers Jingshan Light Machinery, Jiejia Weichuang, Maiwei Shares, OLED, AOL Electronics, etc.; compared to different coating scheme choices, the application of laser equipment is highly certain. It is recommended that laser suppliers that cooperate closely with downstream manufacturers, laser suppliers such as Dafu Laser, Drone Laser, JPT, Diller, etc. Lasers, etc.; packaging equipment suppliers recommend Jingshan Light Machinery.
