With the continuous advancement of perovskite solar cell technology, perovskite coating equipment will also usher in new development opportunities.

Market Status: The high-growth track is beginning to take shape

Since the introduction of perovskite solar cells in 2009, their energy conversion efficiency has rapidly improved from the initial 3.8% to over 25% currently, with potential for further improvement. This material not only boasts excellent photoelectric conversion performance but also offers advantages such as low cost and ease of preparation, making it a rising star in the photovoltaic industry.

By 2025, the perovskite photovoltaic industry will enter a period of accelerated development. With technological maturity and policy support, perovskite cells, leveraging advantages such as high efficiency, low cost, and lightweight design, are gradually moving from laboratories to large-scale production. It is predicted that by 2025, the global perovskite module market will reach 3.75 billion yuan, and is expected to exceed 95 billion yuan by 2030, with a compound annual growth rate (CAGR) as high as 128%.

Coating equipment, as a key link in perovskite cell production, accounts for 30% of the total equipment investment cost. Currently, the market size of China's perovskite coating machines is about 1 billion yuan/GW, but with process optimization and mass production cost reduction, equipment investment costs are expected to drop to 500 million yuan/GW by 2030, with market space continuing to expand.

Perovskite coating equipment: the new engine of the photovoltaic industry

In the preparation of perovskite solar cells, the coating process is one of the key steps. The quality of the coating process directly affects the cell's uniformity, stability, and final photoelectric conversion efficiency. Therefore, efficient and precise coating equipment is crucial for the production of perovskite solar cells. The main points include the following:

Uniformity: The coating process must ensure the uniform distribution of perovskite material on the substrate. The uniformity of the film directly affects the photoelectric conversion efficiency and stability of the cell. Uneven films cause uneven distribution of the electric field inside the battery, affecting the transport of electrons and holes, thereby reducing the battery's conversion efficiency.

Precise control: The coating process requires precise control of the film's thickness. The thickness of the film has a significant impact on battery performance. Films that are too thick or too thin can both lead to degraded battery performance. Therefore, the coating process requires precise control of the coating thickness to achieve optimal photoelectric conversion efficiency.

Stable discharge rate stability of the liquid supply system: The stable output and output accuracy of the liquid supply pump also affect coating uniformity. Therefore, the motor selection for the supply pump is very important. The motor drive type must at least be a servo motor. Currently, Siemens servo motors in the coating industry can meet the perovskite process precision requirements and can also be selected as superior types compared to servo motors;

Material stability: Perovskite materials are sensitive to environmental conditions and are easily affected by humidity and oxygen. The coating process must be carried out in a strictly controlled environment to prevent material decomposition or deterioration during application.

Cost-effectiveness: The low cost of perovskite solar cells is one of their main advantages. Optimizing the coating process can reduce material consumption and production costs, improve production efficiency, and further lower the overall cost of perovskite solar cells.

Challenges and opportunities coexist

As a new engine in the photovoltaic industry, the development of perovskite coating equipment not only affects the production efficiency and quality of perovskite solar cells but also impacts the future of the entire photovoltaic industry. In the future, perovskite coating equipment will become more intelligent and automated to meet the needs of large-scale production. At the same time, the performance of the equipment will be further enhanced to meet the production requirements of higher-efficiency perovskite solar cells.

In terms of material compatibility, perovskite materials need to be compatible with substrates and other layer materials to ensure the overall performance of the battery. The coating process needs to adapt to different material systems to ensure material stability and activity; In terms of environmental control, strict control of environmental conditions such as temperature, humidity, and oxygen content during coating is necessary to prevent decomposition of perovskite materials; In terms of equipment precision requirements, coating equipment needs high-precision coating heads and control systems to achieve uniform coating and thickness control of the film.

2025 will be a key turning point for perovskite industrialization. With technological breakthroughs and capacity release by domestic equipment manufacturers, China is expected to dominate the global perovskite equipment market.
