In the last decade, the world's solar cell production has grown at an average rate of 40%. The average growth rate in the last five years was 45.4%. The average growth rate in the last three years exceeded 50%. The photovoltaic industry has become one of the fastest growing high-tech industries in the world. As a support, the equipment plays a vital role in the development of the photovoltaic industry.
High-end equipment still needs to be imported
The solar photovoltaic industry includes photovoltaic materials, photovoltaic cells, photovoltaic modules, photovoltaic devices and photovoltaic applications. Taking crystalline silicon solar cells occupying more than 95% of solar cells as an example, the industrial chain is silicon ore-metallurgical silicon (industrial silicon, 99% pure)-high-purity silicon (6N or above purity)-monocrystalline or polycrystalline-silicon Chips - batteries - components - application products, equipment is the foundation and support, running through all aspects.
In addition to the previous material purification, wafer processing and downstream component production, the most critical process is battery manufacturing, which includes cleaning, texturing, diffusion, etching, anti-reflection film preparation, electrode printing, low temperature drying, High temperature sintering, automatic testing of bifurcation, etc.
After several years of hard work, China's photovoltaic equipment enterprises have basically possessed the capacity of solar cell manufacturing equipment. Some products, such as diffusion furnaces and plasma etching machines, have begun to export a small amount, and can provide 8 kinds of 10 kinds of solar cell large production line equipment. Among them, 6 kinds (diffusion furnace, plasma etching machine, cleaning/texturing machine, quartz tube cleaning machine, low temperature drying furnace) have occupied the leading position in domestic production lines, 2 kinds (tube type PECVD, rapid sintering furnace) and Imported equipment coexists but the share is gradually increasing. Three types (automatic screen printing machine, automatic tiller, flat PECVD) are completely dependent on imports.
Laminators and solar simulators for component production are widely used in the industry.
The single crystal furnace in the silicon wafer processing equipment has occupied the absolute dominance of the domestic market with excellent cost performance and exported to Asia in batches. The multi-line cutting machine has made breakthroughs, and the polycrystalline silicon ingot furnace is just around the corner.
The key 24 pairs of rod reduction furnaces in high-purity silicon material purification equipment have also been successfully developed with the support of the national “863†program.
Domestic solar photovoltaic equipment has established a good reputation among domestic users and has been widely recognized by the industry. More and more customers have benefited from the use of domestic equipment. It can be said that China's solar photovoltaic industry has the ability to face international competition in just a few years. The weapon for rapid development lies in the fact that technology and international standards are combined with unmatched low-cost advantages, while the reasons for maintaining lower production costs are lower. In addition to the labor and operating costs, the large number of domestically produced equipment at low prices (on average, only one-third of imported equipment) has led to a significant reduction in corporate investment costs. Otherwise, 95% of the PV industry's market characteristics in Europe, America and Japan, it is difficult to imagine that domestic enterprises can compete in the international market with much higher silicon material procurement costs than similar foreign companies.
Domestic equipment has been applied in large production lines
Since 2002, the extraordinary development of Wuxi Suntech Power Company has provided a rare opportunity for equipment companies. Through cooperation with leading battery companies and the introduction of advanced technology, after many times of technology replacement and upgrading, the domestic key solar cell equipment has been applied in domestic large production lines, making China basically have the full supply capacity of solar cell manufacturing equipment.
The serious shortage of high-purity silicon materials provides an excellent opportunity for domestically produced single-crystal furnace enterprises with high quality and low price. In recent years, dozens of new single-crystal drawing enterprises have placed large orders, making domestic equipment enterprises always full. Load production status, and attracted bulk orders from Japan, South Korea and Taiwan. The hot scenes that have not been seen for so many years directly gave birth to the orders of four photovoltaic equipment manufacturers in 2006, which exceeded 100 million yuan. The momentum in 2007 is even worse than that. This is the prosperity of China's electronic equipment industry for many years. scene.
In addition, although amorphous silicon solar cells have not yet formed scale production, the growth rate has been significantly accelerated, and the corresponding amorphous silicon battery equipment has also attracted many companies to try to enter in the same way as the whole-line package equipment and process.
