Explain the current status and development trend of solar cell manufacturing equipment

The status quo and development trend of solar cell manufacturing equipment. Solar energy has become an indispensable energy-saving energy source for modern society. Therefore, this article will take you to analyze the status quo and development prospects of solar cell manufacturing equipment from international to domestic. Take the largest, most consuming, and most critical crystalline silicon solar cell manufacturing equipment in the market as an example: German, Italian, European equipment manufacturers, Japan, and American equipment manufacturers represent the highest technological level of related equipment in the world today, and its technical characteristics For high capacity and high automation, the initial 103mm*103mm, 125mm*125mm silicon has developed to the current mainstream 156mmx156mm silicon wafers. In the next two years, 210mmx120mm silicon wafers will become thinner and thinner. Micron, 270 microns, 210 microns, 180 microns, silicon technology. In particular, Germany has successfully launched the world's most advanced automatic production line equipment for 210mm×210mm square silicon wafers with almost no manual intervention. The production capacity of a typical large-scale production line in the world has risen from a few megawatts per production line five years ago to 25 megawatts, megawatts, or even 50 megawatts, such as a large-scale automatic flat-panel PECVD equipment produced by a German company. my country's research on solar cells started in 1958. In the late 80s of the last century, a number of solar cell production lines have been introduced in China, which has increased the production capacity of solar cells in my country from a few hundred kilowatts of the original three small factories to 6. The plant’s 4.5MW, this output lasted until 2002, and the output was only about 2MW. China's total solar cell output reached 139MW in 2005, up from 179 in 2004. It is expected that 2006 will continue to maintain a high rise. In 2005, the sales volume of solar panels in my country increased from 300 MW in 2004 to 37.5 MW, an increase of 136 MW. It is expected that there will be a substantial increase in 2006. There is a large number of new solar cell and module production that should be relatively, and it is also rising at a high speed. China's solar equipment market has been in the new standard of solar cell production lines in China since 2003 and ended in December 2005 in just three years, 25mw/piece, Article 17 The installed capacity of nearly 450 kilowatts of solar power generation is about 100 production capacity in 2002. According to the average investment of 50 million yuan, the equipment market for each line of equipment is as high as 850 million yuan. If it is included to solve the shortage of silicon wafers Production equipment is used to purchase materials, such as polysilicon ingot furnaces, single crystal furnaces, cutting machines and other wire saws. The domestic market for investment-related equipment will exceed 1.2 billion yuan. About one-third of the total market has been saved by domestic equipment for many years. Countries with a foreign exchange income of 100 million U.S. dollars saved nearly 800 million yuan in investment for users. In 2005, about 330 sets of related equipment were sold and nearly 250 million yuan was sold. Some equipment, such as single crystal furnaces, are exported to markets such as Japan. The purpose of developing solar cell manufacturing equipment is to improve the final product quality, photoelectric conversion efficiency and production efficiency of the entire production line, while reducing production costs. Therefore, the technical development of equipment in the future will always focus on the following aspects: 1. Improve the automation level of a single machine, increase the volume of batch loading, and improve the production efficiency of a single machine. 2. Automatic transmission of manipulators between equipments, online inspection, improve the production efficiency of the whole line, reduce manual intervention and reduce the fragment rate. 3. Transform more advanced technology into equipment: further improve the photoelectric conversion efficiency of solar cells and reduce the cost per watt. 4. Further development is suitable for large sizes: from the initial 103 mm × 103 mm and 125 mm × 125 mm silicon wafers to the current mainstream 156 mm × 156 mm silicon wafers, and the future 210 mm × 210 mm silicon wafers, thin silicon wafers Process technology equipment: 300×m×270m, 240×m×210m×180m, 150×m, etc. The current mainstream silicon wafer thickness is 210nm-240nm, which saves the cost of silicon materials.
