New breakthroughs in Jiangxi's photovoltaic industry

The photovoltaic industry is generally considered to be the core flash point of the new energy revolution and is also one of the four “100 billion industries” that our city has focused on building. Yesterday morning, the world's first double-wire, double-junction, large-area silicon-based high-efficiency thin-film solar cell project was invested and built by Jiangxi Savy Best Solar Energy Technology Co., Ltd., and a large-scale mass production ceremony was held in Nanchang High-tech Zone. This is the 8.5 generation thin film solar cell project with the highest level of technology, the largest scale and the most advanced technology in the world.

Vice Governor Hong Lihe attended the ceremony and announced that the project will be put into production. Deputy Secretary-General of the Provincial Government Hu Shizhong and other leaders attended the meeting. Chen Junqing, deputy secretary of the municipal party committee and acting mayor, made a speech.

Produce the world's largest monolithic thin-film solar cell

"We have introduced the world's leading solar equipment suppliers' technical equipment and produced 5.7 square meters of silicon-based thin-film solar cells, which is the largest monolithic thin-film solar cell in the world." Peng Xiaofeng, Chairman of LDK Solar Technology Co., Ltd., LDK Solar Introduction, thin film batteries are the second generation of solar cell technology, and the first generation of crystalline silicon cells is the most important photovoltaic battery varieties.

Peng Xiaofeng said: "At present, we have reached a stable conversion rate of 8.5%, which is in line with the conversion level of Sharp and other world-class film makers. We will increase the conversion rate to 9% within two months."

Annual sales revenue will reach 2 billion U.S. dollars

“Silicon-based solar thin-film batteries can be combined with building roofs, corridors, and glass curtains to generate electricity. Not only beautifying the environment but also replacing building materials.” Peng Xiaofeng said that silicon-based thin-film batteries are rich in raw materials, and the products are non-toxic and non-polluting. Low energy consumption, light weight, low process cost, low cost and strong low light application are very suitable for the construction of large-scale photovoltaic power plants and have become the mainstream of thin film battery development.

Peng Xiaofeng stated that at present, Jiangxi Levi BEST has signed purchase orders for 200 megawatts of thin-film solar cells with customers in the United States, Germany, and Spain.

The reporter learned that the first phase of the thin-film solar cell project has completed the basic construction, and the two production lines have now been officially put into production. After the first phase of the project is fully put into production, it will achieve a production capacity of 130 megawatts and a planned production capacity of 1,000 megawatts. According to the current market price, the estimated annual sales revenue will reach 2 billion US dollars.

It is estimated that by 2015, PV level will be used to access the Internet.

Among various clean energy sources, the photovoltaic industry has a higher cost relative to wind energy and water energy. At present, the world's advanced thin-film solar cell production costs about 1 US dollar / watt.

After the full capacity of 1,000MW of the LDK BEST thin-film battery project is realized, the technical cost is only 40%-50% of the polycrystalline silicon and single-crystal silicon cells, and the power consumption is reduced. The large-scale production will reduce the cost to 0.6-0.7 US$/ Tile level.

“The commercialization of thin-film batteries will achieve rapid expansion and popularity in the market.” Peng Xiaofeng optimistically believes that by 2015, the cost of photovoltaic power generation will reach 0.6 yuan/kWh, which can reach the most important goal of the photovoltaic industry. - Cheap Internet access.
