As the winner of the first batch of overseas high-level talent million venture capital funds in Qingdao, Dr. Zhuang Dejin has been developing nitride semiconductor substrate wafers in Qingdao for three years. Nowadays, the first batch of crystals developed by Zhuang Dejin team has been introduced to the market, which is expected to replace the existing sapphire substrates in the field of LED lighting, change the LED industry chain, and accelerate the popularization of LED lighting to ordinary households.
“The growth of this substrate wafer developed by our team is twice as large as that of the US company. The performance is even better and the cost is reduced by half.†On the afternoon of the 15th, at Qingdao Aluminum Gallium Opto Semiconductors Co., Ltd. in Laoshan District, Zhuang Dejin introduced the nitride semiconductor substrate wafers they developed. Nitride wafer is the source of LED optoelectronic semiconductor industry chain. It is the substrate material for LED epitaxial wafer preparation. The device made on the basis of this semiconductor substrate wafer can be applied to high temperature and high frequency, automobile engine, drilling bit and so on. In the high-temperature field, LED lighting products will be more than doubled in luminous efficiency compared to current aluminum oxide substrates.
According to reports, GaN substrate wafers have the advantages of low cost and high cost performance, which can drive the downstream industry to adjust the technical structure and improve production efficiency. “For example, in the past, a total of 15 steps were required to produce an LED product. After using a GaN substrate wafer, the production process only took six or seven steps.†Zhuang Dejin said that after the GaN substrate wafer was introduced to the market, It is expected to replace the existing sapphire and other substrate materials in the high-end field, and truly change the LED industrial chain, and will promote the popularity of LED lighting to ordinary households to a certain extent, and further achieve the effect of energy saving and environmental protection.
“The main difficulty in the development of this project is funding. The government has given me a lot of help in this regard.†Zhuang Dejin said that he came to Qingdao in 2009 and became the first batch of overseas high-level talent innovation and entrepreneurship start-up fund winners in Qingdao. 1 million yuan project start-up gold. Subsequently, Zhuang Dejin also obtained a total of more than 7 million yuan from the Ministry of Science and Technology, Qingdao Science and Technology Bureau, Laoshan District, and other shareholders, and Qingdao also provided various living guarantees for Zhuang Dejin and his family and children.
Today, the Zhuang Dejin team has cooperated with several well-known domestic enterprises and research institutes such as the Institute of Physics of the Chinese Academy of Sciences. "The production capacity is limited now, and many large orders are not dare to pick up." Zhuang Dejin said that the GaN substrate wafer was just introduced to the market last year. As the market demand continues to expand, Zhuang Dejin will lead his project team to Qingdao. The Wanping Rice Incubator will further expand the production scale, and the existing production capacity will be greatly improved by then.
Tier 1 Solar Panel
Chinese Tier 1 brand Solar Panel (Longi, Jinko, Trina, Canadian, Ja etc.)
This type of product is mainly Tier 1 solar module product in China, include Longi solar panel. Jinko solar panel, Canadian Solar panel, ja solar panel etc.all of which are among the top 10 world-renowned brands. The original A grade product is mainly mono crystalline and half cut cell solar modules, with a power range of 400watts to a maximum of 700watts.quality warranty is 25 years.
A grade, this type of film is characterized by a neat and uniform appearance, printed electrode grid lines, no broken grid, no surface stains, no leakage, no aluminum package, no hidden cracks, no scratches, no black core, no reverse current, stable electrical performance, and high conversion efficiency
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.
