Dazheng won the first place in the growth group of the Advanced Manufacturing Global Finals of the sixth Tsinghua Alumni Three Innovation Competition
On the afternoon of September 25, the 6th Tsinghua Alumni Tri-Competition Advanced Manufacturing Global Grand Final, co-hosted by Tsinghua Alumni Association and Luoyang Municipal People's Government, and hosted by the Municipal Science and Technology Bureau, Municipal Science and Technology Association, High-tech Zone Management Committee, Tsinghua Alumni Association Advanced Manufacturing Special Committee and Qingluo Base, was grandly opened in Luoyang. The finals focused on advanced manufacturing-related fields, and 104 high-quality projects from eight domestic regions, including Tsinghua Park, Beijing-Tianjin Wing, Yangtze River Delta, Guangdong, Hong Kong and Macau, and European international regions, came together in Luoyang to compete!
It is reported that this finals, gathered more than a hundred high-quality projects, gathered a number of industry elites.
Our general manager Yu Wang participated in the competition with the project "Flexible Calcium Titanite Solar Cells", and finally won the top ten awards in the growth group with the first place in the overall score of the growth group!
The following is the top ten list of the growth group
Ltd. is a leading, national high-tech enterprise in the manufacture of new calcium titanite thin film solar cell modules and related precision equipment. In January this year, it reported the world's highest efficiency of 21.1% for flexible chalcogenide solar cells.
In the future, Dazheng Micro-Nano will take one step at a time and try its best to bring clean and efficient new energy to mankind, and contribute its share of strength to the strong country of science and technology.
A perovskite solar cell (PSC) is a type of solar cell which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture. Perovskites have inherent properties such as broad absorption spectrum, fast charge separation, long electron and hole transport distance, and long carrier separation lifetime, making them very promising solid-state solar cell materials.
A perovskite is any material with a crystal structure following the formula ABX3, which was first discovered as the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3). Perovskites have a nearly cubic structure and the chemical formula is ABO3. Typically perovskite compounds have the chemical formula ABX3, where "A" and "B" represent cations and X is an anion bound to both. A large number of different elements can combine to form a perovskite structure. Using this compositional flexibility, scientists can design perovskite crystals with a variety of physical, optical, and electrical properties. Today, perovskite crystals are found in ultrasonic machines, memory chips and current solar cells.
Tandem solar cells are an important strategy to push the Shockley-Queisser (S-Q) efficiency limit of single-junction solar cells, it can be lower the cost per watt.
