Germany MANZ Group CIGS thin film solar cell conversion rate of 21.7%
On the morning of October 16, MANZ Group, a German manufacturer of high-tech equipment, announced in Beijing that the company's laboratory conversion rate for CIGS thin-film solar cells rose from 21% to 21.7%, setting a new world record. According to the China New Energy Channel, CIGS (copper & indium gallium selenide) thin film solar technology is a quaternary compound semiconductor thin film battery composed of four elements of copper, indium, gallium, and selenium, which is currently the world's most potential In addition, solar energy technology with improved performance and reduced cost can be realized in one step. At present, the technology is mainly applied abroad. According to Dr. Claus Kuhn, Manz's global vice president of thin-film solar energy, the difference between the conversion efficiency of CIGS thin films and the conversion efficiency of polycrystalline silicon cells will expand to 1.3% (recorded as 20.4% in crystalline silicon) after “21.7%†hits the world record. The cost will also drop substantially. He expects that CIGS thin-film solar modules will become an important part of the next wave of solar power investment. As we all know, the cost issue has always been a major problem that has plagued the development of China's photovoltaic industry, and the quality problems caused by the inability to break through technology and product price war are even more alarming. According to Lin Junsheng, Manz's deputy general manager of Asia, the production cost of CIGS thin-film batteries can be reduced by 50% compared with the current polycrystalline silicon solar cells that are more prevalent. The chief scientist of the National Major Scientific Research Program, Director of the Photovoltaic Solar Center Laboratory of the Institute of Advanced Technology of the Shenzhen Institute of Advanced Technology, and Professor Xiao Xudong of the Physics Department of the Chinese University of Hong Kong stated that reducing the cost is a continuing goal of the current solar power industry. The continuous improvement of efficiency and continuous reduction in costs will increase the competitiveness of solar power. According to him, the cost of CIGS thin-film solar power generation can be equivalent to thermal power, or lower than 0.3 yuan per kWh. Power generation efficiency is 10%-20% higher than that of ordinary crystalline silicon cells. In addition, energy consumption is also relatively low. "Crystalline silicon cell energy recovery cycle is 2.7 years, cadmium telluride battery is 1 year, amorphous silicon battery is 1.3 years, and only copper indium gallium selenide battery is less than 1 year. This time the new "21.7%" new world record Based on the inherent advantages of CIGS, it has made up for the short-circuit of thin-film batteries, added Xiaoxu Dong. Xiao Xudong also said: "The only problem with this technology is indium because it is a rare metal. However, we are not overly pessimistic. The data show that in 2006, China's proved reserves were 1300 tons, and by 2008 it has increased. At 8,000 tons, there are still a lot of indium in the earth's crust, which is just waiting for us to explore it further." Pollen screens have become an essential tool for individuals who suffer from allergies or sensitivities to pollen. These screens are specifically designed to filter out pollen particles, providing relief and creating a more comfortable indoor environment. Made from a fine mesh material, pollen screens effectively trap and prevent pollen from entering through windows and doors, reducing the allergen levels inside. By blocking pollen, these screens help alleviate symptoms such as sneezing, itching, and congestion. With their easy installation and low maintenance requirements, pollen screens offer a practical and effective solution for creating a pollen-free sanctuary within your home, allowing you to enjoy the beauty of nature without the discomfort of allergies.
