Three characteristics of flexible thin film solar cells:
"Can be curled", can be easily installed on the outside of an irregular roof or vehicle; "Light weight", stainless steel substrate thickness is only 0.127 mm, very thin; "Low installation cost", Xenon Solar Energy is both a photovoltaic cell production Businesses are also designers and manufacturers of production equipment, so the cost of electricity generation is low.
In the breeze of the day, people rested on the lawn. Someone took out a piece of solar battery that was curled or folded like a piece of paper from a backpack, spread out and connected to laptops, mobile phones, and digital cameras. This is not science fiction, but reality.
However, for Dr. Deng Xunming, who is the CEO of Solar Energy, the company that allows solar energy to be "rolled up" and taken away, the most important thing at present is not to miniaturize solar battery chargers, but to further improve solar cells. Conversion efficiency, increase production capacity. “The production of flexible thin-film solar cells is divided into three steps: the production of thin-film battery roll-to-roll, the assembly of solar cells, and the packaging of photovoltaic modules. The first step we have made is the assembly of flexible cell sheets and the encapsulation of photovoltaic modules in Xunli Kunshan, and we are now doing The EIA will strive to introduce Xerox’s US front-end film roll-to-roll production equipment and manufacturing process to China as soon as possible.â€
In December 2009, New York’s Times Square, Xenon Solar was able to use its own flexible thin film solar cell to complete a project to power the Japanese Ricoh billboard. This is the first 100% solar-powered billboard in Times Square. Weekly magazine, The Wall Street Journal and others have made special reports.
Dr. Deng Xunming is currently a tenured professor at the University of Toledo, USA. In 1985, he passed the Sino-U.S. Joint Recruitment Examination of the United States and went to the US Graduate Physics Program in Japan to study physics at the University of Chicago. Today, he is the holder of many world records for amorphous silicon solar cells. In 2002, Dr. Deng Xunming and Dr. Xu Liwei founded China and Western Optoelectronics in the United States. In 2006, a subsidiary company, Xunli Solar, was established to specialize in the industrialization of flexible thin film solar cells.
After the establishment of the US Xunli Solar Energy Company, Deng Xunming completed the world's first 0.91m (three ft) wide and two megawatt amorphous silicon thin film battery pilot production line in 2008. Immediately afterwards, the new round of venture capital investment entered. In 2009, Xunli Solar completed a 25 MW commercialized production line and achieved a major technological breakthrough. This production line with completely independent intellectual property rights is “just like printing presses and newspapersâ€. It is possible to coat three stacks of thin-film silicon solar cells on a 0.91-meter-wide and 1.6-km-long stainless steel roll at a time, in terms of width, power generation, etc. It has created many "world firsts".
Deng Xunming said that the current conversion efficiency of Xunli solar energy solar cells is stable at around 8%, and ranks first with U.S. joint solar energy companies. Although flexible thin-film solar cells have a certain distance from 14%-18% conversion efficiency of crystalline silicon cells, the prospects are bright.
This is because the most important feature of flexible thin-film solar cells is "can be curled" and can be easily installed on irregular roofs or vehicles; the second major feature is "light weight", and general solar cell installation requires metal frames. Or to strengthen the roof, flexible thin-film solar cell stainless steel substrate thickness of only 0.127 mm, very thin; the third largest feature "low installation costs," Xenix Solar is both a photovoltaic cell manufacturer, but also the production equipment designer and manufacturing Because of this, the cost of electricity generation is low, and "comprehensive considerations, flexible batteries are the best."
