Shi Zhengrong, chairman and CEO of Wuxi Suntech Power Co., Ltd., told Netease Finance that with the help of nanotechnology, the conversion rate of silicon materials will reach 35% in the future, which will become a “revolutionary breakthrough†in solar power technology. Netease Finance Recently, as a special media, I conducted a survey at the Suntech headquarters in Wuxi.
The mainstream material of solar photovoltaic cells is silicon, so the conversion rate of silicon materials has always been an important factor restricting the further development of the entire industry. Shi Zhengrong said that the classical theoretical limit of silicon material conversion rate is 29%. His team created a record of 25% in the laboratory. Suntech's silicon conversion rate technology breakthrough Pluto plan is based on this data, is investing this technology. industry. At present, the conversion rate of Suntech's large-scale commercial production of photovoltaic solar panels is about 19%.
Shi Zhengrong also said that their laboratory can now extract high-purity silicon directly from silica without converting it into metal silicon, and then extracting silicon from it. This can reduce intermediate links and improve efficiency.
He revealed that combining the third-generation nanotechnology with existing technologies can increase the conversion rate of silicon materials to more than 35%. If large-scale commercial mass production is put into use, the cost of solar power generation will be greatly reduced. The good news is that such technology "has been completed in the laboratory and is awaiting the process of industrialization."
Wuxi Suntech Power is currently ranked third in the global solar photovoltaic cell market and has several world-leading patents for power generation technology. Suntech Power was successfully listed on the New York Stock Exchange in December 2005. The market value once exceeded 10 billion US dollars. Shi Zhengrong was also named the richest man in China by Forbes in 2006. In 2008, Suntech Power achieved 500 MW of products and its tax sales revenue exceeded US$1.9 billion.
