"The battery conversion efficiency and single chip processing cost of this project have reached the industry-leading level, and the annual output value after full production can reach 30 billion yuan, providing 8000 jobs. The annual output of batteries put into our project is equivalent to half of the annual output of the Three Gorges Hydropower Station." Cao Yunbo, the head of Xixian New Area Base of Longji Green Energy Technology Co., Ltd., said. In the golden autumn, the reporter came to the world's largest single photovoltaic cell production and research and development base on the Loess Plateau and walked into the Qinchuangyuan Photovoltaic Innovation Center - Longji Central Research Institute in the park. A pilot line of more than 200 meters long came into sight, and the equipment made a low noise. The researchers gathered to check the display screen parameters while discussing. The crystalline silicon solar cell, which has completed the technical breakthrough and is about to go into mass production, will be completed in the last 100 meters from research and development to production here. "Every 0.01 percentage point increase in battery conversion efficiency is significant." Xu Xixiang, vice president of Longji Central Research Institute, said that since April 2021, Longji Green Energy has broken the world record for battery conversion efficiency 11 times. In his succinctly furnished office, the reporter saw the photovoltaic cell in the picture frame at a glance. This is a souvenir made by Longji's R&D team last October after raising the conversion efficiency of a battery to 26.30% and breaking the world record. Now, this value has been raised to 26.50% by them. "When we first returned to China in 2010, more than 90% of the R&D and manufacturing equipment in the domestic photovoltaic industry depended on imports. With the efforts of the whole industry, China has achieved self control in this field." Xu Xixiang told reporters. Bearing in mind the ardent instructions of the General Secretary, Shaanxi has made every effort to promote the close integration of science and technology with the economy, the close connection between innovation achievements and industrial development, and make more scientific research achievements directly face the main economic battlefield. "This plasticine like thing will be 'strong when it is strong' after being impacted by external forces." Pointing to a new type of material, Zhang Yanfeng, the person in charge of Shaanxi Toruikao New Material Technology Co., Ltd. and the vice president of Xi'an Jiaotong University School of Chemistry, told the reporter that this nano intelligent energy absorbing material project, based on the scientific research achievements of Xi'an Jiaotong University, was incubated into an enterprise in only 42 days last year with the support of Qin Chuangyuan Spring Seed Fund, and realized the commercialization of achievements within 4 months. Now, this material has been applied to the manufacturing of sports equipment, motorcycle riding clothes, etc. "The name of the company is borrowed from the English language of the Terracotta Warriors to show the Shaanxi people's determination to forge ahead and seize the day." Zhang Yanfeng introduced that the development process of Tuoruikao is the epitome of Shaanxi's efforts to ensure the input of factors and service, and to explore and cultivate a number of science and technology manufacturing enterprises with strong innovation and high growth. "More and more college teachers around me actively participate in the deep integration of innovation chain and industrial chain, contributing to the transformation and upgrading of the country's industry." He said. Firmly establish the concept of "green water and green mountains are golden mountains and silver mountains", and Shaanxi will continue to do a good job in ecological environment protection.
