In 1958, China successfully developed its first silicon single crystal. This breakthrough marked an important step towards the future of solar technology. Fast forward to 1968-1969, a semiconductor company took on the challenge of creating silicon solar panels for the "Practice No. 1 Satellite." During these studies, researchers discovered that P+/N monolithic solar cells suffer from electron radiation while operating in space, leading to battery degradation and limiting their operational lifespan. As a result, the semiconductor institute halted further research on silicon solar cells.
In 1969, Tianjin 18 stepped up to develop solar cell arrays for geosynchronous orbit satellites like the Dongfanghong 2, 3, and 4 series. Progress continued in 1975 when Ningbo and Kaifeng established solar cell factories. These facilities initially replicated the methods used for producing space batteries, marking the beginning of solar cell applications reaching Earth-bound projects.
The year 1998 was pivotal as the Chinese government initiated interest in solar power generation. They proposed building the nation’s first 3MW polysilicon battery and application system demonstration project. This initiative caught the attention of Miao Liansheng, then Chairman of Tianwei Yingli New Energy Co., Ltd., who saw immense potential in this emerging field. Despite the uncertainty surrounding the solar industry at the time and discouragement from some due to policy constraints, Miao pressed ahead and secured approval for the project, becoming a pioneer in China’s solar sector.
By 2001, Wuxi Suntech had established a 10MWp (megawatt) solar cell production line. Just a year later, in September 2002, Suntech launched its first solar cell production line, boasting a capacity equivalent to the total national production of solar cells over the previous four years. This achievement dramatically narrowed the gap between China and global leaders in the photovoltaic industry by about 15 years.
From 2003 to 2005, spurred by European demand—especially from Germany—both Suntech and Baoding Yingli expanded their production capacities. Numerous other companies also entered the fray, establishing solar cell production lines, which fueled rapid growth in China's solar cell manufacturing sector.
In 2004, China Silicon High-tech Co., Ltd., formed through collaboration between Luoyang Monocrystalline Silicon Factory and China Nonferrous Metals Design Institute, independently developed 12 energy-efficient polysilicon reduction furnaces. Building on this innovation, they completed and launched the nation’s first 300-ton polysilicon production facility in 2005, setting the stage for China’s polysilicon development journey.
By 2007, China had become the world leader in solar cell production, with output jumping from 400MW in 2006 to 1088MW. In 2008, production surged to 2600MW, and by 2009 it reached 4000MW. Globally, solar cell output increased from 2500MW in 2006 to 10700MW in 2009.
These advancements reflect China’s growing dominance in the renewable energy landscape. Today, China continues to push boundaries, investing heavily in renewable technologies to address environmental challenges and meet rising energy demands. While the path hasn’t always been smooth, each milestone achieved underscores the resilience and determination of those who dared to innovate. As we look to the future, the story of China’s solar industry serves as both inspiration and cautionary tale, reminding us that progress often requires boldness and perseverance.
