Raw material glass tube, whose collector component is all glass vacuum solar collector, was first introduced in the 1970s. Based on the gradual film invented by Sydney University in Australia in 1977, it was developed by Oscar Company of the United States. It has good heat collection and thermal insulation characteristics at a certain temperature. In the early 1980s, Mr. Bellukun, an American Chinese, introduced it into China, and after painstaking research by engineers of Shenyang Glass Design Factory, the vacuum tube came out in China. In 1984, Professor Yin Zhiqiang of Tsinghua University invented the technology of gradient "Al N/Al" selective absorption coating, which has been produced on a large scale by many domestic companies. Its excellent performance laid the foundation for the great development of China's solar thermal utilization industry and initiated the industrialization of all-glass vacuum solar collector tubes in China.
