北京、内蒙古和东北地区的未来——太阳能、风能、水能的互补

本文较系统地介绍了当代＂第三代＂光伏发电技术的发展,指出这一技术将取代现在正在迅速发展的＂第一代＂晶体硅和＂第二代＂薄膜光伏发电技术。在国外发展的＂第三代＂是＂400倍、1000倍、2000倍聚光＋高精度跟踪＋高转化率、耐高温砷化镓聚光电池＂的技术路线。在中国发展的是＂太阳能炼硅＋低倍聚光＋跟踪＋高效硅基聚光电池＂的技术路线,其成本电价已下降到0.7元/千瓦时。

Future for Beijing,Inner Mongolia,and northeastern region of China——A combined application of solar,wind and water energies

The contemporary "Third-generation" technology—photovoltaic technology—is generally introduced to generate electricity,and it is pointed out that this technology will replace the "First-generation" and "Second-generation" photovoltaic technologies.There exist different ways for the development of the "Third-generation" photovoltaic technology in foreign countries and China.In China,this technology makes it possible for the cost of electricity to be decreased to RMB 0.7 per kilowatt-hour.A new aquatic photovoltaic technology "Solar Lotus" is also introduced to generate electricity.
