1981年3月我应邀去中国,有机会参观访问了中国正在从事研究太阳能的几个城市,即兰州、上海、广州、北京等地的一些研究所和大学,同时与中国的一些高级研究人员和工程技术人员进行了技术座谈。此次去中国的主要目的是给中国从事太阳能项目的技术人员提供一些有关的技术情报,故每到之处均举行了学术报告会。中国尽管拥有大量的煤炭,出口一些石油,亦有丰富的水力发电资源。但这个拥有十亿人口的国家,许多人民至今仍还得不到能源的供应。因此中国政府通过大约在十多个研究所和大学的数百名技术专家来支持太阳能研究工作的发展。中国的太阳能研究和发展程度不同,既有很高的技术研究,又有实际的各种应用和发展项目。第一个方面是光电池的改进。起初是单晶硅电池、选择性途层在玻璃和各
In March 1981, I was invited to visit China and had the opportunity to visit some of the cities where China is researching solar energy, namely, Lanzhou, Shanghai, Guangzhou and Beijing, as well as with some senior researchers in China and Engineering and technical personnel conducted a technical discussion. The main purpose of this trip to China is to provide some technical intelligence to China's technicians engaged in solar projects so that academic presentations are held everywhere. Although China owns a large amount of coal, it exports some oil and also has abundant hydropower resources. However, many people in this country with a billion people still have no access to energy. Therefore, the Chinese government supports the development of solar energy research through hundreds of technical experts in about 10 research institutes and universities. China's solar energy research and development to varying degrees, both high technology research, but also a variety of practical applications and development projects. The first area is the improvement of photovoltaic cells. At first it was monocrystalline silicon cells, selectively routed in glass and each
