太阳电池是一种直接将太阳辐射能转换成电能的半导体器件。自六十年代开始,太阳电池首先在空间科学上得到应用。美国于1973年5月14日发射的“天空实验室”,安装了至今为止世界上空间应用最大的硅太阳电池方阵,总输出功率达21千瓦。在空间应用的基础上,太阳电池在地面的应用也获得了广泛的发展,逐步成为一种特殊场合下的辅助能源。作为小功率的特殊电源,太阳电池已在灯塔、航标灯、微波中继站、电围栏、铁路信号灯、无线电话机、电视差转机、电视
Solar cells are semiconductor devices that directly convert solar radiation energy into electrical energy. Since the 1960s, solar cells have first been applied in space science. The “Sky Lab” launched by the United States on May 14, 1973, installed the largest array of silicon solar cells in the world for space applications to date, with a total output of 21 kilowatts. On the basis of space applications, the application of solar cells on the ground has also been extensively developed, gradually becoming an auxiliary energy source for special occasions. As a special low-power power supply, solar cells have been in the lighthouse, beacon lights, microwave relay stations, electric fences, railway lights, radiotelephones, TV differentials, televisions
