说明：  虽然不是自己写的，但是有非常高的参考价值。通过对光伏系统的基本组成，基本原理等的研究，其中重点对太阳能电池的特性，蓄电池的特性，及光伏系统的配置分别进行了讨论，就未来世界能源发展问题进行了分析
(Although it is not written by myself, it has a very high reference value. Through the basic composition of photovoltaic system,Research on the basic principles, especially the characteristics of solar cell, battery and photovoltaic systemThe configuration is discussed separately, and the future energy development in the world is analyzed)
