industrial revolution, the rapid development of the industry have brought great convenience to human life, but at the same time the need of energy is getting more. It will let us face with a serious energy crisis. In fact, the use of oil and coal caused global climate get worse. So the new energy exploration and research has bee a topic of mon concern of all countries in the world. In many kinds of new energy, solar energy is the most primitive and inexhaustible. It is a kind of renewable energy, but also the primary energy. Solar energy is ing to the earth mainly as light and heat. Solar energy does not pollute the environment, does not need to transport, carry by light. So in a number
