一.背景：
能源是現代社會存在和發展的基石。隨著全球經濟社會的不斷發展，能源消費也相應的持續增長。隨著時間的推移，化石能源的稀少性越來越明顯。太陽能是人類取之不盡用之不竭的可再生能源，具有充分的清潔性、安全性、相對的廣泛性、確實的長壽命和免維護性、資源的充足性及潛在的經濟性等優點，在長期的能源戰略中具有重要地位。
太陽能是一種可持續利用的清潔能源，當前世界面臨人口、資源、環境的挑戰，在尋求人類社會可持續發展的進程中，太陽能利用日益為世界各國所重視，太陽能作為一種合理、沒有污染的可再生資源，目前已逐漸被各行各業所利用。這對減緩人類能源緊張狀況，減少環境污染，同時提高人們的生活水平，具有非常重要的意義。
一、 Background
Energy is the cornerstone of the existence and development of modern society. With the continuous development of global economy and society, energy consumption is also growing correspondingly. As time goes on, the scarcity of fossil energy becomes more and more obvious. Solar energy is an inexhaustible renewable energy for human beings. It has the advantages of full cleanliness, absolute safety, relative universality, long life and maintenance free, sufficient resources and potential economy, and plays an important role in the long-term energy strategy.
As we all know, solar energy is a kind of sustainable clean energy. At present, the world is facing the challenges of population, resources and environment. In the process of seeking the sustainable development of human society, the use of solar energy is increasingly valued by all countries in the world. As an efficient and pollution-free renewable resource, solar energy has been gradually used by all walks of life. It is of great significance to alleviate the shortage of human energy, reduce environmental pollution and improve people's living standards
