什么是光伏发电?光伏发电的工作原理光伏发电是利用半导体界面的光生伏特效应而将光能直接转变为电能的一种技术。这种技术的关键元件是太阳能电池。太阳能电池经过串联后进行封装保护可形成大面积的太阳电池组件，再配合上功率控制器等部件就形成了光伏发电装置。光伏发电的优点是较少受地域限制，因为阳光普照大地;光伏系统还具有安全可靠、无噪声、低污染、无需消耗燃料和架设输电线路即可就地发电供电及建设同期短的优点。

　　What is photovoltaic power generation? The working principle of photovoltaic power generation is a technology that utilizes the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. The key component of this technology is solar cells. After being connected in series and packaged for protection, solar cells can form large-area solar cell modules, which are combined with power controllers and other components to form photovoltaic power generation devices. The advantage of photovoltaic power generation is that it is less restricted by geographical conditions, as sunlight shines on the earth; Photovoltaic systems also have the advantages of safety, reliability, no noise, low pollution, no need to consume fuel, on-site power generation and short construction period without installing transmission lines.

　　光伏发电是根据光生伏特效应原理,利用太阳能电池将太阳光能直接转化为电能。不论是独立使用还是并网发电,光伏发电系统主要由太阳能电池板(组件)、控制器和逆变器三大部分组成，它们主要由电子元器件构成，不涉及机械部件,所以,光伏发电设备极为精炼,可靠稳定寿命长、安装维护简便。理论上讲,光伏发电技术可以用于任何需要电源的场合,上至航天器,下至家用电源,大到兆瓦级电站,小到玩具,光伏电源无处不在。太阳能光伏发电的最基本元件是太阳能电池(片)，有单晶硅、多晶硅、非晶硅和薄膜电池等。目前，单晶和多晶电池用量最大，非晶电池用于一些小系统和计算器辅助电源等。

　　Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert solar energy into electricity. Whether used independently or connected to the grid for power generation, photovoltaic power generation systems mainly consist of three parts: solar panels (components), controllers, and inverters. They are mainly composed of electronic components and do not involve mechanical components. Therefore, photovoltaic power generation equipment is extremely refined, reliable, stable, with a long lifespan and easy installation and maintenance. In theory, photovoltaic power generation technology can be used in any situation that requires power, from spacecraft to household power sources, from megawatt level power plants to toys, photovoltaic power is everywhere. The most basic component of solar photovoltaic power generation is solar cells, including monocrystalline silicon, polycrystalline silicon, amorphous silicon, and thin-film cells. At present, single crystal and polycrystalline batteries have the largest usage, while amorphous batteries are used for some small systems and auxiliary power supplies for calculators.

　　国产晶体硅电池效率在10至13%左右，国外同类产品效率约12至14%。由一个或多个太阳能电池片组成的太阳能电池板称为光伏组件。目前，光伏发电产品主要用于三大方面:一是为无电场合提供电源，主要为广大无电地区居民生活生产提供电力，还有微波中继电源、通讯电源等，另外，还包括一些移动电源和备用电源;二是太阳能日用电子产品，如各类太阳能充电器、太阳能路灯和太阳能草坪灯等;三是并网发电，这在发达国家已经大面积推广实施。我国并网发电还未起步，不过，2008年北京奥运会部分用电将会由太阳能发电和风力发电提供。

　　The efficiency of domestically produced crystalline silicon batteries is around 10% to 13%, while the efficiency of similar foreign products is about 12% to 14%. A solar panel composed of one or more solar cells is called a photovoltaic module. At present, photovoltaic power generation products are mainly used in three aspects: firstly, to provide power for non electric fields, mainly for the daily life and production of residents in non electric areas, as well as microwave relay power, communication power, etc. In addition, it also includes some mobile power sources and backup power sources; The second is solar powered daily electronic products, such as various solar chargers, solar street lights, and solar lawn lights; The third is grid connected power generation, which has been widely promoted and implemented in developed countries. China's grid connected power generation has not yet started, but some of the electricity used for the 2008 Beijing Olympics will be provided by solar and wind power.
