光伏发电系统储能蓄电池太阳电池组件及方阵 1.太阳电池的基本原理和光伏发电的主要优势 The main advantage of basic principle and photovoltaic power generation 1 solar cells. 1.1 太阳电池的基本原理 The basic principle of the 1.1 solar cells 太阳能光伏发电是太阳能利用的一种重要形式，是采用太阳电池 将光能转换为电能的发电方式，而且随着技术不断进步，光伏发电有 可能成为最具发展前景的发电技术之一。太阳电池的基本原理为半导 体的光伏效应。当太阳光(或其它光)照射到太阳电池上时，电池吸 收光能，产生“光生电子—空穴”对。在电池内电场作用下，光生电 子和空穴被分离，从而在电池两端积累起异号电荷，即产生电压。 Solar photovoltaic power generation is an important form of solar energy utilization, is the use of solar energy is converted into electricity energy, and as the technology continues to progress, photovoltaic power generation has the potential to become one of the most promising power generation technology. The basic principle of solar cell photovoltaic effect of semiconductors. When the sun light ( or other light ) exposure to solar cells, batteries absorb light energy, produce photogenerated electron-hole on. The action of the electric field inside the battery, the photogenerated electrons and holes are separated, resulting in the two ends of the cell to accumulate the heterocharge, generates a voltage. 光伏发电系统储能蓄电池太阳电池组件及方阵 1.2 光伏发电的主要优势 The main advantage of 1.2 photovoltaic power generation (1)发电原理具有先进性:即直接从光子转换到电子，没有中 间过程(如热能—机械能、机械能—电磁能转换等)和机械运动，发 电形式极为简捷。 ( 1 ) the generation principle is advanced: directly from the photon conversion to electronic, no intermediate process ( such as heat energy, mechanical energy, mechanical energy and electromagnetic energy conversion) and mechanical motion, power generation is very simple.
