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，那你知道光伏发电的主要原理是什么效应内容吗？

Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interface to directly convert light energy into electrical energy. Do you know what the main principle of photovoltaic power generation is?

实际上光伏发电主要由太阳能电池板（组件）、控制器和逆变器三大部分组成，主要部件由电子元器件构成。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能电池组件，再配合上功率控制器等部件就形成了光伏发电装置。

In fact, photovoltaic power generation is mainly composed of solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After the solar cells are connected in series, they can be packaged and protected to form a large area of solar cell modules, which together with power controller and other components form a photovoltaic power generation device.

光伏发电的主要原理是半导体的光电效应。光子照射到金属上时，它的能量可以被金属中某个电子全部吸收，电子吸收的能量足够大，能克服金属内部引力做功，离开金属表面逃逸出来，成为光电子。硅原子有4个外层电子，如果在纯硅中掺入有5个外层电子的原子如磷原子，就成为N型半导体。

The main principle of photovoltaic power generation is the photoelectric effect of semiconductor. When a photon shines on a metal, its energy can be fully absorbed by an electron in the metal. The energy absorbed by the electron is large enough to overcome the internal gravity of the metal to do work, escape from the metal surface and become a photoelectron. Silicon atom has four outer electrons. If pure silicon is doped with atoms with five outer electrons, such as phosphorus atoms, it becomes an N-type semiconductor.

若在纯硅中掺入有3个外层电子的原子如硼原子，形成P型半导体。当P型和N型结合在一起时，接触面就会形成电势差，成为太阳能电池。当太阳光照射到P-N结后，电流便从P型一边流向N型一边，形成电流。

If pure silicon is doped with atoms with three outer electrons, such as boron atoms, a P-type semiconductor is formed. When P type and N type are combined, the contact surface will form a potential difference and become a solar cell. When the sunlight shines on the P-N junction, the current flows from the P side to the N side, forming a current.

光伏发电过程简单，没有机械转动部件，不消耗燃料，不排放包括温室气体在内的任何物质，无噪声、无污染。太阳能资源分布广泛且取之不尽、用之不竭。

The photovoltaic power generation process is simple, without mechanical rotating parts, no fuel consumption, no emission of any substance including greenhouse gases, no noise, no pollution. Solar energy resources are widely distributed and inexhaustible.

因此，与风力发电、生物质能发电和核电等新型发电技术相比，光伏发电是一种具可持续发展理想特征的可再生能源发电技术 。您有什么需求随时来我们网站//tianjibiotech.com进行咨询吧！
