What is the working principle of the plasma etcher in the solar cell制作太阳能电池中的等离子刻蚀机的工作原理是怎么样的

太阳能电池发电原理: 

太阳能电池是一对光有响应并能将光能转换成电力的器件。能产生光伏效应的材料有许多种,如:单晶硅,多晶硅,非晶硅,砷化镓,硒铟铜等。它们的发电原理基本相同,现以晶体为例描述光发电过程。P型晶体硅经过掺杂磷可得N型硅,形成P-N结。 

当光线照射太阳能电池表面时,一部分光子被硅材料吸收;光子的能量传递给了硅原子,使电子发生了越迁,成为自由电子在P-N结两侧集聚形成了电位差,当外部接通电路时,在该电压的作用下,将会有电流流过外部电路产生一定的输出功率。这个过程的实质是:光子能量转换成电能的过程。 

晶体硅太阳能电池的制作过程: 

“硅”是我们这个星球上储藏最丰量的材料之一。自从19世纪科学家们发现了晶体硅的半导体特性后,它几乎改变了一切,甚至人类的思维。20世纪末,我们的生活中处处可见“硅”的身影和作用,晶体硅太阳能电池是近15年来形成产业化最快的。生产过程大致可分为五个步骤:a、提纯过程 b、拉棒过程 c、切片过程 d、制电池过程 e、封装过程。

太阳能电池的应用: 

上世纪60年代,科学家们就已经将太阳电池应用于空间技术——通信卫星供电,上世纪末,在人类不断自我反省的过程中,对于光伏发电这种如此清洁和直接的能源形式已愈加亲切,不仅在空间应用,在众多领域中也大显身手。如:太阳能庭院灯、太阳能发电户用系统、村寨供电的独立系统、光伏水泵(饮水或灌溉)、通信电源、石油输油管道阴极保护、光缆通信泵站电源、海水淡化系统、城镇中路标、高速公路路标等。欧美等先进国家将光伏发电并入城市用电系统及边远地区自然界村落供电系统纳入发展方向。太阳电池与建筑系统的结合已经形成产业化趋势 生产不稳定是非晶硅生产中的最大难点.

     Principle of solar cell power generation: 

     Solar cell is a device that responds to light and can convert light energy into electricity. There are many kinds of materials that can produce photovoltaic effect, such as monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium indium copper, etc. The principle of their power generation is basically the same. Now we take crystal as an example to describe the process of optical power generation. P-n junction is formed by doping p into p-type crystalline silicon. 

    When the light hits the solar cell surface, some photons are absorbed by the silicon material; the energy of photons is transferred to the silicon atom, which makes the electrons move over and become the free electrons gathering on both sides of the p-n junction to form the potential difference. When the external circuit is connected, under the action of this voltage, there will be a current flowing through the external circuit to generate a certain output power. The essence of this process is the conversion of photon energy into electrical energy. 

    The process of making crystalline silicon solar cells: "Silicon" is one of the most abundant materials on our planet. Since scientists discovered the semiconductor properties of crystalline silicon in the 19th century, it has changed almost everything, even human thinking. At the end of the 20th century, we can see the figure and function of "Silicon" everywhere in our life. Crystalline silicon solar cells are the fastest to form industrialization in the past 15 years. The production process can b e roughly divided into five steps: A, purification process B, rod pulling process C, slicing process D, battery making process e, packaging process. 

   Application of solar cells: 

   In the 1960s, scientists have applied solar cells to space technology -- communication satellite power supply. At the end of the last century, in the process of human self reflection, photovoltaic power generation, such a clean and direct energy form, has become more and more intimate, not only in space applications, but also in many fields. Such as: solar courtyard lamp, solar power generation system, independent system of village power supply, photovoltaic water pump (drinking water or irrigation), communication power supply, cathodic protection of oil pipeline, power supply of optical cable communication pump station, desalination system, urban middle road sign, highway road sign, etc. Advanced countries such as Europe and the United States will integrate photovoltaic power generation into urban power system and natural village power supply system in remote areas into the development direction. The combination of solar cells and building systems has formed a trend of industrialization. Unstable production is the biggest difficulty in the production of amorphous silicon. 

   Founded in 2014, Suzhou saisen Electronic Technology Co., Ltd. is a company that provides remanufacturing equipment, spare parts and services for domestic semiconductor, MEMS and photoelectric industry customers. Our core product lines include Novellus C1 / C2 PECVD, Lam Rainbow / TCP series etchers and Amat p5000 / Centura platform CVD / etchers.
