英 文 翻 译系 别 自动化系 专 业 自动化 班 级 163002 学生姓名 白 冰 学 号 103588 指导教师 王卫军 英文资料及译文THE SOLAR PANELS Solar panels is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the silicon, but because of the production cost is very big, so that it cant be extensive and widespread use. Solar energy: the sun is a huge energy, it takes the form of radiation per second launch into space is about 3.8 x 10 m joules, 2200000000th of a projected onto the earth. Sunlight is absorbed by the atmosphere reflection, after and 70% transmission to the ground. In spite of this, the earth was received in a year of the solar energy is still as high as 1.8 * 10 18 kw h. Since the earth formed creatures are mainly provided in the suns heat and light, and since ancient times people also know for sun dried objects, and as a way to save food, such as salt and dried salted fish. But under the fossil fuels to reduce, just to put solar further development. The use of solar energy has a passive use (thermal conversion) and the photoelectric conversion in two ways. Solar power a new renewable energy sources. Solar energy is in the broadest sense of the earth a lot of energy sources, such as wind energy, chemical energy, potential energy of water, and so on. The solar cell is refers to the use of the energy of sunlight power electromagnetic type. Compared to common batteries and circulating rechargeable batteries, solar cells belong to more energy conservation and environmental protection green products. Monocrystalline silicon solar battery photoelectric conversion efficiency is about 15%, the highest of 24%, this is all kinds of solar cells photoelectric conversion efficiency highest, but the production cost is very big, so it can not be used widely. Due to the commonly used single crystal silicon and waterproof resin toughened glass encapsulation, so its durable, generally can amount to 15 years, the service life of up to 25 years. The making craft of polycrystalline silicon solar cell and single crystal silicon solar cell is similar, but the polycrystalline silicon solar battery photoelectric conversion efficiency is to reduce a lot, the photoelectric conversion efficiency is about 12% (on July 1, 2004, Japans sharp market efficiency for 14.8% of the worlds highest efficiency of polycrystalline silicon solar cells). In terms of production cost is cheaper than monocrystalline silicon solar cells, the material is simple, save power consumption, the total production cost is low, so get a lot of development. In addition, the service life of the polycrystalline silicon solar cells will also shorter than monocrystalline silicon solar cells.As for the price performance ratio, monocrystalline silicon solar battery is slightly better. Amorphous silicon solar cell is a new kind of thin film type solar cell in 1976, it has to do with the method of making the monocrystalline silicon and polycrystalline silicon solar cell, a completely different process greatly simplified, little silicon material consumption, lower power consumption, its main advantage is in low light conditions can also generate electricity. But the amorphous silicon solar cell is the main problems the photoelectric conversion efficiency is low, the international advanced level of 10% or so, and is not stable, with the extension of time, the attenuation of conversion efficiency. Multivariate compound solar battery refers to is not made of single element semiconductor solar cells. Study of variety, most have not been industrialized production, mainly has the following kinds: a) cadmium sulphide solar cell b) gallium arsenide solar battery c) copper indium selenium solar cells (new band gap gradient Cu (In, Ga) Se2 thin film solar cells)Cu (In, Ga) Se2 is a kind of excellent performance sunlight absorption material, with a gradient band gap (between the conduction band and valence band linewidth.the) multivariate semiconductor material, can expand solar absorption spectrum, the photoelectric conversion efficiency can be improved. Based on it can design the photoelectric conversion efficiency than silicon thin film solar cells, thin film solar cells increased significantly. Can achieve the photoelectric conversion rate is 18%, and, so far, this kind of thin film solar cells, optical radiation cause performance degradation effect has not been found (SWE), the photoelectric conversion efficiency higher than that of commercial film solar panels about 50 75%, and in the thin film solar cells belong to the highest level of photoelectric conversion efficiency of the world. The service life of solar panels by the cell, toughened glass, EVA and TPT material decisions, such as tend to use better materials manufacturers to make to the service life of the panels can reach 25 years, but with the influence of environment, the material of solar panels will be as the change of time and aging. In general use power attenuation 30% 20 years, for 25 years power attenuation 70%. Solar cell is a light have response and can convert light energy into electrical devices. Can produce the material, there are many kinds of photovoltaic effect, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, copper indium selenium, etc. Their power generation principle of basic same, now in crystalline silicon, for example to describe the light power generation process. P-type crystalline silicon after doped phosphorus available N type silicon, forming a p-n junction. When light solar cell surface, part of photons absorbed by the silicon material; Photon energy transfer to the silicon atom, make electronic happened more moved, a free electron concentration on both sides of p-n junction formed the potential difference, when external processing circuit, under the action of the voltage, there will be a current through the external circuit to produce the output power. The essence of this process is: the process of the photon energy into electricity. Solar energy as a new kind of energy, compared with conventional energy, it has three characteristics: first, it is the most abundant energy we can use. It is estimated that in the past 1.1 billion years long, the sun consumes 2% of its energy. Future is enough to supply the earth humans, the use of billions of years, are inexhaustible, an inexhaustible. Second: the earth, no matter where there is solar energy, can be on the development and utilization, there is no transport problem, especially for traffic underdeveloped rural areas, islands and remote areas had more use value. Third: solar energy is a kind of clean energy. During the development and utilization, wont produce waste residues, waste water, waste gas, no noise, more will not affect the ecological balance. Absolutely not cause pollution and pollution. Believe that the future solar energy use will be widely used in our daily life.太阳能电池板 太阳能电池板是通过吸收太阳光,将太阳辐射能通过光电效应或者光化学效应直接或间接转换成电能的装置,大部分太阳能电池板的主要材料为“硅”,但因制作成本很大,以致于它还不能被大量广泛和普遍地使用。太阳能:太阳是一个巨大的能源,它以光辐射的形式每秒钟向太空发射约3.810M焦耳的能量,有22亿分之一投射到地球上。太阳光被大气层反射、吸收之后,还有70%透射到地面。尽管如此,地球上一年中接受到的太阳能仍然高达1.81018kWh。自地球形成生物就主要以太阳提供的热和光生存,而自古人类也懂得以阳光晒干物件,并作为保存食物的方法,如制盐和晒咸鱼等。但在化石燃料减少下,才有意把太阳能进一步发展。太阳能的利用有被动式利用(光热转换)和光电转换两种方式。太阳能发电一种新兴的可再生能源。广义上的太阳能是地球上许多能量的来源,如风能,化学能,水的势能等等。太阳能电池是指利用太阳光的能量发电的电磁种类。相对于普通电池和可循环充电电池来说,太阳能电池属于更节能环保的绿色产品。单晶硅太阳能电池的光电转换效率为15%左右,最高的达到24%,这是所有种类的太阳能电池中光电转换效率最高的,但制作成本很大,以致于它还不能被普遍地使用。由于单晶硅一般采用钢化玻璃以及防水树脂进行封装,因此其坚固耐用,使用寿命一般可达15年,最高可达25年。多晶硅太阳电池的制作工艺与单晶硅太阳电池差不多,但是多晶硅太阳能电池的光电转换效率则要降低不少,其光电转换效率约12%左右 (2004年7月1日日本夏普上市效率为14.8%的世界最高效率多晶硅太阳能电池)。 从制作成本上来讲,比单晶硅太阳能电池要便宜一些,材料制造简便,节约电耗,总的生产成本较低,因此得到大量发展。此外,多晶硅太阳能电池的使用寿命也要比单晶硅太阳能电池短。从性能价格比来讲,单晶硅太阳能电池还略好。非晶硅太阳电池是1976年出现的新型薄膜式太阳电池,它与单晶硅和多晶硅太阳电池的制作方法完全不同,工艺过程大大简化,硅材料消耗很少,电耗更低,它的主要优点是在弱光条件也能发电。但非晶硅太阳电池存在的主要问题是光电转换效率偏低,国际先进水平为10%左右,且不够稳定,随着时间的延长,其转换效率衰减。多元化合物太阳电池指不是用单一元素半导体材料制成的太阳电池。各国研究的品种繁多,大多数尚未工业化生产,主要有以下几种:a)硫化镉太阳能电池b)砷化镓太阳能电池c)铜铟硒太阳
