求幾篇有關(guān)太陽能電池方面的英文文獻及其翻譯

【專家解說】：太陽光照在半導(dǎo)體p-n結(jié)上，形成新的空穴-電子對，在p-n結(jié)電場的作用下，空穴由n區(qū)流向p區(qū)，電子由p區(qū)流向n區(qū)，接通電路后就形成電流。這就是光電效應(yīng)太陽能電池的工作原理。 一、太陽能發(fā)電方式太陽能發(fā)電有兩種方式，一種是光—熱—電轉(zhuǎn)換方式，另一種是光—電直接轉(zhuǎn)換方式。 （1） 光—熱—電轉(zhuǎn)換方式通過利用太陽輻射產(chǎn)生的熱能發(fā)電，一般是由太陽能集熱器將所吸收的熱能轉(zhuǎn)換成工質(zhì)的蒸氣，再驅(qū)動汽輪機發(fā)電。前一個過程是光—熱轉(zhuǎn)換過程；后一個過程是熱—電轉(zhuǎn)換過程，與普通的火力發(fā)電一樣.太陽能熱發(fā)電的缺點是效率很低而成本很高，估計它的投資至少要比普通火電站貴5～10倍.一座1000MW的太陽能熱電站需要投資20～25億美元，平均1kW的投資為2000～2500美元。因此，目前只能小規(guī)模地應(yīng)用于特殊的場合，而大規(guī)模利用在經(jīng)濟上很不合算，還不能與普通的火電站或核電站相競爭。 （2） 光—電直接轉(zhuǎn)換方式該方式是利用光電效應(yīng)，將太陽輻射能直接轉(zhuǎn)換成電能，光—電轉(zhuǎn)換的基本裝置就是太陽能電池。太陽能電池是一種由于光生伏特效應(yīng)而將太陽光能直接轉(zhuǎn)化為電能的器件，是一個半導(dǎo)體光電二極管，當太陽光照到光電二極管上時，光電二極管就會把太陽的光能變成電能，產(chǎn)生電流。當許多個電池串聯(lián)或并聯(lián)起來就可以成為有比較大的輸出功率的太陽能電池方陣了。太陽能電池是一種大有前途的新型電源，具有永久性、清潔性和靈活性三大優(yōu)點.太陽能電池壽命長，只要太陽存在，太陽能電池就可以一次投資而長期使用；與火力發(fā)電、核能發(fā)電相比，太陽能電池不會引起環(huán)境污染；太陽能電池可以大中小并舉，大到百萬千瓦的中型電站，小到只供一戶用的太陽能電池組，這是其它電源無法比擬的 The sun light in the semiconductor pn junction, the formation of a new hole - electron pairs in the pn junction of the role of the electric field, the hole flow from the n area p areas, electronic flow n by p zone area, connected to the circuit after the current form. This is the photoelectric effect of the working principle of solar cells. First, the way solar power generation solar power in two ways, one is light - heat - electricity conversion mode, and the other is light - electric direct conversion approach. (1) light - heat - electricity conversion of solar radiation through the use of thermal energy generated by power generation, is normally provided by solar collectors to heat absorbed by refrigerant into steam, and steam turbine-driven power generation. A process before it is light - heat conversion process; after a process of heat - electricity conversion process, as with an ordinary power. Drawback of solar thermal power generation is highly inefficient and costly, it is estimated that at least its investment than the average fire Power your 5 to 10 times. a 1000MW of solar thermal power plants need to invest 20 to 25 billion U.S. dollars, an average of 1kW of investment from 2000 to 2500 U.S. dollars. Therefore, at present, can only be applied to small-scale special occasions, and large-scale use in the economy is very uneconomical, but also with ordinary competing power plant or nuclear power plants. (2) Optical - Electric direct conversion approach is the use of the photoelectric effect, solar radiation will be directly converted into electrical energy, light - the basic power conversion is the solar cell device. Solar cell is a kind of volts due to the effects of photovoltaic solar energy will be directly converted into electrical energy device is a semiconductor photodiode, when the sun's light to the photodiode, the photodiode will be the sun's light energy into power, resulting in current. When many cells are connected in series or parallel can be up to become a relatively large output power of a square solar cells. Solar cells is a promising new type of power supply, with a permanent, clean and flexibility of the three major advantages. Solar battery life long, as long as there is sun, solar cells can be an investment in long-term use; and thermal power, nuclear power generation compared to solar cells will not cause environmental pollution; Xinhuanet both solar cells can be as large as one million kilowatts of medium-sized power plants, small enough to only use a solar battery, which is unmatched by other power 分給我吧 看 Harnessing the Power of the Sun With rising fuel costs, climate change concerns and a growing demand for electricity, renewable energy resources such as solar power are becoming an increasingly valuable part of the world's energy mix. Around the globe, businesses and homeowners are harnessing the power of the earth's most abundant natural resource - sunlight - to provide energy using solar power. GE's solar electric power systems and products offer high quality, reliable power generation for residential, commercial and industrial applications. By partnering with the sun, solar energy can supply local power for on-and off-grid applications with zero noise pollution and air emissions. 掌握太陽 與不斷上漲的燃料成本，氣候變化的關(guān)注和對電力的需求日益增加，可再生能源資源，如太陽能發(fā)電正在成為越來越有價值的一部分，世界上能源結(jié)構(gòu)。全球各地的企業(yè)和業(yè)主都掌握了地球上最豐富的天然資源-陽光-提供能源利用太陽能發(fā)電。 通用電氣公司的太陽能電力系統(tǒng)和產(chǎn)品提供高品質(zhì)，可靠發(fā)電的住宅，商業(yè)和工業(yè)應(yīng)用。通過與太陽，太陽能可以提供當?shù)氐碾娏?，供市民和離網(wǎng)應(yīng)用與零噪音污染和廢氣排放。 這個不行的話，你去這里看下，應(yīng)該可以~ http://www.sciencenet.cn/bbs/showpost.aspx?id=43847&yin=43847 參考資料： http://www.sciencenet.cn/bbs/showpost.aspx?id=43847&yin=43847 分現(xiàn)在給我吧
