答：太陽能電池是基于半導(dǎo)體的光伏效應(yīng)將太陽輻射直接轉(zhuǎn)換為電能的半導(dǎo)體器件?，F(xiàn)在商品化的太陽能電池主要有以下幾種類型：單晶硅太陽能電池、多晶硅太陽能電池、非晶硅太陽能電池，北京雙晶硅太陽能電池片一片多少錢，目前還有碲華鎘電池、銅銦硒電池、納米氧化鈦敏化電池、多晶硅薄膜太陽能電池及有機太陽能電池等。 </p> <p> 晶體硅（單晶、多晶）太陽能電池需要高純度的硅原料，一般要求純度至少是99，北京雙晶硅太陽能電池片一片多少錢.99998%，也就是一千萬個硅原子中**多允許2個雜質(zhì)原子存在。硅材料是用二氧化硅（SiO2，也就是我們所熟悉的沙子）作為原料，將其熔化并除去雜質(zhì)就可制取粗級硅，北京雙晶硅太陽能電池片一片多少錢。從二氧化硅到太陽能電池片，涉及多個生產(chǎn)工藝和過程，一般大致分為：二氧化硅—>冶金級硅—>高純?nèi)葰涔琛?高純度多晶硅—>單晶硅棒或多晶硅錠—>硅片—>太陽能電池片。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京雙晶硅太陽能電池片一片多少錢" src="http://tyunfile.71360.com/UploadFile/Wuxiskt/637188253428994140/8851994.jpg"></div><p> 多晶硅太陽電他的出現(xiàn)主要是為了降低成本，其優(yōu)點是能直接制備出適于規(guī)?；a(chǎn)的大尺寸方型硅錠，設(shè)備比較簡單，制造過程簡單、省電、節(jié)約硅材料，對材質(zhì)要求也較低。晶界及雜質(zhì)影響可通過電池加工工藝進行改善；由于材質(zhì)和晶界影響，電池效率較低。電池工藝主要采用吸雜、鈍化、背場等技術(shù)。 </p> <p> 常規(guī)鋁吸雜工藝是在電池的背面蒸鍍鋁膜后經(jīng)過燒結(jié)形成，也可同時形成電池的背場。近幾年在吸雜上的工作證明，它對***單晶硅太陽電池及多晶硅太陽電池都會產(chǎn)生一定的作用。 </p> <p> 鈍化是提高多晶硅質(zhì)量的有效方法。一種方法是采用氫鈍化，鈍化硅體內(nèi)的懸掛鍵等缺點。在晶體生長中受應(yīng)力等影響造成缺點越多的硅材料，氫鈍化的效果越好。氫鈍化可采用離子注入或等離子體處理。在多晶硅太陽電池表面采用PECVD法鍍上一層氮化硅減反射膜，由于硅烷分解時產(chǎn)生氫離子，對多晶硅可產(chǎn)生氫鈍化的效果。 </p> <p> 在***太陽電池上常采用表面氧鈍化的技術(shù)來提高太陽電他的效率，近年來在光伏級的晶體硅材料上使用也有明顯的效果，尤其采用熱氧化法效果更明顯。使用PECVD法在更低的溫度下進行表面氧化，近年來也被使用，具有一定的效果。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

一、太陽能電池是通過光電效應(yīng)或者光化學(xué)效應(yīng)直接把光能轉(zhuǎn)化成電能的裝置。以光電效應(yīng)工作的晶硅太陽能電池為主流，而以光化學(xué)效應(yīng)工作的薄膜電池實施太陽能電池則還處于萌芽階段。 </p> <p> 二、太陽電池是一種可以將能量轉(zhuǎn)換的光電元件，其基本構(gòu)造是運用P型與N型半導(dǎo)體接合而成的。半導(dǎo)體**基本的材料是“硅”，它是不導(dǎo)電的，但如果在半導(dǎo)體中摻入不同的雜質(zhì)，就可以做成P型與N型半導(dǎo)體，再利用P型半導(dǎo)體有個空穴。 </p> <p> 三、與N型半導(dǎo)體多了一個自由電子的電位差來產(chǎn)生電流，所以當(dāng)太陽光照射時，光能將硅原子中的電子激發(fā)出來，而產(chǎn)生電子和空穴的對流，這些電子和空穴均會受到內(nèi)建電位的影響，分別被N型及P型半導(dǎo)體吸引，而聚集在兩端。 </p> <p> 四、此時外部如果用電極連接起來，形成一個回路，這就是太陽電池發(fā)電的原理。 </p><div
