半導(dǎo)體的摻雜擴散，主要是依靠了離子從高濃度像低濃度區(qū)域擴散的原理。在太陽能的硅片中，把雜質(zhì)原子的氣相源靠近硅片，加熱后，使其慢慢擴散，雜質(zhì)原子會慢慢的深入硅片中，濃度從硅片邊緣到內(nèi)部是逐漸降低的。 </p> <p> <br /> </p> <p> 半導(dǎo)體中的摻雜是指在半導(dǎo)體硅中摻入磷或鎵可以得n型或p型半導(dǎo)體材料，由此制出各式各樣的半導(dǎo)體器件。在一些無機固體化合物中摻入不同的金屬離子，可以得到不同性質(zhì)的發(fā)光材料，如氧化釔(III)中摻入銪(III)離子可以得到發(fā)紅光的熒光材料。 </p><p style="text-indent:25px">太陽電池的主柵是不確定數(shù)目的，這都是隨時代而變換的，以前是兩主柵，后面有三主柵，還有五主柵，其實也有研究過無主柵的，主柵的主要作用與細柵類似，都是收集載流子，但是呢，主柵的數(shù)量及寬度是要追求一個比較好化的，既要滿足足夠多和粗來講全部的有效載流子收集起來，又要盡可能的少和細來盡量減少對太陽光的阻擋作用。因此需要在這之間找一個平衡。因為背面不涉及到采光問題（普通電池），所以一般設(shè)計成全鋁背場，但是也得要載流子導(dǎo)出來啊，所以會有背銀的存在，全鋁背場和背銀都是背電極。主柵和背面的背銀都是為了焊接用的，你看到的封裝好的電池，前面的主柵上是焊了一條焊帶的，背面也是，背銀的作用就是為焊帶焊接導(dǎo)出載流子而用的，需要注意的是細柵和主柵是絲網(wǎng)印刷印上去的，而你看到封裝好的電池的主柵上覆蓋了一層焊帶，這是焊上去的。至于你說的正極負極，這跟柵線的數(shù)目沒有關(guān)系，這主要與電池片的類型有關(guān)，P型電池片的正極是背電極，前電極（主柵細柵）就是負極。太陽能電池片并聯(lián)電阻是多少?</p><div

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。現(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，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99.99998%，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。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。太陽能電池板能做的**小尺寸？吉林雙晶太陽能電池片結(jié)構(gòu)</p><p style="text-indent:25px">太陽能電池的主要參數(shù)是什么？北京太陽能電池片</p><p> 二、表面制絨 </p> <p> 單晶硅絨面的制備是利用硅的各向異性腐蝕，在每平方厘米硅表面形成幾百萬個四面方錐體也即金字塔結(jié)構(gòu)。由于入射光在表面的多次反射和折射，增加了光的吸收，提高了電池的短路電流和轉(zhuǎn)換效率。硅的各向異性腐蝕液通常用熱的堿性溶液，可用的堿有氫氧化鈉，氫氧化鉀、氫氧化鋰和乙二胺等。大多使用廉價的濃度約為1%的氫氧化鈉稀溶液來制備絨面硅，腐蝕溫度為70-85℃。為了獲得均勻的絨面，還應(yīng)在溶液中酌量添加醇類如乙醇和異丙醇等作為絡(luò)合劑，以加快硅的腐蝕。制備絨面前，硅片須先進行初步表面腐蝕，用堿性或酸性腐蝕液蝕去約20～25μm，在腐蝕絨面后，進行一般的化學(xué)清洗。經(jīng)過表面準備的硅片都不宜在水中久存，以防沾污，應(yīng)盡快擴散制結(jié)。北京太陽能電池片</p><p
