一般來(lái)說(shuō)，單個(gè)的太陽(yáng)能電池不能直接作為電源使用，在實(shí)際應(yīng)用中，是將幾片或幾十片單個(gè)的太陽(yáng)能電池串聯(lián)或并聯(lián)起來(lái)，組成太陽(yáng)能方車，這樣才能得到較大的能力。在太陽(yáng)能電池方陣中還裝有蓄電池，那是為了保證在夜晚或陰雨天太陽(yáng)不露面時(shí)能連續(xù)供電的一種儲(chǔ)能裝置。當(dāng)太陽(yáng)光照射時(shí)，太陽(yáng)能電池產(chǎn)生的電能不停地滿足當(dāng)時(shí)的需要，而且還可多提供一些電能儲(chǔ)存于蓄電池內(nèi)。 </p> <p> 太陽(yáng)能電池首先是在空間飛行中得到應(yīng)用的。1958年，美國(guó)發(fā)射了***顆太陽(yáng)能電池供電的“先鋒”1號(hào)衛(wèi)星，從此，各式各樣的衛(wèi)星和宇宙飛船都安置了布滿太陽(yáng)能電池的“翅膀”，使得它們能在太空中盡情遨游。由于衛(wèi)星和宇宙飛船上的電子儀器和設(shè)備都要使用大量的電能，但它們對(duì)電源的要求十分苛刻，既要重量輕，使用壽命長(zhǎng)，能連續(xù)不斷地工作，又要能承受各種沖擊、碰撞和振動(dòng)的影響，而太陽(yáng)電池在這幾方面都有出色的表現(xiàn)，自然而然便成了合適的中選者。當(dāng)衛(wèi)星向著太陽(yáng)飛行時(shí)，電池方陣受陽(yáng)光照射產(chǎn)生電能，供應(yīng)衛(wèi)生用電，同時(shí)向衛(wèi)星上的蓄電池充電；當(dāng)衛(wèi)星背著太陽(yáng)飛行時(shí)，蓄電池就放電，使衛(wèi)星上的儀器保持連續(xù)工作。 </p><p> 太陽(yáng)能電池的輸出功率一方面與外部環(huán)境有關(guān)，另一方面與負(fù)載情況有關(guān)，因此光伏電池輸出功率必須加以控制，使它在各種情況下都輸出比較大的功率。 </p> <p> 1、電池測(cè)試：電池測(cè)試即通過測(cè)試電池的輸出參數(shù)的大小對(duì)其進(jìn)行分類，以提高電池的利用率，做出量合格的電池組件。 </p> <p> 2、正面焊接：是將匯流帶焊接到電池正面（負(fù)極）的主柵線上，匯流帶為鍍錫的銅帶，將焊帶以多點(diǎn)的形式點(diǎn)焊在主柵線上。 </p> <p> 3、背面串接：背面焊接是將3 </p> <p> 6片電池串接在一起形成一個(gè)組件串。 </p> <p> 4、層壓敷設(shè)：背面串接好且經(jīng)過檢驗(yàn)合格后，將組件串、玻璃和切割好的EVA 、玻璃纖維、背板按照一定的層次敷設(shè)好，準(zhǔn)備層壓。玻璃事先涂一層試劑（primer）以增加玻璃和EVA的粘接強(qiáng)度。敷設(shè)時(shí)保證電池串與玻璃等材料的相對(duì)位置，調(diào)整好電池間的距離，為層壓打好基礎(chǔ)。 </p> <p> 5、件層壓：將敷設(shè)好的電池放入層壓機(jī)內(nèi)，通過抽真空將組件內(nèi)的空氣抽出，然后加熱使EVA熔化將電池、玻璃和背板粘接在一起，***冷卻取出組件。 </p> <p> 6、修邊：層壓時(shí)EVA熔化后由于壓力而向外延伸固化形成毛邊，所以層壓完畢應(yīng)將其切除。 </p> <p> 7、裝框：類似與給玻璃裝一個(gè)鏡框，給玻璃組件裝鋁框，增加組件的強(qiáng)度，進(jìn)一步的密封電池組件，延長(zhǎng)電池的使用壽命。 </p> <p> <br /> 太陽(yáng)能電池片Eta17.9%代表什么？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

答：太陽(yáng)能電池是基于半導(dǎo)體的光伏效應(yīng)將太陽(yáng)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(yáng)能電池主要有以下幾種類型：?jiǎn)尉Ч杼?yáng)能電池、多晶硅太陽(yáng)能電池、非晶硅太陽(yáng)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(yáng)能電池及有機(jī)太陽(yáng)能電池等。 </p> <p> 晶體硅（單晶、多晶）太陽(yáng)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(wàn)個(gè)硅原子中**多允許2個(gè)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(jí)硅。從二氧化硅到太陽(yáng)能電池片，涉及多個(gè)生產(chǎn)工藝和過程，一般大致分為：二氧化硅—>冶金級(jí)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(yáng)能電池片。太陽(yáng)能電池板的種類?。?！遼寧太陽(yáng)能電池片生產(chǎn)</p><p style="text-indent:25px">太陽(yáng)能電池片經(jīng)過幾道工序生產(chǎn)？吉林單晶太陽(yáng)能電池片進(jìn)口</p><p> 1、開路電壓 </p> <p> （1）、開路電壓UOC：即將太陽(yáng)能電池置于AM1.5光譜條件、100 mW/cm2的光源強(qiáng)度照射下，在兩端開路時(shí)，太陽(yáng)能電池的輸出電壓值。 </p> <p> 2、短路電流 </p> <p> （1）、短路電流ISC：就是將太陽(yáng)能電池置于AM1.5光譜條件、100 mW/cm2的光源強(qiáng)度照射下，在輸出端短路時(shí)，流過太陽(yáng)能電池兩端的電流值。 </p> <p> 3、比較大輸出功率 </p> <p> （1）、太陽(yáng)能電池的工作電壓和電流是隨負(fù)載電阻而變化的，將不同阻值所對(duì)應(yīng)的工作電壓和電流值做成曲線就得到太陽(yáng)能電池的伏安特性曲線。 </p> <p> （2）、如果選擇的負(fù)載電阻值能使輸出電壓和電流的乘積比較大，即可獲得比較大輸出功率，用符號(hào)Pm表示。此時(shí)的工作電壓和工作電流稱為比較好工作電壓和比較好工作電流，分別用符號(hào)Um和Im表示。吉林單晶太陽(yáng)能電池片進(jìn)口</p><p
