為實(shí)現(xiàn)燒結(jié)段的溫度尖峰，需在很短的爐膛空間內(nèi)布置足夠的加熱功率。有短波孿管和短波單管兩種結(jié)構(gòu)可以選擇，其線性功率密度均達(dá)到60kW/m2。雖然短波孿管擁有更高的單根功率(相當(dāng)于兩根單管并聯(lián))，但由于其制造工藝復(fù)雜，對(duì)石英玻璃管的質(zhì)量要求更高，制造成本約是單管的2.5倍。因此，在實(shí)際使用中，大多采用單管。 </p> <p> 2、紅外輻射吸收光譜 </p> <p> 當(dāng)紅外輻射能量被工件吸收時(shí)，該物質(zhì)所特有的吸收光譜需與發(fā)射光譜相匹配，才能在**短時(shí)間內(nèi)比較大效率地吸收輻射能。因此，在燒結(jié)的不同階段，所選用的紅外石英燈管也是不同的。在烘干段，要讓有機(jī)溶劑和水分迅速揮發(fā)，采用中波管輔助熱風(fēng)加熱是正確的;在預(yù)燒段，要讓基片獲得充分均勻的預(yù)熱，中波管良好的紅外輻射、均衡的吸收及穿透能力，正好符合要求;在燒結(jié)段，必須在極短時(shí)間內(nèi)使基片達(dá)到共晶溫度，只有短波管能做到這一點(diǎn)。 </p> <p> 3、加熱管的固定方式 </p> <p> 燒結(jié)段的溫度峰值在850℃左右，此時(shí)燈管的表面溫度將達(dá)到1100℃，接近石英管的使用極限，稍微過熱產(chǎn)生氣孔就會(huì)立刻燒毀燈管。而在燈管的引出導(dǎo)線部位，由于焊接導(dǎo)線的金屬片和石英玻璃密封在一起，二者熱膨脹系數(shù)不一致，如果此處溫度過高就會(huì)產(chǎn)生應(yīng)力裂紋，造成燈管漏氣北京雙面太陽能電池片太陽能電池片的生產(chǎn)工藝?</p><div

用來粘結(jié)固定鋼化玻璃和發(fā)電主體（如電池片），透明EVA材質(zhì)的優(yōu)劣直接影響到組件的壽命，暴露在空氣中的EVA易老化發(fā)黃，從而影響組件的透光率。 </p> <p> 從而影響組件的發(fā)電質(zhì)量除了EVA本身的質(zhì)量外，組件廠家的層壓工藝影響也是非常大的，如EVA膠連度不達(dá)標(biāo)，EVA與鋼化玻璃、背板粘接強(qiáng)度不夠，都會(huì)引起EVA提早老化，影響組件壽命。 </p> <p> 3、電池片主要作用就是發(fā)電，發(fā)電主體市場(chǎng)上主流的是晶體硅太陽電池片、薄膜太陽能電池片，兩者各有優(yōu)劣。 </p> <p> 4、EVA作用如上，主要粘結(jié)封裝發(fā)電主體和背板 </p> <p> 5、背板作用，密封、絕緣、防水（一般都用TPT、TPE等材質(zhì)必須耐老化，大部分組件廠家都質(zhì)保25年，鋼化玻璃，鋁合金一般都沒問題，關(guān)鍵就在與背板和***是否能達(dá)到要求。） </p> <p> 6、鋁合金保護(hù)層壓件，起一定的密封、支撐作用 </p> <p> 7、接線盒保護(hù)整個(gè)發(fā)電系統(tǒng)，起到電流中轉(zhuǎn)站的作用，如果組件短路接線盒自動(dòng)斷開短路電池串，防止燒壞整個(gè)系統(tǒng)。 </p> <p> 8、*** 密封作用，用來密封組件與鋁合金邊框、組件與接線盒交界處。有些公司使用雙面膠條、泡棉來替代***，國(guó)內(nèi)普遍使用***，工藝簡(jiǎn)單，方便，易操作，而且成本很低。 </p> <p> 擴(kuò)展資料 </p> <p> <br /> </p><p> 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(shí)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(yùn)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(gè)空穴。 </p> <p> 三、與N型半導(dǎo)體多了一個(gè)自由電子的電位差來產(chǎn)生電流，所以當(dāng)太陽光照射時(shí)，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(duì)流，這些電子和空穴均會(huì)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(shí)外部如果用電極連接起來，形成一個(gè)回路，這就是太陽電池發(fā)電的原理。太陽能電池片**大功率是多少？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吉林雙晶硅太陽能電池片生產(chǎn),太陽能電池片"
