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(jìn)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(jìn)行一般的化學(xué)清洗。經(jīng)過表面準(zhǔn)備的硅片都不宜在水中久存，以防沾污，應(yīng)盡快擴(kuò)散制結(jié)。黑龍江太陽能電池片公司太陽能電池板能做的**小尺寸？</p><div

</p> <p> 一、硅片檢測 </p> <p> 硅片是太陽能電池片的載體，硅片質(zhì)量的好壞直接決定了太陽能電池片轉(zhuǎn)換效率的高低，因此需要對來料硅片進(jìn)行檢測。該工序主要用來對硅片的一些技術(shù)參數(shù)進(jìn)行在線測量，這些參數(shù)主要包括硅片表面不平整度、少子壽命、電阻率、P/N型和微裂紋等。該組設(shè)備分自動上下料、硅片傳輸、系統(tǒng)整合部分和四個檢測模塊。其中，光伏硅片檢測儀對硅片表面不平整度進(jìn)行檢測,同時檢測硅片的尺寸和對角線等外觀參數(shù);微裂紋檢測模塊用來檢測硅片的內(nèi)部微裂紋;另外還有兩個檢測模組，其中一個在線測試模組主要測試硅片體電阻率和硅片類型，另一個模塊用于檢測硅片的少子壽命。在進(jìn)行少子壽命和電阻率檢測之前，需要先對硅片的對角線、微裂紋進(jìn)行檢測，并自動剔除破損硅片。硅片檢測設(shè)備能夠自動裝片和卸片，并且能夠?qū)⒉缓细衿贩诺焦潭ㄎ恢茫瑥亩岣邫z測精度和效率。 </p><p> P型和N型都可以做電池片。 </p> <p> 在p型半導(dǎo)體材料上擴(kuò)散磷元素，形成n+/p型結(jié)構(gòu)的太陽電池即為P型硅片； </p> <p> 在N型半導(dǎo)體材料上注入硼元素，形成p+/n型結(jié)構(gòu)的太陽電池即為n型硅片； </p> <p> 目前光伏行業(yè)主流產(chǎn)品是P型硅片，P型硅片制作工藝簡單，成本較低，N型硅片通常少子壽命較大，電池效率可以做得更高，但是工藝更加復(fù)雜。N型硅片摻磷元素，磷與硅相溶性差，拉棒時磷分布不均，P型硅片摻硼元素，硼與硅分凝系數(shù)相當(dāng)，分散均勻度容易控制。 </p> <p> 歡迎您的來電?。。?太陽能電池片鋁框規(guī)格?。?！</p><div

經(jīng)過絲網(wǎng)印刷后的硅片，不能直接使用，需經(jīng)燒結(jié)爐快速燒結(jié)，將有機(jī)樹脂粘合劑燃燒掉，剩下幾乎純粹的、由于玻璃質(zhì)作用而密合在硅片上的銀電極。當(dāng)銀電極和晶體硅在溫度達(dá)到共晶溫度時，晶體硅原子以一定的比例融入到熔融的銀電極材料中去，從而形成上下電極的歐姆接觸，提高電池片的開路電壓和填充因子兩個關(guān)鍵參數(shù)，使其具有電阻特性，以提高電池片的轉(zhuǎn)換效率。 </p> <p> 燒結(jié)爐分為預(yù)燒結(jié)、燒結(jié)、降溫冷卻三個階段。預(yù)燒結(jié)階段目的是使?jié){料中的高分子粘合劑分解、燃燒掉，此階段溫度慢慢上升;燒結(jié)階段中燒結(jié)體內(nèi)完成各種物理化學(xué)反應(yīng)，形成電阻膜結(jié)構(gòu)，使其真正具有電阻特性，該階段溫度達(dá)到峰值;降溫冷卻階段，玻璃冷卻硬化并凝固，使電阻膜結(jié)構(gòu)固定地粘附于基片上。太陽能電池片能不能不封裝？吉林單晶硅太陽能電池片</p><p
