太陽(yáng)電池經(jīng)過(guò)制絨、擴(kuò)散及PECVD等工序后，已經(jīng)制成PN結(jié)，可以在光照下產(chǎn)生電流，為了將產(chǎn)生的電流導(dǎo)出，需要在電池表面上制作正、負(fù)兩個(gè)電極。制造電極的方法很多，而絲網(wǎng)印刷是目前制作太陽(yáng)電池電極**普遍的一種生產(chǎn)工藝。絲網(wǎng)印刷是采用壓印的方式將預(yù)定的圖形印刷在基板上，該設(shè)備由電池背面銀鋁漿印刷、電池背面鋁漿印刷和電池正面銀漿印刷三部分組成。其工作原理為：利用絲網(wǎng)圖形部分網(wǎng)孔透過(guò)漿料，用刮刀在絲網(wǎng)的漿料部位施加一定壓力，同時(shí)朝絲網(wǎng)另一端移動(dòng)。油墨在移動(dòng)中被刮刀從圖形部分的網(wǎng)孔中擠壓到基片上。由于漿料的粘性作用使印跡固著在一定范圍內(nèi)，印刷中刮板始終與絲網(wǎng)印版和基片呈線性接觸，接觸線隨刮刀移動(dòng)而移動(dòng)，從而完成印刷行程。遼寧雙晶太陽(yáng)能電池片生產(chǎn)太陽(yáng)能電池板內(nèi)部構(gòu)造.</p><div

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(wàn)個(gè)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(jià)的濃度約為1%的氫氧化鈉稀溶液來(lái)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(guò)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)。 </p><p> 三、擴(kuò)散制結(jié) </p> <p> 太陽(yáng)能電池需要一個(gè)大面積的PN結(jié)以實(shí)現(xiàn)光能到電能的轉(zhuǎn)換，而擴(kuò)散爐即為制造太陽(yáng)能電池PN結(jié)的**設(shè)備。管式擴(kuò)散爐主要由石英舟的上下載部分、廢氣室、爐體部分和氣柜部分等四大部分組成。擴(kuò)散一般用三氯氧磷液態(tài)源作為擴(kuò)散源。把P型硅片放在管式擴(kuò)散爐的石英容器內(nèi)，在850---900攝氏度高溫下使用氮?dú)鈱⑷妊趿讕胧⑷萜?，通過(guò)三氯氧磷和硅片進(jìn)行反應(yīng)，得到磷原子。經(jīng)過(guò)一定時(shí)間，磷原子從四周進(jìn)入硅片的表面層，并且通過(guò)硅原子之間的空隙向硅片內(nèi)部滲透擴(kuò)散，形成了N型半導(dǎo)體和P型半導(dǎo)體的交界面，也就是PN結(jié)。這種方法制出的PN結(jié)均勻性好,方塊電阻的不均勻性小于百分之十,少子壽命可大于10ms。制造PN結(jié)是太陽(yáng)電池生產(chǎn)**基本也是**關(guān)鍵的工序。因?yàn)檎荘N結(jié)的形成，才使電子和空穴在流動(dòng)后不再回到原處，這樣就形成了電流，用導(dǎo)線將電流引出，就是直流電。太陽(yáng)能電池片含鉛嗎？？？</p><div

①短路電流(isc)：當(dāng)將太陽(yáng)能電池的正負(fù)極短路、使u=0時(shí)，此時(shí)的電流就是電池片的短路電流，短路電流的單位是安培(a)，短路電流隨著光強(qiáng)的變化而變化。 </p> <p>

④峰值電壓(um)：峰值電壓也叫比較大工作電壓或比較好工作電壓。峰值電壓是指太陽(yáng)能電池片輸出比較大功率時(shí)的工作電壓，峰值電壓的單位是v。峰值電壓不隨電池片面積的增減而變化，一般為0.45～0.5v，典型值為0.48v。 </p> <p> <br /> </p> <p> <br /> 太陽(yáng)能電池板能做的**小尺寸？吉林非晶硅太陽(yáng)能電池片組件</p><p
