半導(dǎo)體的摻雜擴(kuò)散，主要是依靠了離子從高濃度像低濃度區(qū)域擴(kuò)散的原理。在太陽(yáng)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(kuò)散，雜質(zhì)原子會(huì)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(wú)機(jī)固體化合物中摻入不同的金屬離子，吉林硅太陽(yáng)能電池片好壞，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，吉林硅太陽(yáng)能電池片好壞。太陽(yáng)能電池片的技術(shù)參數(shù)，吉林硅太陽(yáng)能電池片好壞?。。〖止杼?yáng)能電池片好壞</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(shí)，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(gè)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(gè)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。吉林硅太陽(yáng)能電池片好壞太陽(yáng)能電池片鋁框規(guī)格?。?！</p><div

src="http://tyunfile.71360.com/UploadFile/Wuxiskt/637188253428994140/8851994.jpg"></div><p> 在光伏組件中，電池片逆電流過大的話，如果某塊光伏組件被陰影遮擋，那么電流就會(huì)回流將電池組件燒壞，因此光伏組件后面的接線盒里都需要安裝防反和旁路二極管以防止逆電流。 </p> <p> <br /> </p> <p> 太陽(yáng)能(solar energy)，是指太陽(yáng)的熱輻射能(參見熱能傳播的三種方式)，主要表現(xiàn)就是常說的太陽(yáng)光線。在現(xiàn)代一般用作發(fā)電或者為熱水器提供能源。自地球上生命誕生以來，就主要以太陽(yáng)提供的熱輻射能生存，而自古人類也懂得以陽(yáng)光曬干物件，并作為制作食物的方法，如制鹽和曬咸魚等。在化石燃料日趨減少的情況下，太陽(yáng)能已成為人類使用能源的重要組成部分，并不斷得到發(fā)展。太陽(yáng)能的利用有光熱轉(zhuǎn)換和光電轉(zhuǎn)換兩種方式，太陽(yáng)能發(fā)電是一種新興的可再生能源。廣義上的太陽(yáng)能也包括地球上的風(fēng)能、化學(xué)能、水能等。 </p><p> 太陽(yáng)能電池也能用于飛機(jī)，世界上***架用太陽(yáng)能電池作動(dòng)力的飛機(jī)“太陽(yáng)挑戰(zhàn)者”號(hào)已經(jīng)試飛成功，共飛行4個(gè)半小時(shí)，飛行高度達(dá)4000米，飛行速度為每小時(shí)60千米。在這架飛機(jī)的尾翼和水平翼表面上，裝置了1.6萬(wàn)多個(gè)太陽(yáng)能電池，其比較大能量的2.67千瓦，它是將太陽(yáng)能變成電能來驅(qū)動(dòng)單葉螺族槳旋轉(zhuǎn)，使飛機(jī)在空中飛行的。 </p> <p> 以太陽(yáng)能電池為動(dòng)力的小型汽車也已經(jīng)在墨西哥試制成功。這種汽車外形像一三輪摩托車，在車頂上架了一個(gè)裝有太陽(yáng)能的大篷，在太陽(yáng)照射下，太陽(yáng)能電池供給汽車電能，使汽車以每小時(shí)40千米的速度向前行駛。由于這輛汽車每天所獲得的電能只能行駛40分鐘，所以它不能跑遠(yuǎn)路。太陽(yáng)能電池片的功能用途！</p><div

太陽(yáng)電池經(jīng)過制絨、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。 </p> <p> 對(duì)于太陽(yáng)能電池來說，為了獲得盡可能高的光電轉(zhuǎn)化效率，對(duì)電池的結(jié)構(gòu)必須進(jìn)行詳細(xì)設(shè)計(jì)。金屬柵線負(fù)責(zé)把電池體內(nèi)的光生電流引到電池外部。太陽(yáng)電池柵線的比較好設(shè)計(jì)是以電池總功率損耗**小為依據(jù)的。 </p> <p> 柵線結(jié)構(gòu)設(shè)計(jì)得好，將使電池的串聯(lián)電阻**小，從而使功率損耗**小、輸出功率比較大，這對(duì)大面積功率輸出的單體太陽(yáng)能電池尤為重要。 </p> <p> 工藝上細(xì)柵線寬度的減小可以使所需的比較好細(xì)柵線間距減小，可以很大程度上減少頂層橫向電流總相對(duì)功率損耗和細(xì)柵線遮光相對(duì)功率損耗，從而減少電極引起的總的功率損耗。為了提高方阻的同時(shí)，降低由于電極引起的功率損耗，就需要增加細(xì)柵線條數(shù)、減小細(xì)柵線寬度。太陽(yáng)能電池單片體積是多大？北京非晶硅太陽(yáng)能電池片公司</p><p
