太陽(yáng)能電池的性能參數(shù)主要有：短路電流、開路電壓、峰值電流、峰值電壓、峰值功率、填充因子和轉(zhuǎn)換效率等。當(dāng)然還有電流和電壓參數(shù)的溫度系數(shù)， </p> <p> 各參數(shù)具體解釋如下： </p> <p> <br /> </p> <p> 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> ②開路電壓(uoc)：當(dāng)將太陽(yáng)能電池的正負(fù)極不接負(fù)載、使i=0時(shí)，此時(shí)太陽(yáng)能電池正負(fù)極間的電壓就是開路電壓，開路電壓的單位是伏特(v)。單片太陽(yáng)能電池的開路電壓不隨電池片面積的增減而變化，一般為0.5～0.7v。 </p> <p> ③峰值電流(im)：峰值電流也叫比較大工作電流或比較好工作電流。峰值電流是指太陽(yáng)能電池片輸出比較大功率時(shí)的工作電流，峰值電流的單位是安培(a)，遼寧焊帶太陽(yáng)能電池片好壞。 </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，遼寧焊帶太陽(yáng)能電池片好壞，遼寧焊帶太陽(yáng)能電池片好壞。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 />

光伏發(fā)電是利用半導(dǎo)體界面的光生伏***應(yīng)而將光能直接轉(zhuǎn)變?yōu)殡娔艿囊环N技術(shù)。這種技術(shù)的關(guān)鍵元件是太陽(yáng)能電池。太陽(yáng)能電池經(jīng)過(guò)串聯(lián)后進(jìn)行封裝保護(hù)可形成大面積的太陽(yáng)電池組件，再配合上功率控制器等部件就形成了光伏發(fā)電裝置。 </p> <p> 光伏發(fā)電的主要具體原理是半導(dǎo)體的光電效應(yīng)。光子照射到金屬上時(shí)，它的能量可以被金屬中某個(gè)電子全部吸收，電子吸收的能量足夠大，能克服金屬內(nèi)部引力做功，離開金屬表面逃逸出來(lái)，成為光電子。硅原子有4個(gè)外層電子，如果在純硅中摻入有5個(gè)外層電子的原子如磷原子，就成為N型半導(dǎo)體；若在純硅中摻入有3個(gè)外層電子的原子如硼原子，形成P型半導(dǎo)體。當(dāng)P型和N型結(jié)合在一起時(shí)，接觸面就會(huì)形成電勢(shì)差，成為太陽(yáng)能電池。當(dāng)太陽(yáng)光照射到P－N結(jié)后，空穴由P極區(qū)往N極區(qū)移動(dòng)，電子由N極區(qū)向P極區(qū)移動(dòng)，形成電流。 </p> <p> 上面所說(shuō)的光電效應(yīng)就是光照使不均勻半導(dǎo)體或半導(dǎo)體與金屬結(jié)合的不同部位之間產(chǎn)生電位差的現(xiàn)象。它首先是由光子(光波)轉(zhuǎn)化為電子、光能量轉(zhuǎn)化為電能量的過(guò)程；其次，是形成電壓過(guò)程。黑龍江非晶硅太陽(yáng)能電池片哪里便宜逆電流太陽(yáng)能電池片有什么壞處？</p><div

太陽(yáng)電池是一種對(duì)光有響應(yīng)并能將光能轉(zhuǎn)換成電力的器件。能產(chǎn)生光伏效應(yīng)的材料有許多種，如：?jiǎn)尉Ч?，多晶硅?非晶硅，砷化鎵，硒銦銅等。它們的發(fā)電原理基本相同，現(xiàn)已晶體硅為例描述光發(fā)電過(guò)程。 P型晶體硅經(jīng)過(guò)摻雜磷可得N型硅，形成P-N結(jié)。 </p> <p> 當(dāng)光線照射太陽(yáng)電池表面時(shí)，一部分光子被硅材料吸收;光子的能量傳遞給了硅原子，使電子發(fā)生了越遷，成為自由電子在P-N結(jié)兩側(cè)集聚形成了電位差，當(dāng)外部接通電路時(shí)，在該電壓的作用下，將會(huì)有電流流過(guò)外部電路產(chǎn)生一定的輸出功率。這個(gè)過(guò)程的的實(shí)質(zhì)是：光子能量轉(zhuǎn)換成電能的過(guò)程。 </p><p> 多晶硅薄膜太陽(yáng)能電池 </p> <p> <br /> </p> <p> 通常的晶體硅太陽(yáng)能電池是在厚度350～450μm的高質(zhì)量硅片上制成的，這種硅片從提拉或澆鑄的硅錠上鋸割而成。因此實(shí)際消耗的硅材料更多。為了節(jié)省材料，人們從70年代中期就開始在廉價(jià)襯底上沉積多晶硅薄膜，但由于生長(zhǎng)的硅膜晶粒大小，未能制成有價(jià)值的太陽(yáng)能電池。為了獲得大尺寸晶粒的薄膜，人們一直沒有停止過(guò)研究，并提出了很多方法。目前制備多晶硅薄膜電池多采用化學(xué)氣相沉積法，包括低壓化學(xué)氣相沉積（LPCVD）和等離子增強(qiáng)化學(xué)氣相沉積（PECVD）工藝。此外，液相外延法（LPPE）和濺射沉積法也可用來(lái)制備多晶硅薄膜電池?；瘜W(xué)氣相沉積主要是以SiH2Cl2、SiHCl3、Sicl4或SiH4,為反應(yīng)氣體,在一定的保護(hù)氣氛下反應(yīng)生成硅原子并沉積在加熱的襯底上，襯底材料一般選用Si、SiO2、Si3N4等。太陽(yáng)能電池片的技術(shù)參數(shù)?。?！</p><div

該工藝用于太陽(yáng)能電池片生產(chǎn)制造過(guò)程中，通過(guò)化學(xué)腐蝕法也即把硅片放在氫氟酸溶液中浸泡，使其產(chǎn)生化學(xué)反應(yīng)生成可溶性的絡(luò)和物六氟硅酸，以去除擴(kuò)散制結(jié)后在硅片表面形成的一層磷硅玻璃。在擴(kuò)散過(guò)程中，POCL3與O2反應(yīng)生成P2O5淀積在硅片表面。P2O5與Si反應(yīng)又生成SiO2和磷原子， </p> <p> 這樣就在硅片表面形成一層含有磷元素的SiO2，稱之為磷硅玻璃。去磷硅玻璃的設(shè)備一般由本體、清洗槽、伺服驅(qū)動(dòng)系統(tǒng)、機(jī)械臂、電氣控制系統(tǒng)和自動(dòng)配酸系統(tǒng)等部分組成，主要?jiǎng)恿υ从袣浞帷⒌獨(dú)?、壓縮空氣、純水，熱排風(fēng)和廢水。氫氟酸能夠溶解二氧化硅是因?yàn)闅浞崤c二氧化硅反應(yīng)生成易揮發(fā)的四氟化硅氣體。若氫氟酸過(guò)量，反應(yīng)生成的四氟化硅會(huì)進(jìn)一步與氫氟酸反應(yīng)生成可溶性的絡(luò)和物六氟硅酸。太陽(yáng)能電池板內(nèi)部構(gòu)造.黑龍江非晶硅太陽(yáng)能電池片哪里便宜</p><p

用來(lái)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(yáng)電池片、薄膜太陽(yáng)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(wèn)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(lái)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(lái)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 /> 遼寧焊帶太陽(yáng)能電池片好壞</p><p
