太陽(yáng)能電池片的檢驗(yàn)項(xiàng)目有哪些？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黑龍江單晶太陽(yáng)能電池片色差,太陽(yáng)能電池片"

⑤峰值功率(pm)：峰值功率也叫比較大輸出功率或比較好輸出功率。峰值功率是指太陽(yáng)能電池片正常工作或測(cè)試條件下的比較大輸出功率，也就是峰值電流與峰值電壓的乘積：pm===im×um。峰值功率的單位是w(瓦)。太陽(yáng)能電池的峰值功率取決于太陽(yáng)輻照度、太陽(yáng)光譜分布和電池片的工作溫度，因此太陽(yáng)能電池的測(cè)量要在標(biāo)準(zhǔn)條件下進(jìn)行，測(cè)量標(biāo)準(zhǔn)為歐洲委員會(huì)的101號(hào)標(biāo)準(zhǔn)，其條件是：輻照度lkw／㎡、光譜aml.5、測(cè)試溫度25℃。 </p> <p> ⑥填充因子(ff)：填充因子也叫曲線因子，是指太陽(yáng)能電池的比較大輸出功率與開(kāi)路電壓和短路電流乘積的比值。計(jì)算公式為ff=pm/(isc×uoc)。填充因子是評(píng)價(jià)太陽(yáng)能電池輸出特性好壞的一個(gè)重要參數(shù)，它的值越高，表明太陽(yáng)能電池輸出特性越趨于矩形，電池的光電轉(zhuǎn)換效率越高。 </p> <p> 串、并聯(lián)電阻對(duì)填充因子有較大影響，太陽(yáng)能電池的串聯(lián)電阻越小，并聯(lián)電阻越大，填充因子的系數(shù)越大。填充因子的系數(shù)一般在0.5～0.8之間，也可以用百分?jǐn)?shù)表示。 </p> <p> ⑦轉(zhuǎn)換效率(η)：轉(zhuǎn)換效率是指太陽(yáng)能電池受光照時(shí)的比較大輸出功率與照射到電池上的太陽(yáng)能量功率的比值。即： </p> <p> η=pm(電池片的峰值效率)/a（電池片的面積）×pin（單位面積的入射光功率），其中pin=lkw／㎡=100mw／cm2。 </p> <p> <br />

拋光硅表面的反射率為35%,為了減少表面反射,提高電池的轉(zhuǎn)換效率,需要沉積一層氮化硅減反射膜。工業(yè)生產(chǎn)中常采用PECVD設(shè)備制備減反射膜。PECVD即等離子增強(qiáng)型化學(xué)氣相沉積。它的技術(shù)原理是利用低溫等離子體作能量源，樣品置于低氣壓下輝光放電的陰極上，利用輝光放電使樣品升溫到預(yù)定的溫度，然后通入適量的反應(yīng)氣體SiH4和NH3，氣體經(jīng)一系列化學(xué)反應(yīng)和等離子體反應(yīng)，在樣品表面形成固態(tài)薄膜即氮化硅薄膜。一般情況下，使用這種等離子增強(qiáng)型化學(xué)氣相沉積的方法沉積的薄膜厚度在70nm左右。這樣厚度的薄膜具有光學(xué)的功能性。利用薄膜干涉原理，可以使光的反射大為減少，電池的短路電流和輸出就有很大增加，效率也有相當(dāng)?shù)奶岣摺?黑龍江單晶太陽(yáng)能電池片色差</p><p
