style="text-indent:25px">1）太陽(yáng)能光強(qiáng)。太陽(yáng)能電池就是把太陽(yáng)光轉(zhuǎn)化為電的一種器件，在一般的情況下（注意條件），太陽(yáng)能電池的效率隨光強(qiáng)增加而增加的。再進(jìn)一步說(shuō)就是太陽(yáng)能電池效率和安裝地的綜合氣候條件有關(guān)系。2）電池的材料。不同的材料對(duì)光的吸收系數(shù)不同，禁帶寬度也不同，量子效率自然也不同，電池效率自然也不同了。一般來(lái)說(shuō)，單晶硅/多晶硅對(duì)光的系數(shù)系數(shù)遠(yuǎn)小于非晶硅的，所以非晶硅太陽(yáng)能電池厚度**有單晶硅/多晶硅厚度的百分之一即可較好的吸收太陽(yáng)光。另外理論上講GaAs太陽(yáng)能電池的極限效率要大于其他太陽(yáng)能電池的極限效率，因?yàn)镚aAs太陽(yáng)電池的禁帶寬度在1.4ev，和地面太陽(yáng)光光譜能量的**值**為接近。3）工藝水平。不同的工藝水平，電池的效率自然也不同，看看各個(gè)廠子就很明白了，為什么原材料幾乎都一樣，做出來(lái)的電池效率卻差別很大，原因就在這。工藝水平自然和設(shè)備水平有著重要的關(guān)系，一般來(lái)說(shuō)設(shè)備越是先進(jìn)工藝就越***，電池效率就越高（工藝是設(shè)備的產(chǎn)物，沒(méi)有設(shè)備工藝無(wú)法實(shí)現(xiàn)，都是空想）。典型的例子就是SiN:H減反膜以及倒金字塔結(jié)構(gòu)，一塊電池如果不采用這兩種工藝，效率差別會(huì)很**概8%左右）。</p></p><br
