從現有的(de)(de)(de)情況來看，2019年(nian)新增(zeng)(zeng)光(guang)伏裝機量(liang)包括2019年(nian)完全新增(zeng)(zeng)的(de)(de)(de)指(zhi)標、未建(jian)(jian)成(cheng)(cheng)的(de)(de)(de)光(guang)伏領者項(xiang)目和扶(fu)貧項(xiang)目，以及歷(li)年(nian)遺留的(de)(de)(de)已建(jian)(jian)成(cheng)(cheng)但無指(zhi)標項(xiang)目。這個核算辦(ban)法跟很多企業對(dui)市(shi)場(chang)(chang)的(de)(de)(de)預(yu)(yu)估會有不同(tong)，制造企業更關注出(chu)貨量(liang)，已經建(jian)(jian)成(cheng)(cheng)但是(shi)沒有指(zhi)標的(de)(de)(de)項(xiang)目不在考慮(lv)范(fan)疇之內(nei)，但是(shi)這些項(xiang)目也(ye)會納入(ru)2019年(nian)新增(zeng)(zeng)的(de)(de)(de)規模中(zhong)，所以統(tong)計口徑(jing)的(de)(de)(de)不同(tong)也(ye)造成(cheng)(cheng)了大家(jia)對(dui)2019年(nian)市(shi)場(chang)(chang)預(yu)(yu)測的(de)(de)(de)分歧。

半導體(ti)在太(tai)陽光(guang)(guang)(guang)照(zhao)耀下(xia)，能量(liang)大于(yu)半導體(ti)禁帶寬度的光(guang)(guang)(guang)子(zi)(zi)(zi)，使半導體(ti)中原子(zi)(zi)(zi)的價(jia)電(dian)(dian)子(zi)(zi)(zi)受(shou)到(dao)激發而成為(wei)自由(you)電(dian)(dian)子(zi)(zi)(zi)，形(xing)成光(guang)(guang)(guang)生(sheng)電(dian)(dian)子(zi)(zi)(zi)-空(kong)(kong)穴對，也稱光(guang)(guang)(guang)生(sheng)載流子(zi)(zi)(zi)。太(tai)陽能電(dian)(dian)池由(you)PN結(jie)構成，在P區(qu)(qu)(qu)、空(kong)(kong)間電(dian)(dian)荷區(qu)(qu)(qu)和N區(qu)(qu)(qu)都會(hui)產生(sheng)光(guang)(guang)(guang)生(sheng)電(dian)(dian)子(zi)(zi)(zi)-空(kong)(kong)穴對，這些電(dian)(dian)子(zi)(zi)(zi)-空(kong)(kong)穴對由(you)于(yu)熱(re)運動(dong)，會(hui)向(xiang)各個(ge)方(fang)向(xiang)遷移(yi)。在空(kong)(kong)間電(dian)(dian)荷區(qu)(qu)(qu)產生(sheng)的與遷移(yi)進來的光(guang)(guang)(guang)生(sheng)電(dian)(dian)子(zi)(zi)(zi)-空(kong)(kong)穴對被內建電(dian)(dian)場分離，光(guang)(guang)(guang)生(sheng)電(dian)(dian)子(zi)(zi)(zi)被推(tui)進N區(qu)(qu)(qu)，光(guang)(guang)(guang)生(sheng)空(kong)(kong)穴被推(tui)進P區(qu)(qu)(qu)。在空(kong)(kong)間電(dian)(dian)荷區(qu)(qu)(qu)邊界處總的載流子(zi)(zi)(zi)濃度近似為(wei)0。
