Lub hnub ci vaj huam sib luag yog ib qho cuab yeej uas hloov lub hnub ci hluav taws xob ncaj qha lossis ncaj qha mus rau hauv hluav taws xob hluav taws xob los ntawm cov nyhuv photoelectric lossis photochemical nyhuv los ntawm kev nqus hnub ci.Cov khoom tseem ceeb ntawm feem ntau cov hnub ci vaj huam sib luag yog "silicon".Cov photons yog absorbed los ntawm cov khoom siv silicon;lub zog ntawm cov photons yog pauv mus rau silicon atoms, uas ua rau cov electrons hloov thiab ua dawb electrons uas sib sau rau ntawm ob sab ntawm PN hlws ris los tsim ib qho kev sib txawv.Thaum lub tshuab hluav taws xob sab nraud tau qhib, nyob rau hauv qhov kev txiav txim ntawm qhov hluav taws xob no, Yuav muaj qhov tam sim no ntws los ntawm cov hluav taws xob sab nraud los tsim kom muaj lub zog tso zis.Lub ntsiab ntawm cov txheej txheem no yog: cov txheej txheem ntawm hloov photon zog rau hauv hluav taws xob lub zog.
Solar Vaj Huam Sib Luag Lub Hwj Chim
Lub hnub ci hluav taws xob AC lub zog tsim hluav taws xob yog tsim los ntawm cov hnub ci vaj huam sib luag, cov tswj hwm, inverters thiab roj teeb;lub hnub ci DC lub zog tsim hluav taws xob tsis suav nrog lub inverter.Txhawm rau ua kom lub hnub ci hluav taws xob tsim hluav taws xob los muab lub zog txaus rau lub nra, nws yog ib qho tsim nyog yuav tsum xaiv txhua yam raws li lub zog ntawm cov khoom siv hluav taws xob.Siv 100W tso zis hluav taws xob thiab siv nws li 6 teev hauv ib hnub ua piv txwv los qhia txog txoj kev suav:
1. Ua ntej, xam cov watt-teev noj ib hnub (nrog rau qhov poob ntawm lub inverter): yog hais tias lub conversion efficiency ntawm lub inverter yog 90%, ces thaum lub hwj chim tso zis yog 100W, qhov tseeb tso zis hwj chim yuav tsum yog 100W / 90% = 111 W;Yog tias nws siv 5 teev hauv ib hnub, lub zog tso zis yog 111W * 5 teev = 555Wh.
2. xam lub hnub ci vaj huam sib luag: Raws li lub hnub ci hnub ci lub sij hawm ntawm 6 teev, thiab xav txog qhov kev them nqi thiab qhov poob thaum lub sij hawm them nqi, cov zis hluav taws xob ntawm lub hnub ci vaj huam sib luag yuav tsum yog 555Wh / 6h / 70% = 130W.Ntawm lawv, 70% yog lub zog tiag tiag siv los ntawm lub hnub ci vaj huam sib luag thaum lub sijhawm them nyiaj.
Hnub ci vaj huam sib luag zog tsim efficiency
Lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci zog yog mus txog 24%, uas yog lub siab tshaj plaws photoelectric conversion efficiency ntawm tag nrho cov hom ntawm lub hnub ci hlwb.Tab sis monocrystalline silicon hnub ci hlwb yog kim heev los ua kom lawv tseem tsis tau siv dav thiab siv dav hauv ntau.Polycrystalline silicon hnub ci hlwb yog pheej yig dua li monocrystalline silicon hnub ci hlwb nyob rau hauv cov nqe lus ntawm cov nqi ntau lawm, tab sis lub photoelectric conversion efficiency ntawm polycrystalline silicon hnub ci hlwb yog tsawg dua.Tsis tas li ntawd, lub neej kev pab cuam ntawm polycrystalline silicon hnub ci hlwb tseem luv dua li ntawm monocrystalline silicon hnub ci hlwb..Yog li ntawd, nyob rau hauv cov nqe lus ntawm cov nqi kev ua tau zoo, monocrystalline silicon hnub ci hlwb yog me ntsis zoo dua.
Cov kws tshawb fawb tau pom tias qee cov khoom siv semiconductor yog tsim rau hnub ci photoelectric conversion films.Piv txwv li, CdS, CdTe;III-V compound semiconductors: GaAs, AIIPinP, thiab lwm yam.nyias zaj duab xis hnub ci hlwb ua los ntawm cov semiconductors qhia zoo photoelectric conversion efficiency.Cov ntaub ntawv semiconductor nrog ntau qhov sib txawv ntawm lub zog sib txawv tuaj yeem nthuav dav cov spectral ntau yam ntawm lub hnub ci zog nqus, yog li txhim kho cov kev hloov pauv photoelectric.Yog li hais tias ib tug loj tus naj npawb ntawm cov tswv yim siv ntawm nyias zaj duab xis hnub ci hlwb qhia broad prospects.Ntawm cov khoom siv ntau yam khoom siv semiconductor, Cu (In, Ga) Se2 yog cov khoom siv hnub ci zoo heev.Raws li nws, nyias-zaj duab xis hnub ci hlwb nrog kev hloov pauv photoelectric ntau dua li silicon tuaj yeem tsim tau, thiab tus nqi hloov pauv photoelectric uas tuaj yeem ua tiav yog 18%.
Lifespan ntawm solar panels
Lub neej kev pab cuam ntawm lub hnub ci vaj huam sib luag yog txiav txim siab los ntawm cov ntaub ntawv ntawm lub hlwb, tempered iav, EVA, TPT, thiab lwm yam. Feem ntau, kev pab cuam lub neej ntawm cov vaj huam sib luag tsim los ntawm cov tuam txhab uas siv cov ntaub ntawv zoo dua tuaj yeem ncav cuag 25 xyoo, tab sis nrog kev cuam tshuam ntawm ib puag ncig, solar cells Cov khoom siv ntawm lub rooj tsavxwm yuav muaj hnub nyoog dhau sijhawm.Raws li ib txwm muaj, lub zog yuav raug txo qis los ntawm 30% tom qab 20 xyoo ntawm kev siv, thiab 70% tom qab siv 25 xyoo.
