Dab tsi yog hom hnub ci ci
Hnub ci vaj huam sib luag yog ib yam khoom uas hloov lub hnub ci zog rau hauv hluav taws xob. Nws yog ib hom ntsuab lub zog. Nws tseem yog khoom tshiab uas tam sim no siv tau dav. Piv txwv, lub tshuab ua kom sov, lub tsheb kauj vab, tsheb fais, thiab lwm yam, uas tau siv los ntawm lub hnub ci hluav taws xob. Yog li, lub hnub ci hluav taws xob yog dab tsi?
(1) Polycrystalline silicon solar cells Cov txheej txheem ntau lawm ntawm polycrystalline silicon solar cells zoo ib yam li ntawm monocrystalline silicon solar cells, tab sis photoelectric hloov dua siab tshiab ntawm polycrystalline silicon solar cells tau txo ntau heev, thiab nws cov photoelectric hloov dua siab tshiab yog li 12 %. Hais txog cov nqi tsim khoom, nws pheej yig dua li monocrystalline silicon solar cells, cov ntaub ntawv yooj yim rau kev tsim hluav taws xob, kev siv hluav taws xob tau txuag, thiab tag nrho cov nqi qis dua, yog li nws tau tsim hauv qhov nyiaj ntau. Tsis tas li ntawd, kev pab cuam lub neej ntawm polycrystalline silicon solar cells hauv Sichuan tseem luv dua li ntawm monocrystalline silicon solar cells. Hauv kev hais txog tus nqi kev ua tau zoo, monocrystalline silicon hnub ci hlwb zoo dua me ntsis.
(2) Amorphous silicon solar cell Amorphous silicon solar cell yog hom tshiab ntawm nyias zaj duab xis solar cell uas tau tshwm sim xyoo 1976. Nws yog qhov sib txawv ntawm monocrystalline silicon thiab polycrystalline silicon solar cells nyob rau hauv cov nqe lus ntawm kev tsim qauv. Cov txheej txheem yog yooj yim heev thiab kev siv cov khoom siv silicon yog tsawg. , Lub zog siv hluav taws xob tsawg dua, thiab nws cov txiaj ntsig tseem ceeb yog tias nws tuaj yeem tsim hluav taws xob nyob hauv qhov hluav taws xob tsawg. Txawm li cas los xij, qhov teeb meem tseem ceeb ntawm amorphous silicon solar cells yog tias qhov hloov hluav taws xob photoelectric efficiency tsawg, cov txheej txheem qib siab thoob ntiaj teb yog li 10%, thiab nws tsis ruaj khov. Raws li lub sijhawm los ntawm, nws hloov dua siab tshiab efficiency decays.
(3) Monocrystalline silicon solar cell Cov photoelectric hloov dua tshiab efficiency ntawm monocrystalline silicon solar cell yog li 15%, thiab qhov siab tshaj yog 24%. Qhov no yog qhov siab tshaj plaws ntawm kev tsim hluav taws xob photoelectric hloov dua siab tshiab ntawm txhua yam ntawm cov hnub ci hlwb, tab sis tus nqi tsim khoom yog ntau heev, yog li Nws tsis tuaj yeem siv thoob ntiaj teb. Txij li cov monocrystalline silicon feem ntau muab ntim nrog cov iav iav thiab cov dej ua kom zoo, nws yog cov ruaj khov thiab muaj kev pab lub neej ntev txog 15 xyoos, thiab txog 25 xyoos.
(4) Multi-element compound solar cell Ntau yam khoom sib txuas hnub ci cell hais txog lub hnub ci cell uas tsis yog ua los ntawm cov khoom siv sib tshooj ib nrab cov khoom siv. Muaj ntau yam kev tshawb fawb hauv ntau lub tebchaws, thiab feem ntau ntawm lawv tsis tau muaj kev lag luam. Cov khoom siv hluav taws xob semiconductor nrog qhov sib tshooj ntawm qhov sib txawv (lub zog qib qhov sib txawv ntawm cov kab sib xyaw thiab pawg valence) tuaj yeem nthuav lub hnub ci zog nqus hluav taws xob thiab txhim kho photoelectric hloov dua siab tshiab. Raws li nws, nyias-zaj duab xis hlwb hnub ci nrog hloov kho tau zoo dua qub photoelectric hloov dua siab tshiab dua li silicon nyias-zaj duab xis hnub ci hlwb tuaj yeem tsim.
