Lub 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 zog. Nws kuj yog ib yam khoom tshiab uas tam sim no tau siv dav, xws li lub tshuab rhaub dej, tsheb kauj vab, tsheb fais fab, thiab lwm yam, yog siv los ntawm cov hnub ci vaj huam sib luag Yog li, cov hnub ci vaj huam sib luag yog dab tsi?
(1) Polycrystalline silicon hnub ci cell
Kev tsim cov txheej txheem ntawm polycrystalline silicon hnub ci cell zoo ib yam li monocrystalline silicon hnub ci cell, tab sis lub photoelectric conversion efficiency ntawm polycrystalline silicon hnub ci cell yog txo ntau, thiab nws photoelectric conversion efficiency yog li ntawm 12%. Hais txog tus nqi tsim khoom, nws yog pheej yig dua ib zaug - siv lead ua silicon solar cells, cov ntaub ntawv yooj yim rau kev tsim, kev siv hluav taws xob txuag, thiab tag nrho cov nqi tsim khoom tsawg, yog li nws tau tsim ntau heev. Tsis tas li ntawd, lub neej kev pab cuam ntawm polycrystalline silicon hnub ci hlwb yog luv dua li ntawm monocrystalline silicon hnub ci hlwb. Hais txog kev ua haujlwm ntawm tus nqi, monocrystalline silicon hnub ci hlwb tseem zoo dua me ntsis.
(2) Amorphous silicon solar cell
Amorphous silicon Sichuan hnub ci cell yog ib yam tshiab ntawm nyias - zaj duab xis hnub ci cell uas tshwm sim nyob rau hauv 1976. Nws yog kiag li txawv los ntawm kev tsim qauv ntawm ib tug siv lead ua silicon thiab polycrystalline silicon solar cells. Cov txheej txheem yog heev yooj yim. Lub ntsiab kom zoo dua yog tias nws tseem tuaj yeem tsim hluav taws xob hauv cov teeb pom kev tsawg. Txawm li cas los xij, qhov teeb meem tseem ceeb ntawm amorphous silicon hnub ci hlwb yog qhov kev hloov pauv ntawm photoelectric tsawg, qib siab thoob ntiaj teb yog li 10%, thiab nws tsis ruaj khov txaus. Thaum lub sij hawm, lub conversion efficiency decays.
(3) Monocrystalline silicon hnub ci cell
Ib qho - crystal silicon hnub ci cell muaj qhov kev hloov pauv photoelectric txog li 15% thiab qhov siab tshaj plaws ntawm 24%. Qhov no yog lub siab tshaj plaws photoelectric conversion efficiency ntawm txhua hom ntawm lub hnub ci hlwb, tab sis cov nqi ntau lawm yog li loj heev uas nws yuav siv tsis tau universally. Vim tias monocrystalline silicon feem ntau ntim nrog cov iav tempered thiab cov dej tsis muaj dej, nws yog qhov ruaj khov thiab ruaj khov, nrog lub neej ua haujlwm txog li 15 xyoo thiab siab kawg ntawm 25 xyoo.
(4) Multi-cov khoom siv hluav taws xob hnub ci
Multicomponent solar cells hais txog lub hnub ci uas tsis yog ua los ntawm ib qho - cov khoom siv semiconductor. Muaj ntau ntau yam kawm nyob rau hauv ntau lub teb chaws, feem ntau ntawm cov uas tseem tsis tau muaj industrialized. Cov khoom siv semiconductor nrog ntau qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tuaj yeem nthuav dav ntau yam ntawm lub hnub ci nqus spectrum, yog li txhim kho qhov kev hloov pauv ntawm photoelectric. Raws li nws, nyias - zaj duab xis hnub ci cell nrog photoelectric hloov dua siab tshiab efficiency uas yog siab dua li ntawm silicon nyias - zaj duab xis hnub ci cell tuaj yeem tsim.
