Hnub ci vaj huam sib luag, yog ib hom hnub ci zog rau hauv cov khoom siv hluav taws xob, yog ib hom kev siv hluav taws xob ntsuab, tab sis kuj tseem muaj cov khoom siv tshiab tam sim no, xws li lub tshuab rhaub dej, tsheb kauj vab, tsheb fais fab, thiab lwm yam, yog siv los ntawm lub hnub ci vaj huam sib luag, ces , hnub ci vaj huam sib luag yog dab tsi?
1. Polycrystalline silicon solar cells Kev tsim cov txheej txheem ntawm polycrystalline silicon solar cells zoo ib yam li monocrystalline silicon solar cells, tab sis lub photoelectric conversion efficiency ntawm polycrystalline silicon solar cells yog qis dua, thiab nws photoelectric conversion efficiency yog li 12%. Hais txog tus nqi tsim khoom, nws yog pheej yig dua li monocrystalline silicon solar cells, kev tsim cov khoom siv yooj yim, txuag hluav taws xob noj, thiab qis dua tag nrho cov nqi tsim khoom, yog li nws tau tsim zoo heev. Tsis tas li ntawd, kev pab cuam lub neej ntawm polycrystalline silicon Sichuan hnub ci hlwb tseem luv dua li ntawm monocrystalline silicon hnub ci hlwb. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo-nqi piv, monocrystalline silicon hnub ci hlwb yog me ntsis zoo dua.
2. Amorphous silicon solar cells Amorphous silicon Sichuan solar cells yog ib hom tshiab ntawm nyias zaj duab xis hnub ci hlwb uas tau tshwm sim xyoo 1976, uas txawv kiag li los ntawm kev tsim cov qauv ntawm monocrystalline silicon thiab polycrystalline silicon solar cells, cov txheej txheem yog yooj yim heev, silicon. cov khoom siv tsawg heev, kev siv hluav taws xob qis dua, nws lub ntsiab kom zoo dua yog tias nws tuaj yeem tsim hluav taws xob nyob rau hauv lub teeb tsis muaj zog. 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 kwv yees li 10%, thiab nws tsis ruaj khov txaus, thiab nws cov kev hloov pauv tau ploj mus nrog lub sijhawm txuas ntxiv.
3. Monocrystalline silicon solar cells Lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci hlwb yog li ntawm 15%, thiab qhov siab tshaj plaws mus txog 24%, uas yog lub siab tshaj plaws photoelectric conversion efficiency ntawm tag nrho cov hom ntawm lub hnub ci hlwb, tab sis cov nqi ntau lawm yog li ntawd loj heev. tsis tuaj yeem siv dav. Txij li thaum monocrystalline silicon feem ntau encapsulated nrog tempered iav thiab waterproof resin, nws muaj zog thiab ruaj khov, thiab nws cov kev pab cuam lub neej feem ntau ncav cuag 15 xyoo thiab mus txog 25 xyoo.
4. Multi-compound solar cells Multi-compound solar cells xa mus rau lub hnub ci hlwb uas tsis yog ua los ntawm ib qho khoom siv semiconductor. Muaj ntau yam kev tshawb fawb nyob rau hauv ntau lub teb chaws, feem ntau ntawm cov uas tseem tsis tau muaj industrially tsim. Semiconductor cov ntaub ntawv nrog gradient band gaps (lub zog theem sib txawv ntawm cov conduction band thiab valence bands) tuaj yeem nthuav dav ntau yam ntawm lub hnub ci zog nqus, yog li txhim kho qhov kev hloov pauv ntawm photoelectric. Raws li nws, nyias-zaj duab xis hnub ci hlwb nrog ntau dua photoelectric conversion efficiency dua silicon nyias-film hnub ci hlwb tuaj yeem tsim.
