Composition Of Solar Vaj Huam Sib Luag Ntawm Lub Hnub Ci Fais Fab Tsim Txheej Txheem

(1) Monocrystalline silicon hnub ci cell

Lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci hlwb yog li ntawm 15 feem pua, thiab qhov siab tshaj plaws yog 24 feem pua. Qhov no yog lub siab tshaj plaws photoelectric conversion efficiency ntawm txhua yam ntawm lub hnub ci hlwb, tab sis cov nqi ntau lawm yog li ntawd nws yuav tsis tau lug siv. Monocrystalline silicon feem ntau ntim nrog tempered iav thiab waterproof resin, yog li nws yog ruaj khov thiab ruaj khov, nrog rau kev pab cuam lub neej ntawm 15 xyoo feem ntau thiab 25 xyoo nyob rau hauv feem ntau.

(2) Polycrystalline silicon hnub ci cell

Cov txheej txheem ntau lawm ntawm polycrystalline silicon hnub ci hlwb zoo ib yam li cov monocrystalline silicon hnub ci hlwb, tab sis lub photoelectric conversion efficiency ntawm polycrystalline silicon hnub ci hlwb yuav tsum tau txo ntau, thiab nws photoelectric conversion efficiency yog li ntawm 12 feem pua ​​(Lub Xya hli ntuj 1, 2004). , Sharp, Nyiv, tau teev lub ntiaj teb kev ua haujlwm siab tshaj plaws polycrystalline silicon hnub ci hlwb nrog kev ua haujlwm ntawm 14.8 feem pua). Hais txog tus nqi tsim khoom, nws yog pheej yig dua li monocrystalline silicon hnub ci hlwb. Cov khoom siv tau yooj yim rau kev tsim, txuag hluav taws xob, thiab tag nrho cov nqi tsim khoom tsawg, yog li nws tau raug tsim los ntawm ntau tus neeg. 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. Nyob rau hauv cov nqe lus ntawm kev ua tau zoo tus nqi piv, monocrystalline silicon hnub ci hlwb yog me ntsis zoo dua.

(3) Amorphous silicon solar cell

Amorphous silicon solar cell yog ib hom tshiab ntawm nyias zaj duab xis hnub ci cell uas tau tshwm sim nyob rau hauv 1976. Nws yog txawv kiag li ntawm monocrystalline silicon thiab polycrystalline silicon hnub ci hlwb hauv kev tsim cov txheej txheem. Cov txheej txheem yog yooj yim heev, silicon cov khoom siv me me, thiab kev siv hluav taws xob qis dua. Nws 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 solar cells yog qhov tsis tshua muaj photoelectric conversion efficiency. Cov qib siab thoob ntiaj teb yog kwv yees li 10 feem pua, thiab nws tsis ruaj khov txaus. Nrog rau ncua sij hawm, nws conversion efficiency poob.

(4) Multicomponent compound solar cell

Ntau lub hnub ci vaj huam sib luag xa mus rau lub hnub ci hlwb uas tsis yog ua los ntawm ib qho khoom siv semiconductor. Muaj ntau ntau yam kev tshawb fawb nyob rau hauv ntau lub teb chaws, feem ntau uas tsis tau industrialized, feem ntau suav nrog cov hauv qab no: a) cadmium sulfide hnub ci hlwb b) gallium arsenide hnub ci hlwb c) tooj liab indium selenium hnub ci hlwb (tshiab multi-component band gap gradient. Cu (In, Ga) Se2 nyias zaj duab xis solar cells)

Cu (Nyob rau hauv, Ga) Se2 yog lub hnub ci lub teeb absorbing khoom nrog kev ua tau zoo heev. Nws yog cov khoom siv ntau yam semiconductor nrog gradient band sib txawv (zog theem sib txawv ntawm conduction band thiab valence band), uas tuaj yeem nthuav dav ntau yam ntawm lub hnub ci zog nqus spectrum thiab yog li txhim kho lub photoelectric conversion efficiency. Raws li nws, nyias-zaj duab xis hnub ci hlwb tuaj yeem tsim nrog kev hloov pauv photoelectric ntau dua li silicon nyias-film solar cells. Qhov kev ua tau zoo photoelectric hloov dua siab tshiab yog 18 feem pua. Tsis tas li ntawd, tsis muaj kev ua haujlwm degradation effect (SWE) tshwm sim los ntawm lub teeb hluav taws xob pom nyob rau hauv xws li nyias-film solar cells. Nws photoelectric conversion efficiency yog kwv yees li 50 ~ 75 feem pua ​​​​siab dua li ntawm cov lag luam nyias-zaj duab xis hnub ci vaj huam sib luag. Nws yog qib siab tshaj plaws ntawm photoelectric conversion efficiency nyob rau hauv lub ntiaj teb no ntawm nyias zaj duab xis hnub ci hlwb.
