Hnub Ci Vaj Huam Sib Luag Fais Fab Kev Ua Haujlwm

Lub photoelectric conversion efficiency ntawm monocrystalline silicon hnub ci zog nce mus txog qhov siab tshaj ntawm 24 feem pua, uas yog siab tshaj plaws ntawm txhua hom hnub ci hlwb. Txawm li cas los xij, cov nqi tsim khoom ntawm monocrystalline silicon solar cells yog siab heev uas lawv tsis tuaj yeem siv dav thiab dav. Nyob rau hauv cov nqe lus ntawm cov nqi ntau lawm, polycrystalline silicon hnub ci hlwb yog pheej yig dua li monocrystalline silicon hnub ci hlwb, tab sis lub photoelectric hloov dua siab tshiab efficiency ntawm polycrystalline silicon hnub ci hlwb yog ho txo. Tsis tas li ntawd, lub neej kev pab cuam ntawm polycrystalline silicon hnub ci hlwb tseem luv dua li monocrystalline silicon hnub ci hlwb. Yog li ntawd, nyob rau hauv cov nqe lus ntawm kev ua tau zoo thiab tus nqi, monocrystalline silicon solar cells yog me ntsis zoo dua.
Cov kws tshawb fawb tau pom tias qee cov khoom siv semiconductor haum rau siv los ua cov hnub ci photovoltaic hloov dua siab tshiab. Piv txwv li, CdS, CdTe; III-V compound semiconductor: GaAs, AIIPinP, thiab lwm yam; Nyias zaj duab xis hnub ci hlwb ua los ntawm cov semiconductors pom zoo heev photoelectric conversion efficiency. Cov ntaub ntawv semiconductor nrog ntau qhov sib txawv ntawm qhov sib txawv tuaj yeem nthuav dav ntau yam ntawm lub hnub ci zog nqus spectrum, yog li txhim kho photoelectric conversion efficiency. 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 semiconductor multicomponent, Cu (In, Ga) Se2 yog lub hnub ci lub teeb absorbing khoom nrog kev ua tau 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, ua tiav qhov kev hloov pauv photoelectric ntawm 18 feem pua.
