Solar Vaj Huam Sib Luag Multicomponent Compounds

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. Ntau hom kev tshawb fawb tau ua nyob rau hauv ntau lub teb chaws, feem ntau tseem tsis tau muaj kev lag luam. Cov hom tseem ceeb yog raws li nram no: a) cadmium sulfide solar cells; b) gallium arsenide hnub ci hlwb; c) tooj liab indium selenium solar cells (tshiab multi band gap gradient Cu (In, Ga) Se2 nyias zaj duab xis hnub ci hlwb)
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 semiconductor nrog ntau qhov sib txawv ntawm lub zog hluav taws xob sib txawv (lub zog theem sib txawv ntawm cov khoom siv hluav taws xob thiab cov valence band), uas tuaj yeem nthuav dav lub hnub ci zog nqus spectrum ntau yam, yog li kev txhim kho lub photoelectric conversion efficiency. Raws li nws, nyias zaj duab xis hnub ci hlwb nrog ntau dua photoelectric conversion efficiency dua silicon nyias zaj duab xis hnub ci hlwb tuaj yeem tsim. Qhov kev ua tau zoo photoelectric hloov dua siab tshiab yog 18 feem pua, thiab hom nyias zaj duab xis hnub ci cell tsis tau pom tias muaj lub teeb hluav taws xob cuam tshuam kev ua haujlwm tsis zoo (SWE). Nws photoelectric conversion efficiency yog li ntawm 50-75 feem pua ​​​​siab tshaj ntawm cov lag luam nyias zaj duab xis hnub ci hlwb, uas yog lub siab tshaj plaws ntawm photoelectric conversion efficiency nyob rau hauv lub ntiaj teb no ntawm nyias zaj duab xis hnub ci hlwb.
Hloov tau roj teeb
Hnub ci vaj huam sib luag
Saj zawg zog nyias zaj duab xis hnub ci hlwb yog txawv los ntawm cov pa solar cells.
Cov hnub ci vaj huam sib luag feem ntau muaj cov qauv ntawm ob txheej iav nrog EVA cov khoom thiab lub roj teeb vaj huam sib luag ntawm lawv. Cov khoom zoo li no kuj hnyav heev thiab yuav tsum muaj lub bracket thaum lub sijhawm teeb tsa, ua rau lawv txav tau yooj yim.
Saj zawg zog nyias zaj duab xis hnub ci hlwb tsis tas yuav siv iav backplates thiab npog daim hlau, thiab lawv qhov hnyav yog 80 feem pua ​​​​sib dua li ntawm ob lub iav hnub ci cell modules. Cov hlwb siv tau siv PVC backplates thiab ETFE nyias zaj duab xis npog daim hlau tuaj yeem txawm tias yuav khoov, ua rau lawv nqa tau yooj yim. Thaum lub sij hawm kev teeb tsa, tsis tas yuav muaj kev txhawb nqa tshwj xeeb, uas tuaj yeem ntsia tau yooj yim ntawm lub ru tsev thiab siv rau lub ru tsev ntawm lub tsev pheeb suab.
Qhov tsis zoo yog tias qhov kev hloov pauv ntawm photoelectric tsawg dua li cov qauv siv lead ua silicon.
