Lithium ion powerwall

Feem ntau, crystalline silicon solar cell yog fabricated ntawm high {wafers 350-450m tuab, sawn los ntawm rub los yog nrum silicon ingots.

Cov txheej txheem saum toj no tau haus ntau cov khoom silicon. Txhawm rau kom txuag cov khoom, tshuaj vapor deposition (CVD) yog qhov muaj cov tshuaj txhuam hniav polycrystalline, suav nrog cov tshuaj polycricstalline, suav nrog cov tshuaj polycrolstall) thiab ntshav siab} Kua -} pase pegy (LPPE) thiab sputtering tso tseg tseem tuaj yeem siv los tsim polycrystalline silicon nyias- ua yeeb yaj kiab.

CVD feem ntau siv SIH2CL2, SIKCL3, Sicl4, lossis SHIH4 ua cov roj rechat. Nyob rau hauv cov huab cua tiv thaiv, silicon atoms reliu los ua silicon atoms, uas yog tom qab ntawd tso rau ntawm rhuab substrate. Substrate cov ntaub ntawv feem ntau suav nrog SI, SOO2, thiab SI3N4. Txawm li cas los xij, kev tshawb fawb tau pom tias kev tsim cov nplej loj loj ntawm tsis- silicon subttrates yog qhov nyuaj, thiab qhov khoob ntawm cov nplej tau yooj yim tsim.

Cov kev daws rau cov teeb meem no yog thawj txheej txheej nyias nyias ntawm amorphous silicon ntawm ib substrate siv LPCVD, tom qab ntawd Anneal cov txheej no los tsim cov nplej loj. Tuab polycrystalline silicon nyias cov yeeb yaj kiab yog tom qab ntawd muab tso rau ntawm cov noob no crystal. Yog li no, recrystallization thev naus laus zis yog qhov tsis muaj qhov tseem ceeb me me. Tam sim no, cov thev naus laus zis tseem ceeb siv yog cov khoom {{}}}}}}}} cheeb tsam melting recrystallization. Ntxiv nrog rau cov txheej txheem recrystalline, polycrystalline silicon nyias-}} {}}} crystalline cov solicon solar hlwb. Qhov no cuam tshuam txog kev hloov zuj zus kev ua tau zoo ntawm lub zog hnub ci.
