Yuav ua li cas slim down solar cells

Hnub ci yog ib qho tseem ceeb rau kev loj hlob thiab lub neej ntawm txhua yam. Nws zoo li yuav inexhaustible. Yog li ntawd, lub hnub ci zog tau dhau los ua qhov zoo tshaj plaws "lub neej tom ntej" lub zog tom qab cua zog thiab dej zog. Yog vim li cas ntxiv cov "yav tom ntej" prefix yog lub hnub ci zog tseem nyob rau hauv nws cov me nyuam mos. Thiab txawm hais tias lub hnub ci kev siv hluav taws xob muaj ntau qhov zoo, kev lag luam hnub ci hluav taws xob hauv tsev tau dhau los vim tsis muaj zog hloov pauv muaj peev xwm thiab siv tsis txaus ntawm cov peev txheej.

Txoj kev loj hlob ntawm lub hnub ci zog tuaj yeem rov qab mus rau nruab nrab-19th caug xyoo. Thaum lub sijhawm ntawd, kev tsim khoom siv hluav taws xob ua hluav taws xob los tsim hluav taws xob ua rau tib neeg paub tias lub zog thermal thiab hluav taws xob tuaj yeem hloov mus rau ib leeg, thiab lub hnub ci zog yog qhov ncaj qha tshaj plaws ntawm kev tsim hluav taws xob thermal. Txog rau tam sim no, cov hnub ci vaj huam sib luag yog feem ntau siv dav hauv kev lag luam pej xeem. Lawv tuaj yeem nqus tau lub hnub ci thiab hloov lub hnub ci hluav taws xob ncaj qha lossis ncaj qha rau hauv hluav taws xob hluav taws xob los ntawm cov nyhuv photoelectric lossis photochemical nyhuv.

Feem ntau ntawm cov khoom siv hluav taws xob niaj hnub no siv cov roj teeb lithium rechargeable. Tshwj xeeb tshaj yog cov khoom siv hluav taws xob hauv xov tooj ntawm tes, vim tias lawv yog lub teeb yuag, txav tau yooj yim thiab muaj ntau daim ntawv thov kev ua haujlwm, cov neeg siv tsis txwv los ntawm ib puag ncig thaum siv, thiab lub sijhawm ua haujlwm ntev. Yog li ntawd, cov roj teeb lithium tau dhau los ua qhov kev xaiv tshaj plaws txawm tias lawv cov roj teeb tsis muaj zog.

Piv nrog cov roj teeb lithium, ib qho ntawm qhov tsis zoo ntawm lub hnub ci hlwb yog qhov pom tseeb, uas yog, lawv tsis tuaj yeem sib cais los ntawm lub hnub ci. Kev hloov pauv ntawm lub hnub ci zog rau hauv hluav taws xob hluav taws xob yog synchronized nrog lub hnub ci hauv lub sijhawm. Yog li ntawd, rau lub hnub ci zog, nws tsuas yog siv tau thaum nruab hnub lossis tsuas yog hnub ci xwb. Txawm li cas los xij, tsis zoo li cov roj teeb lithium, tsuav yog lawv tau them tag nrho, lawv tuaj yeem tso tawm tag nrho los ntawm kev txwv ntawm lub sijhawm thiab ib puag ncig thiab tuaj yeem siv tau yooj yim.

Teeb meem hauv "downsizing"hnub ci hlwb

Vim tias lub hnub ci cell lawv tus kheej tsis tuaj yeem khaws cov hluav taws xob hluav taws xob, uas yog cov kab mob loj heev rau kev siv cov tswv yim, cov kws tshawb fawb tau los nrog lub tswv yim los siv lub hnub ci hlwb ua ke nrog cov roj teeb uas muaj peev xwm loj heev. Lead-acid roj teeb yog hom siv ntau tshaj plaws ntawm lub hnub ci fais fab mov. Class loj muaj peev xwm roj teeb. Kev sib xyaw ua ke ntawm ob yam khoom ua rau lub hnub ci loj heev dhau los ua ntau "loj". Yog tias koj xav siv nws rau cov khoom siv txawb, koj yuav tsum xub mus dhau ntawm cov txheej txheem "downsizing".

Vim hais tias lub zog hloov dua siab tshiab tsis siab, lub hnub ci cheeb tsam ntawm lub hnub ci hlwb feem ntau yog loj, uas yog thawj qhov kev nyuaj nyuaj uas tau ntsib hauv lawv txoj kev "downsizing". Qhov kev txwv tam sim no ntawm lub hnub ci zog hloov pauv yog kwv yees li 24%. Piv nrog rau kim solar vaj huam sib luag ntau lawm, tshwj tsis yog nws yog siv nyob rau hauv ib tug loj cheeb tsam, nws practicality yuav txo tau heev, cia ib leeg siv nyob rau hauv mobile pab kiag li lawm.

Vim tias lub zog hloov pauv tsis siab, qhov chaw tshav ntuj ntawm lub hnub ci yog feem ntau loj dua.

Yuav ua li cas "slim down" solar cells?

Kev sib koom ua ke ntawm cov hnub ci hnub ci nrog cov roj teeb lithium rov ua dua yog ib qho kev tshawb fawb tam sim no thiab kev txhim kho cov lus qhia ntawm cov kws tshawb fawb tshawb fawb, thiab nws kuj yog ib txoj hauv kev zoo los txhawb lub hnub ci. Cov khoom siv hluav taws xob ntau tshaj plaws yog lub hwj chim bank. Los ntawm kev hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob thiab khaws cia rau hauv cov roj teeb lithium, lub hnub ci fais fab nyiaj tuaj yeem them cov xov tooj ntawm tes, cov koob yees duab digital, ntsiav tshuaj thiab lwm yam khoom, uas yog ob qho tib si txuag hluav taws xob thiab ib puag ncig zoo.

Lub hnub ci hlwb uas tuaj yeem ua tiav kev lag luam tiag tiag yog muab faib ua ob pawg: thawj qeb yog crystalline silicon hlwb, suav nrog polycrystalline silicon thiab monocrystalline silicon hlwb, uas suav nrog ntau dua 80% ntawm kev ua lag luam; qeb thib ob yog nyias zaj duab xis hlwb, uas ntxiv subdivided rau hauv Amorphous silicon cells muaj cov txheej txheem yooj yim thiab tus nqi qis, tab sis lawv cov kev ua tau zoo yog tsawg thiab muaj cov tsos mob ntawm kev poob qis.

Nyias zaj duab xis hnub ci hlwb tsuas yog ob peb millimeters tuab thiab tuaj yeem khoov thiab quav. Lawv tuaj yeem siv ntau yam khoom sib txawv ua cov khoom siv substrate. Lawv tuaj yeem txuas ncaj qha rau cov roj teeb lithium rau kev them nyiaj, uas txhais tau hais tias lub hnub ci hnub ci tuaj yeem tsim los rau hauv cov khoom siv hluav taws xob tshiab. Nws tseem ua tau heev. Ntxiv mus, hom charger no tuaj yeem nthuav tawm hauv cov duab sib txawv, ua rau nws yooj yim dua rau nqa. Piv txwv li, dai rau ntawm lub hnab tsev kawm ntawv lossis khaub ncaws tuaj yeem them lub xov tooj ntawm tes, thiab cov teeb meem roj teeb tau yooj yim daws tau.

Ntau tus neeg tsim khoom tam sim no ntseeg tias cov roj teeb lithium ua los ntawm graphene yog qhov tseem ceeb hauv kev daws teeb meem roj teeb lub neej ntawm cov khoom siv hluav taws xob txawb. Yog tias qhov hloov pauv ntawm lub hnub ci ntawm lub hnub ci hauv ib cheeb tsam tuaj yeem txhim kho tau zoo, ces daim ntawv txias ntawm kev them nyiaj mobile txhua lub sijhawm thiab nyob qhov twg yuav dhau los ua lub zog yav tom ntej. Txoj hauv kev zoo los siv cov lus nug.

Cov ntsiab lus: Hnub ci zog yog qhov khoom plig zoo tshaj plaws, tab sis kev siv lub hnub ci zog tseem tsis tau nrov heev. Tseem muaj teeb meem nrog tus nqi siab thiab kev hloov pauv qis hauv kev siv lub hnub ci zog los tsim hluav taws xob. Tsuas yog los ntawm kev ua kom muaj txiaj ntsig ntawm kev hloov pauv ntawm lub hnub ci zog hauv ib cheeb tsam tuaj yeem peb siv lub zog zoo thiab ua tiav qhov kev hloov pauv zoo tshaj plaws ntawm lub hnub ci zog mus rau lub zog hluav taws xob. Txij thaum ntawd los, kev txav ntawm lub hnub ci hlwb yuav tsis muaj teeb meem ntxiv lawm.
