Ncaj qha ntaus cov kev mob cov ntsiab lus ntawm perovskite solar cell technology kev lag luam
May 20, 2022
Ua ntej ntawm tag nrho cov, los ntawm thawj nam, raws li ib tug thib peb tiam solar cell technology, perovskite solar cell technology yeej ib txwm raug suav hais tias yog ib tug technology uas yuav hloov crystalline silicon hlwb nyob rau hauv lub neej yav tom ntej. Tom qab xyoo ntawm txoj kev loj hlob, perovskite solar cell technology tau zoo heev, thiab lub photoelectric hloov dua siab tshiab efficiency tau txuas ntxiv mus, thiab lub ncov tus nqi tau nyob ze rau ntawm crystalline silicon hlwb. Ua ke nrog tus nqi qis kom zoo dua ntawm perovskite hnub ci hlwb, nws lub peev xwm yav tom ntej tsis muaj kev txwv. Tab sis txawm tias qhov no, perovskite hnub ci hlwb tseem txwv los ntawm ntau yam, uas tau tiv thaiv kev lag luam loj ntawm cov hlwb.
Tam sim no, cov kev txwv tseem ceeb ntawm perovskite solar cells yog "loj" thiab "stability". Nyob rau hauv qhov kev txhawb tshwj xeeb rau perovskite hnub ci hlwb, nws tau hais tias txhawm rau daws qhov teeb meem ntawm kev ruaj ntseg ntawm thaj chaw loj perovskite hlwb thiab tau txais cov thev naus laus zis tseem ceeb thiab ua tiav cov txheej txheem thev naus laus zis rau thaj chaw loj ntawm perovskite hlwb, lub hauv paus tseem ceeb yog los daws cov teeb meem. teeb meem ntawm "loj cheeb tsam", "stability" teeb meem. Yog tias ob qho teeb meem no tau daws, kev lag luam ntawm perovskite hnub ci hlwb tuaj yeem ua kom nrawm, nqa txoj kev txo nqi tshiab rau kev tsim hluav taws xob photovoltaic.
Qhov thib ob, los ntawm qhov kev xav ntawm kev tsim cov qauv tshiab ntawm lub hnub ci kev tshawb fawb thiab kev sim platform, nws muaj ntau yam cuam tshuam rau photovoltaic cell technology. Ntawm qhov tod tes, nrog kev sib txawv ntawm txoj kev loj hlob ntawm lub hnub ci tshuab thev naus laus zis, cov kev taw qhia kev ua haujlwm tau dhau los ua ntau thiab ntau haiv neeg, tab sis cov qauv tsim, kev sim thiab lwm yam qauv feem ntau tsis tuaj yeem ua raws li qhov sib dhos, uas yog qhov tsis zoo rau kev tsim kho tshiab. tshuab. Nrog xws li lub platform rau hnub ci hlwb nrog cov qauv tshiab, nws yuav tsim lub luag haujlwm txhawb nqa rau cov thev naus laus zis muaj feem xyuam, kom cov thev naus laus zis no tuaj yeem raug them sai sai, thiab lawv cov nqi thiab peev xwm yuav raug ntsuas raws li qhov ncaj ncees. Ntawm qhov tod tes, lub platform yog qhov tseem ceeb rau cov uas tsis yog-PN junction exciton hom tshiab hnub ci hlwb. Raws li peb txhua tus paub, tam sim no crystalline silicon hlwb feem ntau paub txog kev hloov pauv ntawm hnub ci mus rau hluav taws xob hluav taws xob los ntawm sab hauv PN hlws ris. Cov lus nug cov ntaub ntawv qhia tau hais tias tus tshiab exciton hnub ci cell yog ib lub tshuab uas txhim kho kev hloov dua siab tshiab ntawm "electron-qhov khub" nyob rau hauv lub cell, uas yuav ua rau lub semiconductor nqus ib photon los tsim ntau excitons. "Kev hloov dua siab tshiab ntawm lub hnub ci hlwb tau zoo dua qub. Nws tau nkag siab tias cov tshiab exciton-hom solar cells tseem tuaj yeem muaj qhov dav dua lub teeb haum thiab tuaj yeem hloov tau lub teeb ntev-wavelength rau hauv hluav taws xob siv tau. Tam sim no, feem ntau muaj feem xyuam. Kev tshawb fawb yog nyob rau hauv chav kuaj, tab sis cov kev tshawb fawb muaj feem xyuam nrog lub peev xwm loj heev.Thaum paub tab, nws yuav ua rau muaj kev hloov pauv mus rau photovoltaic zog tsim.
Thaum kawg, los ntawm qhov kev xav ntawm kev tshawb fawb thiab kev loj hlob ntawm cov thev naus laus zis tseem ceeb rau lub hnub ci hlwb tshiab, qhov tseem ceeb tshaj plaws yog kev tshawb fawb txog cov ntsiab lus tshiab, cov tswv yim tshiab, cov ntaub ntawv tshiab thiab cov qauv tshiab ntawm lub hnub ci hlwb, uas ua rau cov thawj ob lub luag haujlwm tseem ceeb. . Nws kuj tseem tsim nyog rau kev lag luam photovoltaic fais fab tam sim no. Tam sim no, photovoltaic hlwb tau dhau los ua ntau thiab ntau haiv neeg, thiab hom photovoltaic modules pib tawg. Qhov laj thawj tob tshaj plaws nyob rau hauv kev nce qib ntawm thev naus laus zis thiab kev nce qib ntawm kev tshawb fawb theem pib ntawm kev tsim hluav taws xob photovoltaic. Kev saib ze dua ntawm cov lus qhia kev txhawb nqa tseem ceeb tuaj yeem pom, suav nrog yuav luag txhua cov lus qhia txhim kho lub hnub ci.
Lub hauv paus ntsiab lus ntawm lub hnub ci hluav taws xob tsim hluav taws xob: lub ntsiab lus universal ntawm lub hnub ci cell exciton tiam, kev sib cais, kev sib kis thiab kev sib koom ua ke;
Roj teeb tshuab:nto thiab interface passivation thiab hloov kho tshuab;
Cov ntaub ntawv tshiab:tsim thiab npaj thev naus laus zis ntawm cov khoom siv hluav taws xob tshiab nrog dav spectrum thiab kev ua haujlwm siab nqus;
Kev tsim kho tshiab:Cov qauv tshiab, cov txheej txheem tshiab thiab loj-thaj chaw fabrication technology ntawm kev ua haujlwm siab hnub ci hlwb.
Kev soj ntsuam tuaj yeem pom tau tias tam sim no kub ob sab, HJT, N-hom, dub silicon, PERC thiab lwm yam kev txhim kho tshuab kub kub thiab cov lus qhia hauv kev lag luam tsis suav nrog. Nyob rau hauv luv luv, tsuav nws yog ib tug technology thiab txheej txheem uas yuav txhim khu kev ua tau zoo ntawm lub hnub ci hlwb thiab txo nqi ntawm cov hlwb, nws muaj peev xwm txhawb nqa.
Zuag qhia tag nrho, kev txhawb nqa los ntawm peb yam yog lub hom phiaj heev, tsom mus rau kev txhim kho thev naus laus zis tshaj plaws hauv kev lag luam photovoltaic. Ntawm lawv, nws yog ib qho tseem ceeb heev rau kev loj hlob ntawm perovskite solar cells.
