Lub zog hnub ci tau dhau los ua lwm txoj hauv kev tseem ceeb rau cov roj av fossil, muab cov khoom siv hluav taws xob uas ruaj khov thiab zoo rau ib puag ncig. Lub plawv ntawm cov thev naus laus zis vaj huam sib luag hnub ci yog lub hnub ci backplane, uas yog ib qho tseem ceeb rau kev ua haujlwm tag nrho thiab lub neej ntawm lub vaj huam sib luag hnub ci. Txawm li cas los xij, kev nkag siab txog kev ua tsis tiav ntawm lub hnub ci backplane yog qhov tseem ceeb rau kev ua kom ntseeg tau tias muaj kev ntseeg siab thiab ua haujlwm tau zoo ntawm cov kab ke zog hnub ci.
Lubdaim ntawv qhia hnub ciyog txheej sab nraud tshaj plaws ntawm lub hnub ci vaj huam sib luag, feem ntau yog ua los ntawm cov khoom siv polymer xws li polyvinyl fluoride (PVF) lossis polyvinyl chloride (PVC). Nws lub luag haujlwm tseem ceeb yog tiv thaiv cov khoom sab hauv ntawm lub hnub ci vaj huam sib luag (suav nrog cov photovoltaic cells) los ntawm cov yam ntxwv ib puag ncig xws li dej noo, UV hluav taws xob thiab kev ntxhov siab ntawm lub tshuab. Lub backsheet tsim zoo tsis tsuas yog txhim kho lub zog ntawm lub hnub ci vaj huam sib luag, tab sis kuj txhim kho nws cov kev ua haujlwm zoo.
Txawm hais tias nws tseem ceeb npaum li cas los xij, lub hnub ci backsheet kuj tseem tuaj yeem ua tsis tiav, cuam tshuam rau kev ua haujlwm ntawm koj lub vaj huam sib luag hnub ci. Ib qho ntawm cov laj thawj feem ntau ntawm kev ua tsis tiav backsheet yog kev puas tsuaj ntawm ib puag ncig. Cov vaj huam sib luag hnub ci feem ntau raug rau huab cua hnyav, suav nrog qhov kub thiab txias heev, av noo, thiab hluav taws xob UV. Raws sijhawm, cov yam no tuaj yeem ua rau cov khoom siv backsheet puas tsuaj, ua rau tawg, flaking, lossis delamination. Cov kev ua tsis tiav no tuaj yeem ua rau lub vaj huam sib luag hnub ci sab hauv cov khoom raug dej noo, ua rau xeb thiab txo qis kev ua haujlwm.
Lwm yam tseem ceeb uas ua rau lub hnub ci backsheet tsis ua haujlwm yog qhov tsis zoo ntawm kev tsim khoom. Qee zaum, qhov zoo ntawm cov ntaub ntawv siv hauv backsheet yuav tsis ua tau raws li cov qauv kev lag luam, ua rau tsis ua haujlwm sai. Kev sib txuas tsis txaus ntawm backsheet thiab lub hnub ci cell kuj tuaj yeem ua rau delamination, uas tuaj yeem cuam tshuam loj heev rau kev ua haujlwm ntawm lub vaj huam sib luag. Cov chaw tsim khoom yuav tsum ua raws li cov kev tswj hwm zoo kom ntseeg tau tias cov backsheets siv hauv cov vaj huam sib luag hnub ci ruaj khov thiab txhim khu kev qha.
Tsis tas li ntawd xwb, kev teeb tsa tsis raug kuj tseem tuaj yeem ua rau lub backsheet tsis ua haujlwm. Yog tias cov vaj huam sib luag hnub ci tsis tau teeb tsa kom raug, lawv yuav raug kev ntxhov siab ntau dhau, uas yuav ua rau lub backsheet tawg lossis sib cais ntawm lub vaj huam sib luag. Cov neeg teeb tsa yuav tsum ua raws li cov kev coj ua zoo tshaj plaws thiab cov lus qhia kom ntseeg tau tias cov vaj huam sib luag hnub ci tau teeb tsa kom ruaj ntseg thiab tuaj yeem tiv taus kev ntxhov siab ib puag ncig.
Yuav kom txo tau qhov kev pheej hmoo ntawm lub hnub ci backplane tsis ua haujlwm, kev saib xyuas thiab kev tshuaj xyuas tsis tu ncua yog qhov tseem ceeb. Cov tswv vaj huam sib luag hnub ci yuav tsum ua kev tshuaj xyuas tsis tu ncua kom paub txog cov cim ntawm kev hnav lossis kev puas tsuaj rau lub backplane. Kev kuaj pom cov teeb meem thaum ntxov tuaj yeem tiv thaiv cov teeb meem loj dua tom qab, kom ntseeg tau tias lub hnub ci tseem ua haujlwm tau zoo.
Tsis tas li ntawd xwb, kev nce qib hauv thev naus laus zis tab tom tsim txoj hauv kev rau cov ntaub ntawv hnub ci uas ruaj khov thiab txhim khu kev qha dua. Cov kws tshawb fawb tab tom tshawb nrhiav cov ntaub ntawv tshiab thiab cov txheej txheem uas tuaj yeem txhim kho qhov kev tiv thaiv ntawm cov khoom ib puag ncig. Kev tsim kho tshiab hauv cov txheej txheem tsim khoom kuj tseem tab tom tsim los txhim kho qhov kev nplaum thiab qhov zoo ntawm cov ntaub ntawv.
Hauv kev xaus, kev nkag siabdaim ntawv qhia hnub ciKev ua tsis tiav yog qhov tseem ceeb rau kev tswj hwm qhov ua tau zoo thiab lub neej ntev ntawm cov vaj huam sib luag hnub ci. Los ntawm kev nkag siab txog cov yam ntxwv uas ua rau kev ua haujlwm poob qis, suav nrog cov xwm txheej ib puag ncig, kev tsim khoom tsis zoo, thiab kev teeb tsa, cov neeg koom nrog tuaj yeem ua cov kauj ruam ua ntej los tiv thaiv kev ua tsis tiav. Raws li kev lag luam hnub ci txuas ntxiv mus, kev tshawb fawb thiab kev txhim kho txuas ntxiv yuav ua lub luag haujlwm tseem ceeb hauv kev txhim kho qhov ua tau zoo ntawm cov vaj huam sib luag hnub ci, thaum kawg ua rau cov kab ke hnub ci txhim khu kev qha thiab ua haujlwm tau zoo dua.
