Leej twg cuam tshuam rau lub neej ntawm Backplane ntawm Tshiab Zog Photovoltaic Modules?

Hauv photovoltaic modules, photovoltaic rov qab daim ntawv yog cov khoom siv tiv thaiv, uas feem ntau ua lub luag haujlwm ntawm kev txhawb nqa cov khoom, cais cov dej vapor thiab oxygen, thiab yuav tsum tau tiv thaiv qhov kev sim ntawm qhov nyuaj thiab sib txawv sab nraum zoov ib puag ncig thoob ntiaj teb, yog li kev ntseeg tau ntawm nws. cov ntaub ntawv tseem ceeb heev. Nws cov qauv qhia hauv daim duab: los ntawm sab nraud mus rau sab hauv los ntawm huab cua saum npoo:

1) Fluorine zaj duab xis tiv thaiv txheej.

2) Adhesive txheej 1.

3) Txhawb txheej PET zaj duab xis.

4) Adhesive txheej 2.

5) Sab hauv kev tiv thaiv txheej.

(1) Fluorine zaj duab xis tiv thaiv txheej ntawm huab cua nto; Lub luag haujlwm tseem ceeb yog los tiv thaiv PET txheej txheej los ntawm ultraviolet thiab xuab zeb yaig, thiab ua kom tsis muaj zog ntawm PET degradation ceev, thiaj li ua kom muaj kev ua haujlwm zoo ntawm crystalline silicon module, "lub siab" ntawm photovoltaic module.

(2) Adhesive txheej 1 thiab nplaum txheej 2. Lub hom phiaj tseem ceeb yog txhawm rau khi cov fluorine zaj duab xis txheej thiab PET txheej ua ke, tsis muaj qhov cuam tshuam rau kev sib txuas vim qhov kev ua ntawm dej vapor, kub siab, thiab lwm yam, thiab nws thiaj li ua rau Kev sib cais ntawm cov fluorine zaj duab xis txheej thiab PET txheej thiab poob cov nyhuv tiv thaiv ntawm fluorine zaj duab xis txheej.

(3) PET txheej txheej. Nws tsuas yog ua lub luag haujlwm ntawm kev txhawb nqa thiab kev sib cais ntawm cov dej vapor thiab oxygen; nws tsis plam nws txoj kev txhawb nqa thiab kev tiv thaiv zoo vim yog qhov nrawm nrawm los yog tawg hauv qhov kev ua ntawm dej vapor, oxygen thiab kub thiab kub.

(4) Sab hauv fluorine zaj duab xis tiv thaiv txheej. Vim hais tias cov txheej sab hauv tsis yog nyob rau hauv kev sib cuag ncaj qha nrog rau sab nraum zoov atmospheric ib puag ncig, tsuas yog lub irradiation ntawm lub frontal tshav ntuj, kev siv yuav tsum tau ntawm lub puab txheej tsis nruj li cov huab cua tiv thaiv zaj duab xis.

Los ntawm qhov kev xav ntawm cov qauv ntawm photovoltaic modules, yog hais tias lub crystalline silicon wafer piv rau "lub plawv" ntawm lub module, ces lub photovoltaic backsheet tuaj yeem muab piv rau " armor" ntawm module, thiab fluorine zaj duab xis tiv thaiv txheej ntawm lub Cov huab cua saum npoo tuaj yeem muab piv rau Cov Khaub Ncaws "bulletproof" Cov khaub ncaws "lub cev" muaj peev xwm ua kom lub neej ntev ntawm "cov cuab yeej" thiab ua kom lub neej ntev ntawm tag nrho cov khoom. zaj duab xis tiv thaiv txheej yog qhov tseem ceeb heev.

Thickness yog ncaj qha ntsig txog cov khoom siv ua yeeb yaj kiab thiab muaj feem cuam tshuam rau kev laus. Thaum xaiv cov fluorine zaj duab xis nyias nyias, cov khoom tsim qauv tsim yuav tsum tau ua raws li ib puag ncig nyuaj ntawm cov cheeb tsam sib txawv, thiab cov fluorine zaj duab xis nrog cov tuab tuab yuav tsum tau xaiv los ua cov txheej txheem tiv thaiv.

Nyob rau hauv ib puag ncig nyuaj thiab sib txawv, cov yeeb yaj kiab tiv thaiv rau cov ntawv rov qab ntawm cov duab hluav taws xob photovoltaic yuav muaj qhov sib txawv ntawm qhov sib xyaw ua ke. Los ntawm qhov kev xav ntawm thinning ceev thiab ntau yam kev ua yeeb yam, nws raug nquahu kom ua kom lub thickness ntawm PVDF zaj duab xis rau sab nraum qab ntawm photovoltaic modules nyob rau hauv ib puag ncig hnyav. Thaum nws siab dua 25um lossis txawm tias 30um, nws tuaj yeem ua kom muaj kev nyab xeeb dua rau kev ua haujlwm ntev ntawm photovoltaic modules.
