Nyob rau hauv kev hloov pauv ntawm lub zog ntsuab, Building-Integrated Photovoltaics (BIPV) tau nce siab ua lub zog tseem ceeb ntawm kev txhim kho kom ruaj khov hauv kev lag luam kev tsim kho. Ntawm cov thev naus laus zis tshiab, cadmium telluride (CdTe) lub hnub ci iav sawv tawm nrog nws cov kev ua haujlwm siab, kev zoo nkauj, thiab cov khoom zoo rau ib puag ncig, ua rau nws yog qhov kev daws teeb meem tseem ceeb rau kev siv BIPV.
1. Kev Ua Haujlwm Zoo Tshaj Plaws Thaum Muaj Teeb Meem Tsawg
Cov iav hnub ci CdTe, uas paub txog nws qhov kev hloov pauv photoelectric zoo heev, tab tom dhau los ua cov khoom tseem ceeb hauv BIPV sector. Siv cov zaj duab xis nyias cadmium telluride ua txheej photovoltaic, nws hloov lub hnub ci mus ua hluav taws xob tau zoo. Piv rau cov roj teeb hnub ci silicon ib txwm muaj, cov iav CdTe ua haujlwm tau zoo txawm tias nyob rau hauv qhov chaw tsaus ntuj, muab kev pabcuam hluav taws xob zoo dua thiab ruaj khov rau cov tsev.
Kev siv cov iav hnub ci CdTe dav dav hauv cov tsev tsis yog tsuas yog ua tau raws li qhov xav tau hluav taws xob ntawm lub tsev xwb tab sis kuj tseem tuaj yeem pub lub zog ntau dhau rov qab rau hauv lub network, ua kom muaj kev siv hluav taws xob zoo tshaj plaws. Cov kev daws teeb meem hluav taws xob zoo no pab txo kev siv hluav taws xob thiab cov pa roj carbon dioxide, pab txhawb rau kev txhim kho ntawm cov tsev ntsuab.
2. Kev Ua Haujlwm Kub Zoo Tshaj Plaws
Cov roj teeb hnub ci CdTe nyias nyias muaj qhov kub qis, qhia tau tias nws yooj yim hloov mus rau qhov kub siab. Txawm tias thaum lub caij ntuj sov kub, cov roj teeb no tseem ua haujlwm tau zoo nrog kev ua haujlwm poob qis tsawg kawg nkaus. Qhov no ua rau cov roj teeb hnub ci CdTe yog qhov kev daws teeb meem zoo tshaj plaws rau kev tsim hluav taws xob hauv huab cua kub, muab kev txhawb nqa zoo rau cov tsev ntsuab thiab cov ntawv thov BIPV.
3. Lub Neej Ntev thiab Kev Ruaj Ntseg
Cov roj teeb hnub ci CdTe nyias-zaj duab kuj tseem ceeb rau lawv qhov ruaj khov thiab ruaj khov hauv qhov chaw sab nraum zoov. Raws li kev sim los ntawm National Renewable Energy Laboratory (NREL), CdTe modules khaws cia 88% ntawm lawv cov txiaj ntsig qub tom qab 27 xyoo ntawm kev ua haujlwm (1995-2021), nrog rau kev puas tsuaj tsuas yog 12%. Qhov sib piv, cov roj teeb crystalline silicon feem ntau muaj kev poob qis txog 20% ntawm kev ua haujlwm hauv tib lub sijhawm. Lub neej ntev no ua rau CdTe cells yog qhov chaw muaj zog rau cov tsev ntsuab thiab BIPV.
4. Kev Sib Tw Zoo nrog Architecture
Ib qho ntawm lub zog tseem ceeb ntawm CdTe lub hnub ci iav yog nws txoj kev tsim kho uas tuaj yeem hloov kho tau, ua raws li kev muaj tswv yim ntawm cov kws kes duab vajtse thiab cov neeg nyiam ntawm cov tswv tsev. Txawm hais tias yog xim, qauv, lossis qhov loj me, CdTe iav tuaj yeem hloov kho kom sib xyaw ua ke nrog lub tsev zoo nkauj. Qhov kev ywj pheej no tso cai rau CdTe lub hnub ci iav tsis yog tsuas yog ua lub zog xwb tab sis kuj yog ib qho khoom tsim, txhim kho ob qho tib si kev ua haujlwm thiab kev pom ntawm lub tsev.
5. Kev Sib Kis Teeb Zoo heev
Cov CdTe hnub ci modules sib xyaw cadmium telluride nrog cov iav conductive, muab kev xa lub teeb zoo thaum ua tau raws li qhov xav tau ntawm lub tsev. Muaj ntau yam xim, cov modules no ua kom lub teeb sib kis tau zoo, ua kom lawv pom kev zoo thiab siv tau zoo nrog lub tsev tsim.
6. Kev Nyab Xeeb Siab Dua
Cov modules hnub ci ib txwm muaj, thaum muab ib feem ntxoov ntxoo rau lub sijhawm ntev, yuav raug kev cuam tshuam los ntawm qhov kub hnyiab, qhov twg qhov kub hnyiab hauv zos los ntawm qhov hluav taws xob siab tuaj yeem txo qhov kev ua haujlwm thiab txo lub neej ntawm lub cev. Hauv cov xwm txheej hnyav, qhov no tuaj yeem ua rau muaj kev phom sij ntawm hluav taws. Cov modules CdTe, nrog lawv qhov hluav taws xob qis dua thiab txo qhov kub hnyiab, muaj cov teebmeem kub hnyiab tsawg kawg nkaus, ua kom muaj kev nyab xeeb thiab kev ruaj khov ntawm lub cev.
7. Kev vam khom tsawg kawg nkaus ntawm Tilt
Cov modules CdTe zoo heev hauv kev nqus lub teeb diffuse, ua rau lawv tsis tshua vam khom lub kaum sab xis ntawm kev teeb tsa. Txawm tias nyob rau hauv cov kaum sab xis heev, CdTe panels tseem muaj zog tsim hluav taws xob zoo dua li lwm cov modules, ua kom muaj kev hloov pauv hluav taws xob zoo hauv ntau yam kev teeb tsa. Qhov no ua rau CdTe panels yooj ywm thiab hloov tau yooj yim hauv BIPV daim ntawv thov.
8. Cov txiaj ntsig ntawm ib puag ncig thiab kev ruaj khov
Cov iav hnub ci CdTe yog tsim los ntawm kev siv cov khoom siv thiab cov txheej txheem uas tsis ua rau ib puag ncig puas tsuaj, ua raws li lub hom phiaj kev txhim kho kom ruaj khov. Piv rau cov roj teeb hnub ci uas siv silicon, kev tsim cov CdTe tsim cov khib nyiab tsawg dua thiab muaj qhov cuam tshuam me dua rau ib puag ncig. Ntxiv mus, nws lub neej ntev ua kom muaj kev ua haujlwm ruaj khov raws sijhawm, txo qhov xav tau hloov pauv ntau zaus thiab txo qis kev siv cov peev txheej thiab kev cuam tshuam rau ib puag ncig.
Hauv kev xaus lus, CdTe lub hnub ci iav sawv cev rau qhov kev daws teeb meem muaj zog thiab ruaj khov rau BIPV, muab kev ua haujlwm zoo, kev ywj pheej, kev nyab xeeb, thiab cov txiaj ntsig ib puag ncig rau cov qauv ntsuab niaj hnub.
