Nrog rau kev nce qib ntawm Tuam Tshoj lub hom phiaj "ob lub carbon", kev lag luam photovoltaic (PV) tab tom muaj kev loj hlob tsis tau muaj dua. Raws li ib qho txheej txheem tseem ceeb rau kev txhim kho kev ua haujlwm ntawm lub hnub ci thiab txhim kho kev ua haujlwm ntawm cov khoom siv, cov thev naus laus zis nqus tsev ua lub luag haujlwm tseem ceeb hauv ntau theem ntawm kev tsim khoom PV, tsav tsheb kev txhim kho kev lag luam thiab kev tsim kho tshiab.
Txheej Tshuab Nqus Tsev: Cov "Txheej Txheem Tsis Pom" Tom Qab PV Devices
Kev txheej txheej nqus tsev yog ib txoj kev siv los tso cov zaj duab xis nyias nyias rau ntawm qhov chaw ntawm lub substrate hauv qab qhov chaw nqus tsev, siv cov txheej txheem lub cev lossis tshuaj lom neeg - feem ntau yog PVD (Physical Vapor Deposition) thiab CVD (Chemical Vapor Deposition). Piv rau cov txheej txheem ntub dej ib txwm muaj, kev txheej txheej nqus tsev muab cov zaj duab xis zoo dua, kev nplaum zoo, kev tswj qhov tuab kom meej, thiab kev ua qias tuaj tsawg, ua rau nws yog ib kauj ruam tseem ceeb hauv kev tsim cov khoom siv photovoltaic ua haujlwm siab.
Cov Ntawv Thov Tseem Ceeb ntawm Lub Tshuab Nqus Tsev Txheej hauv Photovoltaics
1. Cov Tshuaj Pleev Xim Tiv Thaiv Kev Txav (AR) rau Cov Cell Crystalline Silicon
Kev siv cov txheej tiv thaiv kev cuam tshuam rau ntawm qhov chaw ntawm cov hlwb crystalline silicon yog qhov tseem ceeb heev rau kev txhim kho kev nqus lub teeb. Cov ntaub ntawv ib txwm muaj xws li silicon nitride (SiNx) feem ntau yog tso los ntawm kev siv Plasma Enhanced Chemical Vapor Deposition (PECVD), uas ua rau txo qhov kev poob ntawm kev cuam tshuam ntawm qhov chaw thiab ua rau lub hlwb ua haujlwm tau zoo dua.
2. Cov Yeeb Yaj Kiab Oxide Uas Muaj Pob Txhuv (TCO)
Hauv cov roj teeb hnub ci uas muaj zaj duab xis nyias, cov txheej TCO xws li ITO (Indium Tin Oxide) thiab AZO (Aluminum-doped Zinc Oxide) ua haujlwm ua cov electrodes pem hauv ntej tseem ceeb. Cov no feem ntau raug tso los ntawm magnetron sputtering, ib qho txheej txheem PVD uas ua kom muaj kev xa hluav taws xob siab, kev tiv taus qis, thiab kev ruaj khov zoo heev.
3. Cov Txheej Txheem Reflective thiab Barrier
Cov qauv Backsheet feem ntau muaj cov txheej txheej uas cuam tshuam (piv txwv li, Ag, Al) thiab cov txheej txheej thaiv (piv txwv li, SiOx, Al2O3), uas feem ntau kuj siv los ntawm kev txheej nqus tsev. Cov txheej txheej uas cuam tshuam txhim kho kev ntes lub teeb sab hauv, thaum cov txheej txheej thaiv txhim kho kev ruaj khov mus sij hawm ntev thiab tiv taus cov dej noo thiab kev ntxhov siab thermal.
4. Kev Tso Tawm Zaj Duab Xis Nyias Hauv Perovskite Lub Hnub Ci Cells
Cov roj teeb hnub ci perovskite uas tshwm sim tshiab muaj ntau txheej—xws li cov txheej thauj mus los, cov txheej sib txuas, thiab cov txheej encapsulation—txhua txheej xav tau kev tso dej kom raug thiab tsis ua puas tsuaj ntau. Cov txheej nqus tsev qhia tau tias muaj peev xwm ua tau zoo hauv qhov no, tshwj xeeb tshaj yog rau kev ua tiav cov yeeb yaj kiab loj uas tseem ceeb rau kev lag luam loj hlob.
Cov Qauv Kev Lag Luam thiab Cov Kev Xav Tau Khoom Siv
Raws li cov thev naus laus zis PV hloov zuj zus mus rau heterojunction (HJT) thiab perovskite / silicon tandem cells, qhov kev thov rau cov zaj duab xis nyuaj dua thiab kev ruaj khov ntawm zaj duab xis ntau dua tab tom nce ntxiv sai. Ua teb rau qhov no, cov tuam txhab tsim khoom siv tau qhia txog cov txheej txheem siab heev uas muaj kev ua haujlwm siab dua, kev ua haujlwm tsis siv neeg, thiab kev siv hluav taws xob zoo dua - xws li cov kab ke magnetron sputtering loj hauv thaj chaw thiab cov txheej txheem roll-to-roll vacuum coating - kom ua tau raws li qhov xav tau ntawm cov kab tsim khoom GW-scale.
Kev Siv Tshuab Txheej Txheem Ua Rau Yav Tom Ntej ntawm Lub Hnub Ci Muaj Zog
Kev txheej txheej nqus tsev tsis yog tsuas yog ib txoj kev ua tau zoo rau kev txhim kho kev ua haujlwm ntawm photovoltaic module xwb tab sis kuj yog ib qho tseem ceeb rau cov qauv cell ua haujlwm tau zoo ntawm tiam tom ntej. Txij li cov crystalline silicon ib txwm muaj mus rau cov kev daws teeb meem perovskite tshiab, txij li kev ua kom zoo dua qub mus rau kev koom ua ke tag nrho, cov txheej txheem txheej txheej tau sib txuas nrog kev lag luam hnub ci - ua rau txoj hauv kev mus rau yav tom ntej uas muaj cov pa roj carbon tsawg, ntsuab, thiab ua haujlwm tau zoo.
