Hnub ci iav, raws li cov khoom tseem ceeb rau photovoltaic thiab tsev -}}}}}}}}}}}}} Kev hloov pauv hluav taws xob, huab cua tsis kam, thiab kev pabcuam lub neej. Nws cov khoom tseem ceeb yog feem ntau yog suav nrog ntawm lub hauv paus iav txheej thiab ib txheej ua haujlwm lossis sib cuam tshuam. Kev sib xyaw ntawm cov ntaub ntawv no ua kom sib npaug cov ntsiab lus tseem ceeb xws li kev hloov chaw tseem ceeb, cuam tshuam, thiab kav ntev. Cov hauv qab no qhia txog cov ntawv xov tooj ntawm cov iav thiab cov khoom siv ua haujlwm zoo.
1. Lub hauv paus iav
Lub hauv paus txheej ntawm lub hnub ci iav yog feem ntau ua los ntawm high {0% {{% {%), 8% -10%), thiab me me ntawm magnesium Oxide (MGO) thiab txhuas oxide (al₂o₃). High-Purity Quartz xuab zeb (sio₂ cov ntsiab lus ntau dua los yog sib npaug rau 99%) yog cov khoom siv cov tseem ceeb uas txiav txim teeb pom kev loj. Kev kub-kub yaj tsim cov qauv kev sib txawv amorphous ua kom pom tseeb tshaj li 85% -88% rau cov kws kos duab vajtse).
Txhawm rau txhim kho kho qhov muag ntxiv, qee qhov siab- {}- Cov ncauj lus ntab qis dua lossis sib npaug 0.015%). Nws cov ntsiab lus hlau tsis tshua muaj nuj nqis txo cov roj ntsuab spectrum nqus, ua rau muaj kev tsis muaj xim thiab pob tshab iav. Qhov no ua rau nws tsim nyog tshwj xeeb rau cov duab photovoltaic thiab skylights, qhov twg muaj kev luam xim yog qhov tseem ceeb. Tsis tas li ntawd, tswj qhov kev nkhaus nkhaus thaum lub sijhawm yaj ua kom muaj kev cuam tshuam nrog GB / T 15763,009 tus qauv, nrog rau kev ntxhov siab sab hauv ntau dua lossis sib npaug rau 90 MPa).
Ii. Cov ntaub ntawv hloov kho ua haujlwm
Txhawm rau txhim kho lub zog ua hauj lwm zoo thiab ib puag ncig kev yoog raws li hnub ci, cov kev ua haujlwm tshwj xeeb yuav tsum tau sib xyaw ua ke lossis cov qauv. Cov txheej txheej no feem ntau tau cais rau hauv peb pawg hauv qab no:
1. anti {-} Reactive Txheej (ARC)
Arcs feem ntau yog suav nrog silicon dioxide (sio₂) - titanium dioxide (ti₂) composite nanofilm. Los ntawm kev tswj hwm cov yeeb yaj kiab thickness (kwv yees li 100 {}}}}}}}}}} 10%, yog li nce tag nrho cov kev hloov pauv. Qee cov khoom siv txoj kev sol-gel los tsim ib multilayer, graded-deptive-indicting qhov system, txuas ntxiv nthuav dav siv specting ntau (npog 380-1100 nm ntau).
2. Infrared txheej txheem reflective (qis - e lossis photovoltaic xaiv zaj duab xis)
To address the temperature sensitivity of photovoltaic modules (crystalline silicon cell efficiency decreases by approximately 0.4% for every 1°C increase in temperature), some solar glass incorporates metal oxide or silver-based composite films (such as indium tin oxide (ITO), silicon nitride (Si₃N₄), or silver-nickel-chromium alloy laminates). These selectively reflect thermal radiation in the near-infrared band (700-2500nm), reducing heat buildup within the module. For example, a single silver Low-E film can achieve an infrared reflectivity exceeding 70%, while a double silver film can further increase this to 85%, while maintaining high visible light transmittance (>85%).
3. Interlayer lossis encapsulant
Hauv photovoltaic module daim ntawv thov, Hnub Ci iav yog feem ntau lam tau lamer ntawm polyylene vinyl acetate (eva {{{- backsheet "qauv. PVB muaj kev cuam tshuam zoo heev thiab UV - thaiv cov khoom (txuas ntxiv<1%), making it suitable for architectural safety glazing. EVA, however, has become a mainstream encapsulation material due to its stronger adhesion to silicon cells (forming a three-dimensional network structure after cross-linking and curing). Its transmittance exceeds 90% and it can withstand long-term thermal cycling from -40°C to 120°C.
III. Cov Khoom Siv Innovation rau cov xwm txheej tshwj xeeb
With technological advancements, some new solar glass technologies are exploring perovskite quantum dot-doped glass (using a sol-gel method to uniformly disperse photosensitive materials within a glass matrix for broad-spectrum absorption) or flexible polymer-based glass (such as PET-glass composites, suitable for curved photovoltaic buildings). Furthermore, self-cleaning glass, coated with a titanium dioxide (TiO₂) photocatalytic film, decomposes organic matter and dirt under UV light. Combined with a hydrophobic coating (contact angle >100 degree), nws txo cov hmoov av nplaum, ntxiv txo tus nqi kho.
Hauv cov ntsiab lus, hnub ci iav cov khoom tsim yog qhov kev sib cav ntawm cov ntaub ntawv kev tshawb fawb, entrical engineering, thiab lub zog siv tshuab. Nws cov tub ntxhais dag nyob rau hauv maximizing photovoltaic hloov zuj zus kev nyab xeeb thaum ua kom muaj kev nyab xeeb los ntawm kev hloov kho lub hauv paus thiab kev tswj hwm cov txheej txheem ua haujlwm. Raws li thov rau photovoltaic kev sib xyaw ua ke nyob rau lub neej yav tom ntej, cov ntaub ntawv sib xyaw uas ua kom zoo nkauj nrog kev tshawb fawb thiab kev tsim kho siab.
