Hauv kev tsim cov roj teeb hnub ci perovskite thiab cov khoom siv optoelectronic, qhov tseeb ntawm cov txheej txheem txheej txheem ncaj qha txiav txim siab qhov ua tau zoo ntawm cov khoom siv photoelectric. Raws li cov khoom siv tseem ceeb ntawm cov khoom siv txheej txheem, qhov ceev ntawm granite (feem ntau 2600-3100kg / m³) tsis yog tsuas yog qhov qhia txog lub cev xwb tab sis kuj yog qhov tseem ceeb uas cuam tshuam rau kev ruaj khov, kev tiv thaiv kev co thiab kev ntseeg siab mus sij hawm ntev ntawm cov khoom siv. Cov hauv qab no yog kev tshuaj xyuas ntawm nws cov kev sib txuas sab hauv los ntawm plaub qhov loj me.
Kev tsim kho kom ruaj khov ntawm lub hauv paus ruaj khov "zero displacement"
Cov txheej txheem perovskite muaj qhov yuav tsum tau ua siab heev rau qhov tiaj tiaj ntawm lub substrate (Ra≤0.5μm), thiab txhua qhov kev hloov pauv ntawm lub hauv paus yuav ua rau cov txheej tuab tsis sib xws lossis qhov tsis zoo ntawm lub qhov. Granite nrog qhov ceev ntawm ≥3100kg / m³ tuaj yeem tsim cov pawg inertial muaj zog heev vim nws cov qauv mineral sib xyaw ua ke sab hauv. Hauv qee qhov TOPCon perovskite tandem roj teeb ntau lawm kab, tom qab siv lub hauv paus granite siab, qhov sib txawv ntawm cov txheej tuab ntawm cov khoom siv tau txo qis los ntawm ± 15nm mus rau ± 3nm nyob rau hauv ib puag ncig ntawm kev co tshuab siab (50-200Hz), txhim kho qhov sib xws ntawm cov kab tam sim no-voltage ntawm lub roj teeb.
2. Qhov cuam tshuam zoo ntawm kev sib raug zoo ntawm qhov ceev thiab kev co
Thaum lub sijhawm txheej txheem, qhov kev txav ceev ntawm lub taub hau txheej precision (nrog rau qhov ceev linear tshaj 800mm / s) yuav ua rau muaj kev cuam tshuam hauv cov khoom siv. Cov kev tshawb fawb qhia tau tias rau txhua 10% nce ntxiv hauv qhov ceev ntawm granite, qhov kev ua haujlwm ntawm kev co attenuation tuaj yeem txhim kho los ntawm 18%. Thaum qhov ceev ncav cuag 3100kg / m³, nws qhov zaus ntuj tuaj yeem qis li 12Hz, zoo zam qhov ntau yam kev co-sensitive (20-50Hz) ntawm cov khoom siv txheej. Ib pab pawg tshawb fawb German cov kev sim tau qhia tias lub hauv paus granite siab-density tau ua rau cov zaj duab xis tuab sib xws ntawm cov txheej txheem perovskite spin-coating los ntawm 27% thiab txo qhov tsis xws luag los ntawm 40%.
3. Kev ua haujlwm ruaj khov thermal zoo dua qub
Cov ntaub ntawv Perovskite muaj kev nkag siab heev rau qhov kub thiab txias hloov pauv. Kev hloov pauv ntawm 0.1 ℃ tuaj yeem ua rau muaj kev cuam tshuam ntawm cov lattice. Vim yog qhov sib nrug ntawm atomic ze dua sab hauv, qhov coefficient ntawm thermal expansion ntawm high-density granite (4-6 × 10⁻⁶ / ℃) yog 30% qis dua li ntawm cov ntaub ntawv ib txwm muaj. Hauv cov txheej txheem annealing (100-150 ℃), lub hauv paus high-density tuaj yeem tswj qhov thermal deformation ntawm cov khoom tseem ceeb ntawm cov khoom siv hauv ± 0.5μm, kom ntseeg tau tias cov txheej txheem tswj hwm nanoscale flatness tom qab kev kho mob kub siab thiab zam kev tawg txheej txheem los ntawm kev ntxhov siab thermal.
4. Kev ua haujlwm ntev "kev tiv thaiv kev qaug zog" lav
Cov khoom siv perovskite txheej ua haujlwm ntau dua 16 teev hauv ib hnub, thiab lub hauv paus yuav tsum tiv taus kev ntxhov siab tas mus li. Granite nrog qhov ceev ntawm 3100kg / m³ muaj lub zog compressive ntawm ≥200MPa thiab nws qhov kev tiv thaiv hnav yog tsib zaug ntawm cov hlau ib txwm muaj. Cov ntaub ntawv ntsuas qhov tseeb ntawm qee lub Hoobkas perovskite module tsim tawm qhia tau hais tias tom qab ua haujlwm tas mus li rau peb xyoos, qhov tseeb ntawm lub tshuab txheej nrog lub hauv paus granite siab-density txo qis tsuas yog 0.8%, thaum cov khoom siv nrog lub hauv paus qis-density txo qis 3.2% thaum lub sijhawm tib yam, txo qis cov nqi kho khoom siv thiab kev pheej hmoo ntawm lub sijhawm tsis ua haujlwm.
Xaus Lus: Kev xaiv qhov ceev ceev txhais tau tias xaiv qhov kev ua tau zoo
Txij li qhov kev ua kom raug ntawm nanoscale txheej mus rau kev ua haujlwm ruaj khov ntev ntawm cov kab ntau lawm, qhov ceev ntawm granite tau dhau los ua qhov tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm cov khoom siv perovskite txheej. Rau cov tuam txhab tsim khoom uas nrhiav kev ua haujlwm zoo thiab zoo, kev xaiv cov hauv paus granite zoo nrog lub peev xwm ntawm ≥3100kg / m³ (xws li ZHHIMG® cov khoom tau ntawv pov thawj) tsis yog tsuas yog lav qhov txheej txheem tam sim no tab sis kuj sawv cev rau kev nqis peev zoo rau kev txhim kho peev xwm yav tom ntej.
