Ka tsoelo-pele e tsoelang pele ea lipheo tsa "khabone e habeli" tsa Chaena, indasteri ea photovoltaic (PV) e ntse e hola ka mokhoa o sa tloaelehang. E le ts'ebetso ea bohlokoa ea ho ntlafatsa ts'ebetso ea lisele tsa letsatsi le ho ntlafatsa ts'ebetso ea lisebelisoa, theknoloji ea ho koahela ka vacuum e bapala karolo ea bohlokoa haholo mekhahlelong e mengata ea tlhahiso ea PV, e khanna ntlafatso ea indasteri le boqapi.
Ho Koahela ka Vacuum: "Ts'ebetso e sa Bonahaleng" e ka Morao ho Lisebelisoa tsa PV
Ho koahela ka vacuum ho bolela mokhoa oa ho beha lifilimi tse tšesaane holim'a substrate tlas'a maemo a vacuum, ho sebelisoa mekhoa ea 'mele kapa ea lik'hemik'hale - haholo-holo PVD (Physical Vapor Deposition) le CVD (Chemical Vapor Deposition). Ha ho bapisoa le mekhoa ea setso ea metsi, ho koahela ka vacuum ho fana ka ho tšoana ha filimi ho hoholo, ho khomarela ho matla, taolo e nepahetseng ea botenya, le tšilafalo e fokolang, e leng se etsang hore e be mohato oa bohlokoa tlhahisong ea lisebelisoa tsa photovoltaic tse sebetsang hantle.
Litšebeliso tsa Bohlokoa tsa ho Koahela ka Vacuum ho Photovoltaics
1. Liaparo tse sa Bonahaleng (AR) bakeng sa Lisele tsa Silicon tsa Crystalline
Ho sebelisa masela a thibelang ho bonesa holim'a lisele tsa silicon tse kristale ho bohlokoa ho ntlafatsa ho monngoa ha leseli. Lisebelisoa tse tloaelehileng tse kang silicon nitride (SiNx) hangata li bolokoa ka ho sebelisa Plasma Enhanced Chemical Vapor Deposition (PECVD), e fokotsang tahlehelo ea ho bonesa ha bokaholimo ka katleho le ho eketsa katleho ea sele ka kakaretso.
2. Lifilimi tsa Oxide e Tsamaisang ka Bophara (TCO)
Liseleng tsa letsatsi tse nang le filimi e tšesaane, likarolo tsa TCO tse kang ITO (Indium Tin Oxide) le AZO (Aluminium-doped Zinc Oxide) li sebetsa e le li-electrode tsa bohlokoa tse ka pele. Tsena hangata li kenngoa ka magnetron sputtering, ts'ebetso ea PVD e netefatsang phetiso e phahameng, resistivity e tlase, le botsitso bo botle ba tikoloho.
3. Mealo e Bonaletsang ka Morao le e Thibelang
Meaho ea pampiri e ka morao hangata e kenyelletsa mekhahlelo e bonahatsang (mohlala, Ag, Al) le mekhahlelo e thibelang (mohlala, SiOx, Al2O3), eo hape e sebelisoang hangata ka ho koahela ka vacuum. Mekhahlelo e bonahatsang e ntlafatsa ho tšoasoa ha leseli ka hare, ha mekhahlelo e thibelang e ntlafatsa botsitso ba nako e telele le ho hanyetsa mongobo le khatello ea mocheso.
4. Ho ntshwa ha Filimi e Nyenyane Diseleng tsa Letsatsi tsa Perovskite
Lisele tsa letsatsi tse hlahang tsa perovskite li kenyelletsa mekhahlelo e mengata—joalo ka mekhahlelo ea lipalangoang, mekhahlelo ea sebopeho, le liaparo tsa encapsulation—e 'ngoe le e 'ngoe e hloka ho beoa ha thepa ka nepo e tlase le e sa senyeheng. Ho koahela ka vacuum ho bontša bokhoni bo matla lefapheng lena, haholo-holo bakeng sa ho fihlela lifilimi tse tšoanang tsa sebaka se seholo tse bohlokoa bakeng sa ho hola ha khoebo.
Mekhoa ea Indasteri le Litlhoko tsa Lisebelisoa
Ha mahlale a PV a ntse a fetoha ho ea ho heterojunction (HJT) le lisele tsa perovskite/silicon tandem, tlhoko ea li-stack tsa lifilimi tse rarahaneng haholoanyane le botsitso bo boholo ba filimi e ntse e eketseha ka potlako. Ka lebaka leo, bahlahisi ba lisebelisoa ba hlahisa litsamaiso tse tsoetseng pele tse nang le phallo e phahameng ea matla, boiketsetso le tšebeliso e ntle ea matla—joalo ka litsamaiso tsa sputtering tsa magnetron tse ka hare ho sebaka se seholo le litsamaiso tsa ho roala vacuum tse roll-to-roll—ho fihlela litlhoko tsa tlhahiso ea bongata ba mela ea tlhahiso ea PV ea GW-scale.
Theknoloji ea ho Koahela e Matlafatsa Bokamoso ba Letsatsi
Ho koahela ka vacuum ha se feela mokhoa o pakiloeng oa ho ntlafatsa ts'ebetso ea mojule oa photovoltaic empa hape ke mohloli oa mantlha oa meaho ea sele e sebetsang hantle ea moloko o latelang. Ho tloha ho silicon e tloaelehileng ea kristale ho ea ho litharollo tse ncha tsa perovskite, ho tloha ntlafatsong ea thepa ho ea ho kopanngoa ha ts'ebetso e felletseng, theknoloji ea ho koahela e ntse e hokahana ka botebo le indasteri ea letsatsi - e bula tsela e lebisang bokamosong ba matla a nang le khabone e tlase, e tala le e sebetsang hantle haholo.
-Sengoloa sena se lokollotsoe kemoetsi oa mochini oa ho roala ka vacuum cleanerMochini o hloekisang oa Zhenhua.
