Ekukhiqizweni okunembile kwamaseli elanga e-perovskite namadivayisi e-optoelectronic, ukunemba kwenqubo yokumboza kunquma ngqo ukusebenza kahle kokuguqulwa kwe-photoelectric kwemikhiqizo. Njengezinto eziyisisekelo eziyisisekelo zemishini yokumboza, ipharamitha yobuningi be-granite (ngokuvamile engu-2600-3100kg/m³) akuyona nje inkomba ebonakalayo kodwa isici esibalulekile esithinta kakhulu ukuzinza, ukumelana nokudlidliza kanye nokuthembeka kwesikhathi eside kwemishini. Okulandelayo ukuhlaziywa kokuxhumana kwayo kwangaphakathi kusuka ezicini ezine ezinkulu.
Ukwakhiwa okuphezulu kwesisekelo esiqinile "esingashukumi"
Izembozo zePerovskite zinezidingo eziphakeme kakhulu zokuthi indawo engaphezulu ye-substrate ibe bushelelezi (Ra≤0.5μm), futhi noma yikuphi ukufuduka kwesisekelo kungaholela ekuqineni okungalingani kwezembozo noma emaphutheni emigodi. I-Granite enobuningi obungu-≥3100kg/m³ ingakha isisindo esiqinile kakhulu se-inertial ngenxa yesakhiwo sayo samaminerali esihlanganiswe eduze ngaphakathi. Emgqeni othile wokukhiqiza ibhethri le-TOPCon perovskite tandem, ngemuva kokusebenzisa isisekelo se-granite esinobukhulu obuphezulu, ukuphambuka kobukhulu bezembozo kwemishini kwehle kusuka ku-±15nm kuya ku-±3nm ngaphansi kwendawo yokudlidliza kwemishini okunemvamisa ephezulu (50-200Hz), okuthuthukisa kakhulu ukuhambisana kwejika lamandla kagesi wamanje webhethri.
2. Umphumela omuhle wokuxhumana phakathi kokuqina kanye nokuncipha kokudlidliza
Ngesikhathi senqubo yokumboza, ukunyakaza kwesivinini esikhulu kwekhanda lokumboza ngokunemba (ngesivinini esiqondile esidlula u-800mm/s) kuthambekele ekubangeleni umsindo emishinini. Izifundo zibonisa ukuthi ngokunyuka ngakunye okungu-10% kobuningi be-granite, ukusebenza kahle kokunciphisa ukudlidliza kungathuthukiswa ngo-18%. Lapho ubukhulu bufika ku-3100kg/m³, imvamisa yayo yemvelo ingaba ngaphansi kuka-12Hz, igweme ngempumelelo ububanzi obuzwela ukudlidliza (20-50Hz) bemishini yokumboza. Ukuhlolwa kwethimba locwaningo laseJalimane kukhombisile ukuthi isisekelo se-granite esinobukhulu obuphezulu sikhulise ukufana kobukhulu befilimu yenqubo yokumboza i-perovskite ngo-27% futhi sanciphisa izinga lokukhubazeka ngo-40%.
3. Ukusebenza kokuqina kokushisa okuthuthukisiwe okuphezulu
Izinto zePerovskite zizwela kakhulu ekushintsheni kwezinga lokushisa. Ukushintsha kwe-0.1℃ kungabangela ukuphambuka kwe-lattice. Ngenxa yesikhala esiseduze se-athomu ngaphakathi, i-coefficient yokwanda kokushisa kwe-granite enobukhulu obuphezulu (4-6×10⁻⁶/℃) iphansi ngo-30% kunezinto ezivamile. Enqubweni yokufakelwa (100-150℃), isisekelo esinobukhulu obuphezulu singalawula ukuguqulwa kokushisa kwezingxenye ezibalulekile zemishini ngaphakathi kuka-±0.5μm, siqinisekise ukuthi ukugqoka kugcina ukuthamba kwe-nanoscale ngemuva kokwelashwa kokushisa okuphezulu futhi kugweme ukuqhekeka kokugqoka okubangelwa ukucindezeleka kokushisa.
4. Isiqinisekiso sokusebenza isikhathi eside "sokulwa nokukhathala"
Imishini yokumboza i-perovskite isebenza amahora angaphezu kwangu-16 ngosuku ngokwesilinganiso, futhi isisekelo sidinga ukumelana nokucindezeleka okuqhubekayo komshini. I-Granite enobukhulu obungu-3100kg/m³ inamandla okucindezela angu-≥200MPa futhi ukumelana kwayo nokuguguleka kuphindwe kahlanu kunokwensimbi evamile. Idatha yokulinganisa yangempela yefektri ethile ye-perovskite module ekhiqizwe ngobuningi ikhombisa ukuthi ngemva kokusebenza okuqhubekayo iminyaka emithathu, ukunemba kokubeka komshini wokumboza onesisekelo se-granite esinobukhulu obuphezulu kwehle ngo-0.8% kuphela, kuyilapho okomshini onesisekelo esinobukhulu obuphansi kwehle ngo-3.2% phakathi nenkathi efanayo, okunciphisa kakhulu izindleko zokulungisa imishini kanye nengozi yesikhathi sokungasebenzi.
Isiphetho: Ukukhetha ubuningi obukhulu kusho ukukhetha ukusebenza okuphezulu
Kusukela ekuqondeni kwe-nanoscale coating kuya ekusebenzeni okuzinzile kwesikhathi eside kwemigqa yokukhiqiza, ubuningi be-granite bube yinto eyinhloko ethonya ukusebenza kwemishini ye-perovskite coating. Kumabhizinisi akhiqizayo aphishekela ukusebenza kahle kanye nekhwalithi, ukukhetha izisekelo ze-granite zekhwalithi ephezulu ezinomthamo ongu-≥3100kg/m³ (njengemikhiqizo eqinisekisiwe ye-ZHHIMG®) akuqinisekisi nje kuphela inqubo yamanje kodwa futhi kumelela ukutshalwa kwezimali okunesu kokuthuthukiswa kwamandla esikhathini esizayo.
